Altitude Management to Maintain Separation

ATC Instructions to Maintain a Level Before Any Change:

• MAINTAIN (level) [TO (significant point)]
• MAINTAIN (level) UNTIL PASSING (significant point)
• MAINTAIN (level) UNTIL (minutes) AFTER PASSING (significant point)
• MAINTAIN (level) UNTIL (time)
• MAINTAIN (level) UNTIL ADVISED BY (name of ATC unit)
• MAINTAIN (level) UNTIL FURTHER ADVISED
• MAINTAIN (level) WHILE IN CONTROLLED AIRSPACE
• MAINTAIN BLOCK (level) TO (level).

Note: The term "MAINTAIN" shall not be used in lieu of "DESCEND" or "CLIMB" when instructing an aircraft to change level.

Separation Instructions

ATC Instructions to Overfly a Significant Point at a Specific Time:

• CROSS (significant point) AT (time) [OR LATER (or OR BEFORE)]
• ADVISE IF ABLE TO CROSS (significant point) AT (time or level)

ATC Instructions for Speed Restrictions During Cruise:

• MAINTAIN MACH (number) [OR GREATER (or OR LESS)] [UNTIL (significant point)]
• DO NOT EXCEED MACH (number)

ATC Instructions for Specific Track to Maintain Separation:

• MAINTAIN TRACK BETWEEN (significant point) AND (significant point). REPORT ESTABLISHED ON THE TRACK
• CONFIRM ESTABLISHED ON THE TRACK BETWEEN (significant point) AND (significant point) [WITH ZERO OFFSET]

Pilot Responses:

• ESTABLISHED ON THE TRACK BETWEEN (significant point) AND (significant point) [WITH ZERO OFFSET]
• ESTABLISHED ON THE TRACK

Used when lateral VOR/GNSS separation confirmation of zero offset is required:

• CONFIRM ZERO OFFSET
• AFFIRM ZERO OFFSET

Track Parallel to the Cleared Route

ATC Instructions for Parallel Track Offsets:

• ADVISE IF ABLE TO PROCEED PARALLEL OFFSET
• PROCEED OFFSET (distance) RIGHT/LEFT OF (route) (track) [CENTRE LINE] [AT (significant point or time)] [UNTIL (significant point or time)]
• CANCEL OFFSET (instructions to rejoin cleared flight route or other information)

Vectoring Instructions

ATC Instructions for Vectoring:

• FLY HEADING (three digits)
• TURN LEFT (or RIGHT) HEADING (three digits) [reason]
• TURN LEFT (or RIGHT) (number of degrees) DEGREES [reason]

Other ATC Instructions in Vectoring Procedures:

• LEAVE (significant point) HEADING (three digits)
• CONTINUE HEADING (three digits)
• CONTINUE PRESENT HEADING
• STOP TURN HEADING (three digits)
• FLY HEADING (three digits), WHEN ABLE PROCEED DIRECT (name) (significant point)
• HEADING IS GOOD

ATC Instructions to Terminate Vectoring Procedure:

• RESUME OWN NAVIGATION (position of aircraft) (specific instructions)
• RESUME OWN NAVIGATION [DIRECT] (significant point) [MAGNETIC TRACK (three digits) DISTANCE (number) KILOMETRES (or MILES)]

ATC Phraseology to Specify Reason for Vectoring:

• DUE TRAFFIC
• FOR SPACING
• FOR DELAY
• FOR DOWNWIND (or BASE, or FINAL)

ATC Instructions for Avoiding Action:

• DO YOU WANT VECTORS?

Pilot Response for Vectoring Guidance:

• REQUEST VECTORS

Holding Clearance

ATC Clearance for Holding Procedures:

• CLEARED (or PROCEED) TO (significant point, name of facility or fix) [MAINTAIN (or CLIMB or DESCEND TO) (level)] HOLD [(direction)] AS PUBLISHED EXPECT APPROACH CLEARANCE (or FURTHER CLEARANCE) AT (time)

Pilot Request for Holding Instructions (If No Published Parameters Exist):

• REQUEST HOLDING INSTRUCTIONS

ATC Clearance for IFR Holding Procedure (Detailed Clearance Required):

• CLEARED (or PROCEED) TO (significant point, name of facility or fix) [MAINTAIN (or CLIMB or DESCEND TO) (level)] HOLD [(direction)] [(specified) RADIAL, COURSE, INBOUND TRACK (three digits) DEGREES] [RIGHT (or LEFT) HAND PATTERN] [OUTBOUND TIME (number) MINUTES] EXPECT APPROACH CLEARANCE (or FURTHER CLEARANCE) AT (time) (additional instructions, if necessary)
• CLEARED TO THE (three digits) RADIAL OF THE (name) VOR AT (distance) DME FIX [MAINTAIN (or CLIMB or DESCEND TO) (level)] HOLD [(direction)] [RIGHT (or LEFT) HAND PATTERN] [OUTBOUND TIME (number) MINUTES] EXPECT APPROACH CLEARANCE (or FURTHER CLEARANCE) AT (time) (additional instructions, if necessary)
• CLEARED TO THE (three digits) RADIAL OF THE (name) VOR AT (distance) DME FIX [MAINTAIN (or CLIMB or DESCEND TO) (level)] HOLD BETWEEN (distance) AND (distance) DME [RIGHT (or LEFT) HAND PATTERN] EXPECT APPROACH CLEARANCE (or FURTHER CLEARANCE) AT (time) (additional instructions, if necessary)
