04 / TAKEOFF AND CLIMB
Takeoff and climb guidance
Before takeoff, press TOGA on a thrust lever. The PFD FMA should show TO and ROLL. Arm A/T separately; the FSS procedure guide includes the TOGA action, but its online normal checklist omits it [9].
FSS says VNAV arms the FMS climb mode on the ground. The default capture is 800 ft above field elevation; DEP LIM sets the value [24].
An armed mode is waiting to engage. Watch for the mode to become active and check the aircraft response.
FSS lists 400 ft as the minimum autopilot engagement height; the cited text does not state the height reference [10].
