The Captain must not release parking brakes until the mechanic/
marshaller has given thumbs up signal on the left/ right side, after start checklist is completed and ATC clearance has been obtained.
One person from the ground crew must be designated as marshaller and give thumbs up signal, or at night with marshalling flash light wand and await till the aircraft taxies out.
The Captain will acknowledge the signal of the ground crew by instructing the PM to switch on the taxi / turn off lights.
All actions must be deliberate and unhurried. There should be no hurry to taxi out. It must be ensured that the ground crew has moved away well clear and thumbs up signal has been obtained.
The ground crew on their part must constantly inform the cockpit crew of all the things that are happening down below as an extensive portion below the nose is not visible from the cockpit. If any operation such as disconnecting tow bar etc. is interrupted or delayed, the ground crew must call up on the intercom and inform the Captain. In case of no communication with the ground crew for a reasonable period of time the cockpit crew should also make all attempts to re-establish communication by sounding the horn etc. If there is still no response from the ground, the ground/ apron control should be contacted on R/T. Following ambiguous terminology must never be used.
Parking brake ON/OFF (incorrect) The correct terminology is ; Parking brake set (correct) Parking brake released (correct)
