LNAV and TRACK

Arm LNAV

Use a simple departure route and record the lateral FMA before and after takeoff. ^[37]

With a suitable route and LNAV armed, observe the transition while maintaining control.

LNAV capture

Read ROLL, TRACK and LNAV indications and compare the actual path with the departure.

FSS describes armed LNAV engagement after passing 200 ft in climb; TRACK is a different lateral mode.

Lateral mode

Check the active lateral mode, route and aircraft position. If the turn is not what you expect, maintain a safe path.
