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]}
