Cases of starting and testing aircraft engines at airports and aerodromes in Vietnam

Starting and testing aircraft engines at airports and aerodromes in Vietnam is specified in Article 24 of Circular 29/2021/TT-BGTVT (Effective from January 15, 2022) whereby:

1. Aircraft engines shall be only started or tested at designated positions. Every airport or aerodrome operator shall define the positions where the aircraft engine start-up or testing is permitted (except aprons attached to aircraft maintenance facilities of specific facility operators). The aircraft operators shall move aircrafts to the positions where the aircraft testing is permitted according to regulations laid down by the aircraft or airport operator.

2. The aircraft or airport operator shall establish procedures for ensuring cooperation between units in cases where the aircraft engines are permitted to be started at idle power. Engine start-up at the aircraft stand must be subject to approval by an air traffic controller and notified to the airport or aerodrome operator or representative of the airline. Aircraft maintenance and repair staff shall cooperate with on-duty staff of the airport or aerodrome operator in warning people and vehicles not to move to the areas where the aircraft is started.

3. An aircraft is started at idle power at the aircraft stand only when:

a) The area where ground services are provided and area in front of the aircraft nose are clear of obstacles (except for vehicles and equipment for starting the aircraft engine, maintenance and repair staff and firefighters that are permitted to operate within the aircraft stand but required to be clear of the engine danger area);

b) The tractor is connected to the aircraft for the stands where the tractor is required for pushing and towing operations after starting the aircraft engine.
