AFCS

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.
