GM1 ADR.OPS.B.026(d) Authorisation of vehicles ED Decision 2021/003/R VEHICLE CALL SIGNS The use of similar call signs may lead to call sign confusion, which is one of the factors associated with runway incursions. To avoid call sign confusion, when assigning a call sign to a vehicle, careful consideration needs to be given to the call signs used by aircraft operating at the aerodrome, as well as the call signs of other vehicles. Ways to reduce the possibility of call sign confusion include: (a) use of unique numbers or identification call signs for each vehicle; and (b) use of call signs which are appropriate to the function of the vehicle (e.g. ‘Operations’, ‘Fire’). Where more than one vehicle is used in the same function, then a numbering policy may be used, such that the call sign is followed by a number, e.g. ‘Operations 1’. At aerodromes where the number of vehicles and the aircraft traffic is high, before assigning a call sign to a vehicle, it is recommended that the aerodrome operator, apart from the coordination with the air traffic services provider, consults also the other organisations operating vehicles at the aerodrome. As soon as a call sign is assigned to a vehicle, this needs to be known to at least the air traffic services provider.
