a. Airspeed . . . . . . . . . . . . . . . . . . . . . . . 120 KIAS MINIMUM
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
decreases when descending.
c. Use SENSOR REVERSION to select most accurate ADC
on the affected PFD.
d. Airspeed . . . . . . . . . . . . . . . . RESUME NORMAL SPEEDS

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
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.
