AUTOMATIC FLIGHT CONTROL SYSTEM
FLIGHT LEVEL CHANGE MODE (FLC)
NOTE: The Selected Altitude should be set before selecting Flight Level Change Mode.
Flight Level Change Mode is selected by pressing the FLC Key. This mode acquires and maintains the
Airspeed Reference (in IAS or Mach) while climbing or descending to the Selected Altitude (shown above
the Altimeter). When Flight Level Change Mode is active, the flight director continuously monitors Selected
Altitude, airspeed, Mach, and altitude.
The Airspeed Reference is set to the current airspeed upon mode activation. Flight Level Change Mode is
indicated by a green ‘FLC’ annunciation beside the Airspeed Reference in the AFCS Status Box. The Airspeed
Reference is also displayed directly above the Airspeed Indicator, along with a bug corresponding to the Airspeed
Reference along the tape.
Engine power must be adjusted to allow the autopilot to fly the aircraft at a pitch attitude corresponding
to the desired flight profile (climb or descent) while maintaining the Airspeed Reference. The flight director
maintains the current altitude until either engine power or the Airspeed Reference are adjusted and does not
allow the aircraft to climb or descend away from the Selected Altitude.
