INDICATED AIRSPEED MODE (IAS)
NOTE:
The Selected Altitude should be set before selecting Indicated Airspeed Mode (IAS).
Indicated Airspeed Mode is selected by pressing the
IAS
Key. This mode acquires and maintains the
Airspeed Reference (IAS) while climbing or descending to the
Selected Altitude (shown above the Altimeter).
When Indicated Airspeed Mode is active, the flight director continuously monitors Selected Altitude, airspeed
and altitude.
The Airspeed Reference is set to the current airspeed upon mode activation. Indicated Airspeed Mode is
indicated by a green ‘IAS’ 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.
