Takeoff guidance

Green FLCH uses the selected speed and altitude. Magenta FLCH is a VNAV mode and uses an FMS or manual speed target. Read the FMA and check the target before the aircraft accelerates or changes pitch. Departure guidance discussion ^[223].

Set the flight up

Enter and confirm route and performance data. Compare the aircraft load, trim and speeds with the EFB manifest.

Brief the departure

Identify the first lateral instruction, cleared altitude, speed constraints and acceleration plan. Check the relevant chart and current FSS documentation.

Choose your guidance

Decide before takeoff whether to use the documented FMS departure guidance or a selected-mode exercise. Do not assume the two give the same constraint protection.

Check the FMA

Before and after each mode change, read both the active and armed indications. Match the colour to the actual guidance source and look at the selected targets.

Watch the aircraft

Monitor speed, pitch, thrust and altitude. If the response or the mode is unexpected, maintain control and use a known, appropriate mode while you reassess. ^[38]
