ICE AND RAIN PROTECTION (Continued)
AMBER L, R OR L-R P/S HEAT ANNUNCIATOR COMES
ON
(Continued)
IF ICE BEGINS TO FORM NEAR THE PITOT PORT (FORWARD
END) OF THE PITOT/ STATIC TUBE
IF PILOT PFD AND STANDBY AIRSPEED AGREE (COPILOT
PFD DIFFERS)
3. Pilot and Copilot Altitude . . . . . . . . . . . . . . . . . . . . . . COMPARE
IF ALTITUDES AGREE
a. Airspeed . . . . . . . . . . . . . . . . . . . . . . . 120 KIAS MINIMUM
(on slowest indicator)
b. Monitor all three airspeed indicators during changes in
power setting or altitude to determine which indicators are
inaccurate. Indications of inaccurate airspeed include:
(1) No change in indicated airspeed when power changed
and altitude maintained.
(2) Indicated airspeed increases when climbing or
decreases when descending.
c. Use SENSOR REVERSION to select most accurate ADC
on the affected PFD.
d. Airspeed . . . . . . . . . . . . . . . . RESUME NORMAL SPEEDS
IF ALTITUDES DO NOT AGREE AND AMBER ALT MISCOMP
MESSAGE COMES ON
a. Altimeter Settings . . . . . . . . . . . . . . . . . . . . . . . . . . VERIFY
(both pilot and copilot have the correct altimeter setting)
IF ANNUNCIATION DOES NOT CLEAR
b. Pilot and Copilot Altitude. . . . . . . . . . . . . . . . . . COMPARE
(with standby altimeter)
The standby altimeter uses the same static sources
as the pilot’s side air data computer (ADC1). Do not
use standby altimeter as sole source in determining
correct altitude.
