Remarks
- Where flight visibility has been reduced to not less than 1500m, flights may be permitted at speeds that give adequate opportunity to observe other traffic or any obstacles in time to avoid collision (dependent on the country regulations).
- Helicopters may be permitted to operate in less than 1500m flight visibility if they can observe other traffic and any obstacles in time to avoid collision (depends on country regulations).
- The VMC minima in Class A airspace are included for guidance to pilots and do not imply acceptance of VFR flights in Class A airspace automatically.
Transition Altitude Consideration
⚠ When the height of the transition altitude is lower than 3050m or 10000ft AMSL, FL100 (flight level) should be used.
Initial Clearance/Clearance To or Out of the Zone
VFR Operations: Entry, Exit & Transit
Visual Flight Rules (VFR) flights primarily navigate using visual references such as roads, rivers, and landmarks. Specific VFR charts provide essential guidance, including entry/exit routes, compulsory reporting points, and designated holding patterns for controlled airspace operations.
Key Considerations:
- VFR aircraft are not provided separation from other traffic by ATC but must be given traffic advisories.
- Pilots must self-separate and comply with ATC instructions for control zone entry and exit.
- Wake turbulence separation applies to VFR departures following larger aircraft.
- When necessary, ATC may delay VFR movements to integrate them efficiently with IFR operations.
VFR Entry & Exit Procedures
Designated entry and exit routes allow VFR traffic to safely enter and depart controlled airspace. These routes:
- Lead aircraft between the aerodrome and uncontrolled airspace.
- Require position reports at compulsory reporting points.
- May have restrictions depending on runway configurations or traffic patterns.
Entry Procedure:
- The pilot requests entry via a published route.
- ATC provides QNH, active runway, and entry clearance.
- The pilot reports passing each mandatory reporting point.
- If no further instructions are given, the pilot follows the designated holding pattern before entering the circuit.
Exit Procedure:
- The controller issues departure clearance via a designated route.
- The pilot follows the assigned route, reporting their position at the last compulsory point before exiting controlled airspace.
- ATC releases the pilot from frequency once outside controlled airspace.
Note: Any turns after takeoff, particularly right turns, require explicit ATC authorization to avoid conflicting with other traffic.

VFR Transit Through Controlled Airspace
VFR pilots may request clearance to transit a control zone without landing. Handling of these flights follows a similar process as entries, with additional emphasis on separation from other aircraft.
- The pilot requests transit clearance, specifying routing and altitude.
- ATC provides a transit route and altitude restriction.
- The pilot follows the assigned route and exits controlled airspace as directed.
- ATC releases the aircraft from frequency upon exit.
VFR Aerodrome Circuit Operations
VFR pilots often conduct repeated training circuits within a control zone. These circuits include:
Touch-and-Go
- The aircraft lands briefly and immediately takes off again.
- Treated as a landing until touchdown, then as a departure.
Low Approach
- The aircraft flies over the runway at a low altitude without touching down.
- Considered an approach until threshold, then a departure.
Note: ATC must provide routing instructions before issuing clearance for touch-and-go or low approaches.
VFR Traffic Information in Controlled Airspace
In Class D airspace, VFR flights are not separated by ATC but must receive traffic advisories:
- VFR-VFR Traffic Information
- Example: “XYZ123, traffic 2 o’clock, 3 miles, Cessna 172, 2000 feet, in circuit.”
- VFR-IFR Traffic Information
- Example: “XYZ123, traffic on final, Boeing 737, 4 NM, expect wake turbulence.”
Situations Where Traffic Information is Mandatory:
- IFR aircraft on final approach (within 4NM of runway).
- VFR departures and arrivals on the same route.
- VFR aircraft following another VFR aircraft at a higher speed.
- IFR departures near VFR circuit traffic.
If ATC cannot ensure traffic advisories, they may deny VFR entry or instruct aircraft to land or exit controlled airspace.
Traffic circuit
VFR Traffic Circuit Operations
A traffic circuit (or traffic pattern) is a standard flight path used by aircraft operating at uncontrolled airfields and some controlled aerodromes. The circuit provides a structured approach and departure system that enhances safety, situational awareness, and collision avoidance. It is also an essential training tool for pilots, allowing them to practice takeoffs and landings efficiently.
Traffic circuits are typically flown at 1000 feet above ground level (AGL) unless otherwise specified. At major controlled airports, standard circuits may not be published, and ATC provides instructions for circuit operations based on traffic conditions.
Circuit Components
The traffic circuit consists of the following key segments:
Departure (Upwind)
- Aircraft climbs out after takeoff, completing essential post-takeoff procedures (e.g., retracting gear/flaps, setting climb power).
- ATC may issue specific departure instructions based on airspace constraints.
Crosswind
- After reaching a safe altitude, the aircraft turns 90 degrees to the crosswind leg.
- By this point, the aircraft should be nearing the circuit altitude.
Downwind
- The aircraft flies parallel to the runway but in the opposite direction of landing.
- This is where position reports are typically made to inform ATC and other traffic of the aircraft’s location.
- Pilots conduct pre-landing checks, adjusting speed and altitude as needed.
Base Leg
- A 90-degree turn positions the aircraft perpendicular to the runway.
- Descent is initiated, and the final landing configuration (flaps, gear) is established.
- Pilots confirm approach clearance (if required) before turning onto final.
Final Approach
- The aircraft aligns with the runway centerline and descends for landing.
- ATC provides final wind and clearance information at controlled aerodromes.
- Minimal radio transmissions should occur at this stage to allow the pilot to focus on landing.
Standard traffic circuits are typically flown with left turns unless otherwise specified. If right-hand circuits are in use, all references should include “right” (e.g., right downwind, right base).

Taxi to Apron | XYZ123, taxi to Apron 2 via D and I. | XYZ123, roulez au parking 2 via D et I. |
Right-Hand Circuits & Special Considerations
- Standard circuits use left turns unless otherwise published.
- If a right-hand circuit is required, ATC must explicitly instruct the pilot (e.g., “join right downwind”).
- Turns after takeoff, especially right turns, require explicit ATC clearance to prevent airspace conflicts.
E.g. If departing from runway 32 via an eastern exit route, ATC should approve a right turn to avoid a long left turn over the airport.
Circuit Operations at Controlled Airports
At larger controlled airports, standard traffic circuits may not exist due to:
- The variety of aircraft types (from small aircraft to large airliners).
- The need for flexible ATC separation.
At these airports, pilots may be given customized departure and arrival instructions instead of following a published circuit.
Traffic Circuit Delays & ATC Management
When integrating VFR circuits into busy airspace, ATC may use various delay techniques:
-
Extending the Downwind
- ATC instructs pilots to continue downwind past the normal turning point.
- Used to create spacing for IFR arrivals or departing traffic.
-
360-Degree Orbits
- A pilot may be instructed to orbit at a safe location within the circuit.
- Typically used when ATC needs additional time to manage runway operations.
-
Holding at a Reporting Point
- ATC may direct pilots to hold at a designated reporting point before joining the circuit.
- Ensures orderly sequencing of multiple VFR arrivals.
If a pilot is cleared for one segment of a circuit (e.g., downwind), they automatically continue through base and final unless further ATC instructions are given. Controllers must use delaying techniques proactively if separation is required.
Delay techniques
VFR Holding
Air Traffic Control (ATC) may require VFR aircraft to hold over a specific area due to congestion or sequencing issues. The term "ORBIT" is used to instruct aircraft to circle a designated point until further notice. Pilots must remain in the orbit until cleared to continue.
ATC Holding Instructions Format:
[Aircraft Call Sign], ORBIT [Direction] OF [Location], [Turn Direction], [Expected Duration/Number of Orbits].
Example:
Cessna 45X, ORBIT EAST OF CITY BRIDGE, LEFT TURNS, EXPECT FURTHER INSTRUCTIONS IN 5 MINUTES.
In this case, the aircraft must maintain left turns east of the City Bridge until ATC provides further instructions.
ATC Holding Instructions | English | French |
---|---|---|
N123X, orbit left. | Orbit left. | Orbitez à gauche. |
N123X, orbit abeam threshold. | Orbit abeam threshold. | Orbitez au seuil de piste. |
N123X, make a right 360. | Make a right three-sixty. | Effectuez un trois-six zéro à droite. |
Remaining Outside Controlled Airspace
Before entering Class D airspace, VFR aircraft must establish communication with ATC. Due to traffic congestion, ATC may instruct the pilot to remain outside the controlled airspace until further notice.
ATC Instruction Example:
[Aircraft Call Sign], REMAIN OUTSIDE CLASS D AIRSPACE, STANDBY.
Example:
Skyhawk 82B, REMAIN OUTSIDE CLASS D AIRSPACE, STANDBY.
The pilot must remain clear of Class D airspace and await further instructions from ATC.
ATC Instruction | English | French |
---|---|---|
Remain outside Class D airspace. | Remain outside Class D airspace. | Restez en dehors de l’espace aérien de classe D. |
Delaying Techniques for VFR Aircraft
VFR aircraft generally operate at lower speeds compared to commercial traffic. To ensure efficient traffic flow, ATC may need to create adequate spacing between VFR and IFR arrivals. A gap of 7 to 9 NM is typically required between a slow VFR aircraft and faster IFR traffic on approach.
To optimize sequencing and minimize delays, ATC can employ several delaying techniques.
Orbits (360-Degree Turns)
Orbits are used to keep VFR traffic within a confined area while awaiting clearance to continue. These are particularly useful when delaying traffic near the airport without significantly affecting approach sequencing.
- A standard 360-degree turn takes approximately 2 minutes at a standard rate of 3° per second.
Orbit Instructions | English | French |
---|---|---|
N123X, orbit left. | Orbit left. | Orbitez à gauche. |
N123X, orbit abeam threshold. | Orbit abeam threshold. | Orbitez au seuil de piste. |
N123X, make a right 360. | Make a right three-sixty. | Effectuez un trois-six zéro à droite. |
Landing Sequence
If multiple aircraft are approaching the airfield, ATC may issue landing sequence instructions to VFR aircraft. The pilot is assigned a position in sequence and is responsible for maintaining safe spacing from the preceding aircraft.
Landing Sequence Instructions | English | French |
---|---|---|
N567P, number two, follow Boeing 737, 4 NM final, report traffic in sight. | Number two, follow Boeing 737, 4 NM final, report traffic in sight. | Numéro deux, suivez le Boeing 737, finale 4 NM, signalez le trafic en vue. |
N432B, number three, follow Cessna 172 on downwind. | Number three, follow Cessna 172 on downwind. | Numéro trois, suivez le Cessna 172 en vent arrière. |
Extended Downwind
Extending downwind is another delaying technique where a VFR aircraft remains on downwind leg longer than usual before turning onto base and final approach.
- This technique is useful for spacing VFR aircraft between IFR arrivals.
- A longer downwind leg requires larger gaps between IFR traffic.
Extended Downwind Instructions | English | French |
---|---|---|
N123B, extend downwind. | Extend downwind. | Prolongez vent arrière. |
N567X, extend downwind, I will call your base. | Extend downwind, I will call your base. | Prolongez vent arrière, j’appellerai votre base. |
Summary of ATC Delaying Techniques
Technique | Purpose | Example Instruction (English/French) |
---|---|---|
Orbits | Keep VFR traffic within a defined area. | Cessna 34X, ORBIT RIGHT OVER HILLTOP. / Cessna 34X, ORBITEZ À DROITE AU-DESSUS DE LA COLLINE. |
Landing Sequence | Assign landing order and spacing. | Cessna 34X, NUMBER TWO, FOLLOW 737, REPORT TRAFFIC IN SIGHT. / Cessna 34X, NUMÉRO DEUX, SUIVEZ 737, SIGNALEZ LE TRAFIC EN VUE. |
Extended Downwind | Delay VFR approach by increasing downwind length. | Cessna 34X, EXTEND DOWNWIND, I WILL CALL YOUR BASE. / Cessna 34X, PROLONGEZ VENT ARRIÈRE, J’APPELLERAI VOTRE BASE. |
Practice approach/area
Practice Area Position Report
A good practice area position report ensures that other pilots operating in the same vicinity can accurately visualize your location and movements.
Best Practices for Position Reporting:
- Before entering a practice area, inquire whether it is already occupied.
- Once inside, define the boundaries of your operational space using easily recognizable landmarks.
- Specify your altitude or altitude block.
- Only make subsequent reports when necessary, such as:
- When another aircraft is approaching or moving into an adjacent area.
- When you are changing location or altitude.
Avoid unnecessary radio calls to prevent frequency congestion and reduce distractions for pilots receiving instructions.
Practice Approach VFR
The VFR Practice Approach allows pilots to practice different approach procedures under visual flight conditions.
- If the practice approach is conducted within Class D airspace (CTR), the tower is responsible for handling the request.
- If the approach begins within Class C or D, the approach or center controller is responsible.
Important Considerations:
- The practice approach must remain under VFR conditions.
- The pilot must comply with VMC minima.
- All instructions from ATC are recommendations only.
Standard ATC Phraseology:
Language | Instruction |
---|---|
French | "Indicatif d'appel, maintenez VMC, toutes les instructions d'altitude et de cap sont des recommandations." |
English | "Callsign, maintain VMC, all altitude and heading instructions are recommendations." |
Vectoring Considerations
- If traffic volume is high, vector the aircraft closer to final (5-7 NM).
- If time allows, ask the pilot how many miles of final approach they prefer.
Alternative: Instead of using heading recommendations, pilots may also be guided using traffic circuit sections leading to final approach.

Arrivals/Approach
Coordination and Entry into Controlled Airspace
When a VFR aircraft is approaching controlled airspace (CTR), the responsible ATS unit must coordinate its arrival before handing it over. If the airspace is congested, ATC may request adjustments to the aircraft’s altitude or route or, if necessary, deny entry to ensure safe traffic management.
For VFR flights arriving from uncontrolled airspace, ATC should initiate contact with the pilot approximately 2-5 minutes before they enter controlled airspace by sending a .contactme message or other suitable notification.
Establishing Contact with a VFR Arrival
Upon initial contact, controllers must confirm the intentions of the pilot, such as:
- Full-stop landing
- Touch-and-go
- Low approach
- Other special requests
If a squawk code has not been assigned yet, ATC should provide one at this stage.
VFR Arrival Clearances
For VFR aircraft arriving via designated VFR routes, a route clearance should include:
- The assigned VFR route
- The runway in use
- The QNH
- A squawk code (if needed)
- A request to report passing the last VRP (Visual Reporting Point)
Example Phraseology:
[CALLSIGN], follow route X for runway XX, [QNH], [SQUAWK if necessary], report passing [REPORTING POINT].
Example:
Cessna 45X, follow route 6 for runway 01, QNH 1005, report passing the Church.
For arrivals not using a VFR route, ATC should provide an appropriate clearance that includes:
- Routing instructions (e.g., direct entry, overhead join, downwind join, etc.)
- Assigned altitude
- Local QNH
- Squawk code (if required)
Example Phraseology:
[CALLSIGN], [ROUTING], [ALT], [QNH], [SQUAWK*].
(*Squawk may be omitted if already assigned.)
Traffic Management on Arrival
Before being cleared to land, VFR aircraft must establish initial contact with the appropriate controller. In high-traffic situations, ATC may instruct pilots to hold outside the airspace or orbit at a specific point until sequencing permits entry.
Once inside the circuit, ATC assigns a sequence number, which informs the pilot about their position in the landing order. For example:
"You are number three to land."
This indicates that two aircraft are ahead, and the pilot must maintain appropriate separation until cleared for final approach.
By following these structured VFR arrival procedures, controllers ensure a safe, efficient, and predictable flow of traffic into controlled airspace.
Transits & Other Flights
A VFR transit occurs when an aircraft enters a control zone (CTR) and crosses it without intending to land at any airport within the zone.
VFR transits are typically conducted along designated VFR routes, exit/entry points, or directly on course, subject to ATC approval and traffic conditions.
Handling a Single VFR Transit Aircraft
When a single VFR aircraft transits a CTR:
- The aircraft usually enters via or near a published VFR entry point.
- The pilot should establish contact with ATC at least 2 minutes before reaching the entry point.
- The controller issues transit instructions, ensuring traffic separation.
Example Phraseology
🛩️ Pilot: Tower, Cessna 172, 3000ft, 2 minutes to W, request transit to S, FGJNG.
📡 ATC: FGJNG, transit W, WA, overhead the field, and S, altitude 2000 feet, report WA.
🛩️ Pilot: Transiting W, WA, overhead the field, and S, altitude 2000 feet, will report WA, FGJNG.
Transit Outside VFR Reporting Points
In some cases, pilots may request transit outside of designated VFR entry/exit points to shorten their route. The controller may approve or deny this request based on factors such as:
- Weather conditions (Special VFR requirements)
- Night operations
- Existing traffic in the control zone
- Activity in the aerodrome circuit
Example Phraseology
📡 ATC: FGJEL, transit WA, exit south-west of CTR, altitude 2000 feet, report leaving the control zone.
📡 ATC: FGJNG, transit direct S, altitude 2000 feet, report leaving the control zone.
Handling Multiple VFR Transits
When multiple VFR aircraft are transiting at the same time, potential conflicts may arise. The controller must:
- Provide traffic information to both aircraft.
- Ensure pilots maintain visual separation.
Example Phraseology
📡 ATC: FGJNG, traffic, Cessna 172, same altitude at your 9 o’clock, 4 miles, will cross your route left to right around WA, report in sight.
🛩️ Pilot: Traffic in sight, FGJNG.📡 ATC: FGJEL, traffic, Cessna 172, same altitude at your 3 o’clock, 4 miles, will cross your route right to left around WA, report in sight.
🛩️ Pilot: Traffic in sight, FGJEL.
After acknowledging traffic, pilots are responsible for adjusting their heading and altitude as needed while maintaining visual separation.
VFR Transit and Aerodrome Circuit Operations
When a VFR transit aircraft crosses near an active aerodrome circuit, ATC should:
- Assign a higher altitude (typically 500-1000 feet above the circuit) to ensure separation.
- Provide traffic information to both transit and circuit aircraft.
Example Phraseology
🛩️ Pilot: Tower, Cessna 172, 1000ft, 2 minutes to S, request transit to N, FGJEL.
📡 ATC: FGJEL, transit S, overhead the field, and N, altitude 1500 feet, report N.
🛩️ Pilot: Transiting S, overhead the field, and N, altitude 1500 feet, will report N, FGJEL.📡 ATC: FGJNG, traffic, Cessna 172 at your 12 o’clock, from S to overhead the field, 500 feet above.
🛩️ Pilot: Traffic in sight, FGJNG.📡 ATC: FGJEL, traffic, Cessna 172 at your 12 o’clock, right-hand downwind runway 36, 500 feet below.
🛩️ Pilot: Traffic in sight, FGJEL.
Transit aircraft should avoid directly overflying the runway at low altitude, maintaining an offset to free the runway axis for arriving and departing traffic.
VFR Transit and IFR on Final Approach
When a VFR transit aircraft crosses near an IFR arrival on final approach, ATC should:
- Assign a transit altitude higher than the circuit altitude.
- Avoid runway axis crossings at low altitude.
- Provide traffic information to both aircraft.
VFR Contact
🛩️ Pilot: Tower, Cessna 172, 1000ft, at W, request transit to S, FGJEL.
📡 ATC: FGJEL, transit WA, overhead the field, then right-hand downwind runway 36 and S, altitude 2000 feet, report S.
🛩️ Pilot: Transiting WA, overhead the field, then right-hand downwind and S, altitude 2000 feet, will report S.
IFR Arrival Contact
✈️ Pilot: Tower, on final runway 36, TUI411.
📡 ATC: TUI411, runway 36 cleared to land, winds 340° 6KT, traffic left to right at 2000ft, will cross overhead the field.
✈️ Pilot: Runway 36 cleared to land, traffic in sight, TUI411.
Traffic Information to VFR Aircraft
📡 ATC: FGJEL, traffic information Boeing 757 on final runway 36, report traffic in sight.
🛩️ Pilot: Traffic in sight, FGJEL.
The VFR aircraft is responsible for maintaining safe separation from the IFR traffic, except in Class C airspace, where ATC must ensure separation.
If a runway axis crossing is necessary, ATC should consider possible IFR go-arounds. The transit should either be expedited or delayed until the IFR traffic has landed.
Summary of VFR Transit Best Practices
Scenario | ATC Best Practice |
---|---|
Single VFR Transit | Assign a defined VFR route or direct clearance with altitude. |
Multiple VFR Transits | Issue traffic information and ensure pilots maintain visual separation. |
Transit near Aerodrome Circuit | Maintain 500-1000 feet separation from circuit aircraft. |
Transit near IFR Final Approach | Assign higher altitudes, provide traffic information, and avoid low-altitude runway crossings. |
VFR in Airspace C/D
When a VFR aircraft requests to cross Class C or Class D airspace, the following conditions must be met:
- Aircraft Identification: The aircraft must be assigned a squawk code.
- Routing & Altitude Considerations: The aircraft's flight path should avoid direct passage through arrival and departure sectors.
- Clearance Requirements: The pilot must receive explicit entry and exit clearances for the controlled airspace.
Separation Requirements:
- Class C: IFR-VFR separation is required. VFR flights receive traffic information about IFR and other VFR aircraft. Traffic avoidance is provided upon request.
- Class D: Traffic information is provided to both IFR and VFR flights; separation is not provided for VFR aircraft.
Traffic Management in the CTR
Managing traffic within the Control Zone (CTR) is a routine task for ATC. Although the CTR may appear small on radar, it provides ample space for maneuvering. By issuing timely and accurate traffic information, further ATC intervention is rarely needed.
Opposing-direction VFR traffic may be cleared at the same altitude (e.g., "Maintain 2000 feet or below VFR") if appropriate traffic information is issued to ensure situational awareness.
While no minimum vertical separation is mandated when separation is not required, a 400-500 ft margin is recommended where feasible. Single-engine aircraft should not be forced too low due to emergency landing considerations. Always consider terrain and weather conditions when assigning altitude restrictions.
Crossing an airport overhead or extended centerline should be managed similarly to a runway crossing on the ground. Aircraft in takeoff and landing phases are in high-workload situations, making their trajectories less predictable. To enhance situational awareness, controllers should use "Report in sight" before issuing crossing clearances.
Overhead Crossings
If circuit traffic is light, directing aircraft to cross overhead simplifies coordination, keeping them above wake turbulence and on a predictable flight path. If circuits are busy, alternative routes should be used:
CNBOB, maintain VFR between 1500 and 2000 feet, cross runway 35 overhead direct KOSAD.
CNBOB, route south, remain east of the centerline and right-hand circuit for runway 35.
Approach Path Crossings
Crossing near the extended centerline further from the airport requires additional caution:
CNBOB, traffic A320 five miles final, report in sight.
CNBOB, cross runway 35 centerline behind the A320. Caution wake turbulence.
Notify the landing aircraft:
RAM123, traffic information: Light aircraft three miles east, crossing centerline behind you. They have you in sight.
Operations Below the Glide Path
For aircraft needing to cross beyond 4-5NM from the airport, staying below the approach path may be an option:
CNBOB, cleared to operate south of Berrechid, five miles out or greater, maintain 1700 feet or below VFR. Traffic: continuous IFR arrivals on the ILS 35, caution wake turbulence.
Notify IFR arrivals:
RAM123, traffic information: Light aircraft operating at least 500 feet below the glide path, continue approach, runway 35L cleared to land.
Maintaining a 500 ft buffer below the glide path generally prevents TCAS Resolution Advisories (RA). However, pilots should receive frequent traffic updates to ensure situational awareness and a safe operating environment.

Flight Plans
Filing a VFR Flight Plan
A VFR flight plan is required for:
- All VFR flights entering controlled airspace (including departures and arrivals at controlled aerodromes).
- All VFR flights at night.
VFR flight plans are filed using ICAO-standard flight plan submission forms. Alternatively, for flights operating only within a specific terminal control area (TMA), pilots may file their flight plans via voice.
Required Information for a VFR Flight Plan
The following details are mandatory when filing a VFR flight plan:
- Callsign (aircraft registration or designated flight ID)
- Route of flight (departure, route, and destination)
- Estimated enroute time
- Endurance (fuel endurance in hours and minutes)
- Pilot-in-command (PIC) name and number of persons on board (POB)
Example of Filing a VFR Flight Plan via Voice
A pilot may file their flight plan verbally when operating within a designated terminal area.
Example Phraseology:
🧑✈️ (TF-)FFL, requesting VFR flight plan: Departure [Airport], enroute to [Destination] via [Route/Area], estimated time enroute [EET], endurance [Fuel], PIC [Pilot Name], [Number of Persons on Board].
Example:
🧑✈️ Alpha Bravo Charlie, requesting VFR flight plan: Departure Casablanca, enroute to Marrakech via coastal route, estimated time enroute 1 hour 20 minutes, endurance 4 hours, PIC John Doe, 2 persons on board.
Entering a Flight Plan in ATC Systems
For controllers, flight plans filed via voice can be manually entered into ATC systems such as Euroscope or other radar client software.
Flight Plan Entry Steps in Euroscope:
- Select the aircraft: Click on the callsign or type it and press
NUMPAD +
. - Open the flight plan menu: Press
F1
. - Create a flight plan: Press
A
, thenNUMPAD +
. - Alternatively, use specific functions in TopSky or other ATC plugins (refer to the user manual for details).
SVFR and NVFR
Night VFR (NVFR) refers to visual flight operations conducted at night. The applicable period is from the beginning of civil twilight to the end of civil dawn. Accurate timing for these periods can be referenced in published tables.
Key Considerations for Controllers
Controllers managing NVFR traffic must be aware of two primary aspects:
Continuous Radio Communication Requirement
For safety reasons, NVFR pilots must maintain continuous two-way radio communication throughout their flight.
- NVFR aircraft departing a controlled aerodrome must be handed off from the tower controller to the appropriate radar (approach or center) controller.
- NVFR aircraft departing from an uncontrolled aerodrome (AFIS station) must self-transfer to the relevant radar frequency.
- Unlike standard VFR flights, pilots must not be allowed to leave the frequency when reaching the outer reporting point. Instead, they must be transferred to the appropriate radar controller.
Flight Plan Requirement for NVFR Flights
- A flight plan is mandatory when an NVFR aircraft leaves the immediate vicinity of the departure aerodrome.
- Pilots are responsible for ensuring their NVFR flight plan is filed and activated before departure.
Myth: NVFR Clearance
A common misconception is that a “Night VFR clearance” exists, similar to a Special VFR (SVFR) clearance.
Clarification:
- There is no separate NVFR clearance.
- NVFR flights follow standard VFR entry, exit, and routing procedures, with the additional requirement of continuous radio contact and a filed flight plan when leaving the airport vicinity.
Phraseology Example
Handoff from Tower to Radar Controller
[CALLSIGN], CONTACT [RADAR UNIT] ON [FREQUENCY].
Example:
Cessna 45X, contact Approach on 123.450.
Flight Plan Confirmation
[CALLSIGN], CONFIRM FLIGHT PLAN FILED FOR NIGHT VFR.
Example:
Piper 67Y, confirm flight plan filed for Night VFR.
Operational Summary
Requirement | Standard VFR | Night VFR (NVFR) |
---|---|---|
Continuous Radio Contact | Not always required | Mandatory |
Flight Plan Required | Only for cross-border flights | Required when leaving aerodrome vicinity |
Handoff to Radar | Not always required | Mandatory |
Clearance Type | VFR clearance | No separate NVFR clearance |
By adhering to these procedures, controllers can ensure safe and efficient handling of NVFR operations, maintaining proper separation and communication with all aircraft operating under night visual flight rules.
Helicopters
Helicopters operate under Visual Flight Rules (VFR) and, in some cases, Instrument Flight Rules (IFR), though IFR operations are less common. While they follow many of the same procedures as fixed-wing aircraft, there are key differences due to their ability to hover, air-taxi, and land at non-airport locations.
Controller Responsibilities for Helicopter Operations
- VFR Arrivals/Departures: Handled similarly to fixed-wing aircraft.
- Traffic Patterns & Practice Approaches: Managed with consideration for helicopter-specific maneuvering capabilities.
- Operational Flexibility: Helicopters may request direct routing, off-field landings, and alternative taxi procedures.
Helicopter Callsigns
Helicopter callsigns vary based on their operator and purpose:
- Private & Corporate Flights: Use standard registration callsigns.
- Rescue Helicopters: Use specialized callsigns and may add "RESCUE" when operating on a priority mission.
- Police Helicopters: Use law enforcement identifiers.
Ground Movements & Air-Taxiing
Unlike fixed-wing aircraft, most helicopters do not taxi conventionally. Instead, they air-taxi at approximately 3 meters (10 feet) AGL.
- Controllers should issue "air-taxi" clearances instead of standard taxi instructions.
- Some helicopters have wheels and may perform limited ground taxiing.
- Helicopters can depart from intersections, helipads, or designated airport positions, subject to clearance.
Example Phraseology
Scenario | French | English |
---|---|---|
Request for Air-Taxi | Tour, F-HABC, demande de déplacement en vol stationnaire | Tower, F-HABC, request air-taxi |
Air-Taxi Clearance | F-HABC, tour, déplacement en vol stationnaire vers le point d'attente piste 18 intersection S via Y7, Y5 et S, rappelez prêt au départ. | F-HABC, Tower, air-taxi to holding point runway 18 intersection S via Y7, Y5, and S, report ready. |
Helicopter Takeoff & Landing Procedures
Helipad Takeoff & Landing
Scenario | French | English |
---|---|---|
Cleared for Takeoff from a Helipad | F-HABC, vent 210 degrés, 5 nœuds, autorisé au décollage depuis l'hélipad. | F-HABC, wind 210 degrees, 5 knots, cleared for takeoff from helipad. |
Cleared to Land at a Helipad | F-HABC, vent 210 degrés, 5 nœuds, autorisé à l'atterrissage sur l'hélipad. | F-HABC, wind 210 degrees, 5 knots, cleared to land helipad. |
Runway Takeoff & Landing Considerations
- Helicopters may depart vertically or use rolling takeoff techniques.
- They may land on designated helicopter landing sites or a runway, subject to clearance.
- Standard runway separation applies to helicopters using runways.
CTR Crossing & Direct Routing Requests
Helicopters often request direct routes or control zone (CTR) crossings due to their operational flexibility.
Example Phraseology
Scenario | French | English |
---|---|---|
Request for CTR Crossing | Tour, F-HABC, demande traversée du CTR pour destination Lyon. | Tower, F-HABC, request to cross CTR en route to Lyon. |
CTR Crossing Approval | F-HABC, QNH 1006, pistes en service 25 et 18, traversez comme demandé. | F-HABC, QNH 1006, runways 25 and 18, proceed as requested. |
Traffic Advisory | F-HABC, trafic, Boeing 737 en finale 3 NM piste 25L, signalez en vue. | F-HABC, traffic, Boeing 737 on 3-mile final runway 25L, report traffic in sight. |
Crossing Instruction | F-HABC, croisez derrière le trafic mentionné au sud, attention aux turbulences de sillage. | F-HABC, cross behind mentioned traffic to the south, caution wake turbulence. |
Off-Airport Landings & Takeoffs
General Considerations
- Helicopters may request off-airport landings for rescue, police, or private operations.
- Controllers do not issue landing/takeoff clearances for off-field operations but provide flight following if necessary.
Example Phraseology
Scenario | French | English |
---|---|---|
Off-Field Landing Request | F-HABC, approche de l'hôpital, demande de quitter la fréquence. | F-HABC, approaching hospital, request to leave frequency. |
Frequency Change Approval | F-HABC, (vent 210 degrés, 17 nœuds), fréquence quittée approuvée, rappelez avant de redécoller.* | F-HABC, (wind 210 degrees, 17 knots), approved to leave frequency, report prior airborne again.* |
Scenario | French | English |
---|---|---|
Off-Field Takeoff Request | Tour, F-HABC, à nouveau en vol à Casablanca, demande route directe vers l’hôpital. | Tower, F-HABC, airborne again at Casablanca, request direct route to hospital. |
Routing Approval | F-HABC, QNH 1006, pistes en service 25 et 18, poursuivez comme demandé. | F-HABC, QNH 1006, runways 25 and 18, proceed as requested. |
Priority Missions & ATC Considerations
Helicopters engaged in medical, law enforcement, or emergency response flights may request priority handling. While ATC should accommodate direct routing requests when feasible, priority cannot be demanded under standard procedures.
- Emergency flights may require direct routing through airport approach paths.
- Holding or delay vectors may be issued if required for traffic sequencing.
- Coordination with pilots ensures efficient integration into controlled airspace.
Note: On VATSIM, per the Code of Conduct, no flight has an automatic right to priority. Controllers may accommodate priority requests but are not obligated to do so if it disrupts other operations.
