FLCH speed control

Select speed target

Select FLCH deliberately and compare the selected speed with the current airspeed.

In a safe practice area, establish a stable climb with an appropriate speed and selected altitude.

FLCH speed control

Monitor pitch, speed trend, thrust and climb rate.

FSS describes selected FLCH as speed controlled by pitch; thrust and the selected altitude affect the resulting trajectory.

FLCH setup

If the path is unsuitable, recover a stable state and check the target, thrust and ALTSEL before repeating.
