737 pushback, start and taxi terms

Pushback

The tug or ground crew moves the aircraft while the flight deck monitors brakes and aircraft state.

Headset communication

The defined link between the flight deck and ground crew, with agreed hand signals as backup.

Brakes released and brakes set

Clear, acknowledged callouts at each change of brake status during pushback.

Intake and exhaust hazard area

The danger zone around a running engine that ground staff must stay clear of.

Engine start monitoring

Watching rotation, oil pressure, EGT and fuel flow develop smoothly at the expected stage.

Start abort trigger

Stalled rotation, no oil pressure, EGT near or over the start limit, or no fuel flow.

One engine at a time

Engines are started individually so a problem is found before the next start.

Taxi speed

Chosen for the turn, surface, visibility and traffic, not one fixed number.

Configuration check before runway entry

A spoken two-pilot check that the real configuration matches the takeoff plan.
