• ED Decision 2020/008/R found in: ATM/ANS Provision of Services (2017/373) (Mar 2025)

GM2 to AMC16 ATS.TR.210(a)(3) Operation of air traffic control service ED Decision 2020/008/R CANCELLING A TAKE-OFF CLEARANCE FOR DEPARTING AIRCRAFT (a) If a take-off clearance has to be cancelled before the take-off run has commenced, the pilot should be instructed to hold position and to acknowledge the instruction. (b) In certain circumstances, the aerodrome air traffic controller may consider that it is necessary to cancel a take-off clearance after the aircraft has commenced the take-off run. In this event, the pilot should be instructed to stop immediately and to acknowledge the instruction. (c) The cancellation of a take-off clearance after an aircraft has commenced its take-off run should only occur when the aircraft will be in serious and imminent danger should it continue. Air traffic controllers should be aware of the potential for an aircraft to overrun the end of the runway if the take-off is abandoned at a late stage; this is particularly so with large aircraft or those operating close to their performance limit, such as at maximum take-off mass, in high ambient temperatures or when the runway braking action may be adversely affected. Because of this risk, even if a take-off clearance is cancelled, the pilot-in-command may consider it safer to continue the take-off than to attempt to stop the aircraft. (d) Air traffic controllers should also be aware of the possibility that an aircraft that abandons its take-off may suffer overheated brakes or another abnormal situation and should be prepared to declare the appropriate category of emergency or to provide other suitable assistance.
