Flight Level Change descent:
1) Select Flight Level Change Mode:
a) Using the ALT Knob, set the Selected Altitude to 10,000 feet.
b) Press the FLC Key to activate Flight Level Change Mode. The annunciation ‘FLC’ appears next to the
Airspeed Reference, which defaults to the current aircraft airspeed. Selected Altitude Capture Mode is armed
automatically.
2) Use the NOSE UP/NOSE DN Keys or push the CWS Button while hand-flying the aircraft to adjust the
commanded airspeed while maintaining the same power, or reduce power to allow descent in Flight Level
Change Mode while the autopilot maintains the current airspeed.
3) As the aircraft nears the Selected Altitude, the flight director transitions to Selected Altitude Capture Mode,
indicated by the green ‘ALTS’ annunciation flashing for up to 10 seconds.
The green ‘ALT’ annunciation flashes for up to 10 seconds upon reaching 50 feet from the Selected Altitude; the
autopilot transitions to Altitude Hold Mode and levels the aircraft.
