Climb and cruise

Confirm the climb
Read the active lateral and vertical FMA and the speed source. Check that the aircraft is climbing toward the cleared altitude.
Engage the autopilot when appropriate
Once stable and with the intended modes active, select AP and verify its indication on both PFDs. FSS lists a 400 ft minimum engagement height; check the applicable height reference and aircraft limitations.
Manage speed
Check the FMS or manual target and the actual speed. In FLCH, remember that pitch controls speed while thrust affects the resulting climb.
Check the transition
Set the altimeter reference at the applicable transition altitude and cross-check indications using the current chart and local rules.
Monitor level-off
Watch altitude capture and hold at the selected altitude. Check the resulting thrust and speed.
Review the cruise
Compare position, route, fuel remaining, weather and destination plan. Make deliberate route or altitude changes and verify their effect on the FMA and FMS. [166] [10]
