CHANGING THE AIRSPEED REFERENCE
The Airspeed Reference (shown in both the AFCS Status Box and above the Airspeed Indicator) may be
adjusted by:
• Using the NOSE UP/DN Wheel
• Pressing the CWS Button, hand-flying the aircraft to attain a new Airspeed Reference, then releasing the
CWS Button
If the Selected Altitude is reached during CWS maneuvering, the Altitude Reference is not changed.
NOTE:
To adjust the Altitude Reference in this case, the CWS Button must be pressed again after the Selected
Altitude is reached.
During climb, the pilot must select the Airspeed Reference (IAS or Mach), automatic switching does not
occur. For descent, if Mach airspeed reference is selected (above 16,000 ft) the aircraft descends in Mach
until the indicated airspeed reaches 220 KIAS, at which point the airspeed reference automatically switches
to IAS. The system determines aircraft climb or descent by the relationship between the current and Selected
altitudes.
Airspeed Reference units can be manually toggled between IAS and Mach units using the SPD Key. When
the FLC Airspeed Reference is displayed in Mach, the Airspeed Reference Bug is displayed on the Airspeed
Indicator at the IAS corresponding to the selected Mach target speed and the current Mach number is shown
only in the AFCS Status Box.
