Arrivals
When flying the arrival, make sure to follow the published altitude restrictions and comply with any ATC instructions. Before arriving at the Initial Approach Fix (IAF), expect the controller to either clear you for the approach, instruct you to hold or vector you. The default approach type for GMMN is the ILS-Z if it is available, but ATC may assign a different approach type based on traffic and operational conditions.
When cleared for the ILS approach from the IAF, it is expected that you follow the published route on the approach chart and descend via the arrival to intercept the glideslope at the appropriate altitude depending on the active configuration. Make sure to comply with any ATC instructions and fly the approach with precision.
