AMBER IAS MISCOMP MESSAGE COMES ON
1. Pilot and Copilot Airspeed . . . . . . . . . . . . . . . . . . . . COMPARE
(with standby airspeed indicator)
2. PITOT/STATIC HEAT Switch. . . . . . . . . . . . . . . . . . CHECK ON
(if clouds or visible moisture present)
WARNING
The standby airspeed indicator uses the same
pitot-static sources as the pilot’s side air data
computer (ADC1). Do not use standby airspeed
indicator as sole source in determining correct
airspeed.
IF COPILOT PFD AND STANDBY AIRSPEED AGREE (PILOT PFD

IF ALTITUDES AGREE
4. Airspeed . . . . . . . . . 120 KIAS MINIMUM (on slowest indicator)
5. Monitor all three airspeed indicators during changes in power
setting or altitude to determine which indicators are inaccurate.
Indications of inaccurate airspeed include:
a.
No change in indicated airspeed when power changed and
altitude maintained.
b. Indicated airspeed increases when climbing or decreases
when descending.
6. Use SENSOR reversion to select most accurate ADC on the
affected PFD.
7. Airspeed . . . . . . . . . . . . . . . . . . . RESUME NORMAL SPEEDS
IF ALTITUDES DO NOT AGREE
4. Refer to AMBER ALT MISCOMP MESSAGE COMES ON
procedure to determine most accurate ADC.
