Takeoff mode and speed

FSS says TO mode initially commands the calculated pitch angle. For the subsequent airborne guidance with both engines operating, it lists V2 + 10 kt and describes a transition when IAS is above the speed target. It also lists pitch and speed limits. Follow the actual flight-director command and check the FMA rather than assuming that liftoff alone changes the guidance. FSS vertical modes ^[38] · TO mode discussion ^[225].

For one engine inoperative, FSS describes the subsequent airborne speed target as V2 if the failure occurs below V2, the speed at failure if it occurs between V2 and V2 + 10, or V2 + 10 if it occurs above V2 + 10. FSS states that the speed-guidance transition requires the aircraft to be airborne and IAS to exceed the target. The page also lists pitch and speed limits. This is TO-mode guidance, not a complete engine-failure procedure. FSS vertical modes ^[38].

Before taxi

Enter the calculated takeoff data and check that TO pitch is available. A dashed value means required information is missing according to FSS.

Before applying thrust

Set up the intended takeoff modes and verify the annunciations. Note the calculated V-speeds and the planned acceleration height.

On the runway

Monitor thrust, airspeed and aircraft response. Rotate at the calculated VR and follow the guidance with appropriate aircraft control.

After liftoff

Watch speed, pitch and the active vertical mode. Guidance changes depend on aircraft state; do not treat an isolated target as a command to change configuration.

At the planned transition

When the applicable procedure calls for the next mode, select it and read the FMA. Check whether the target is selected or FMS-managed, and watch the resulting acceleration and climb.

Read the FMA and follow the current flight-director guidance. A speed target is not a command to change configuration. ^[38]
