BEFORE TAXI
These procedures should be conducted after completing the airplane’s AFM BEFORE TAXI
checklist items before brake release.
1. Standby Attitude Indicator ..................................................................................................... CHECK
a. PULL TO CAGE Knob ............................................................... PULL KNOB TO ERECT GYRO
b. Instrument Fail Flag ................................................. NOT DISPLAYED IN INSTRUMENT FACE
c. PFD1, PFD2, and Standby Attitude Indicator .......................... COMPARE and CROSS CHECK
2. Altimeters ................................................................................................. SET and CROSS CHECK
PFD 1, PFD 2, Standby Altimeter
If barometric pressure settings on the PFD1 and PFD2 altimeters differ by more than 0.03 in-Hg
(1 HPa), the baro display on both PFDs will be amber.
3. Radar Altimeter ......................................................................................................................... TEST
a. RA TEST Softkey .............................................................................................................. PRESS
(MFD AUX – SYSTEM STATUS Page)
b. RA TEST Annunciation ......................................................... ILLUMINATED on PFD1 and PFD2
c. RA Display Window .................................................... 50 feet radar altitude on PFD1 and PFD2
d. RA Ground Reference ...................................................... Correlates to 50 feet radar altitude on
PFD 1 and PFD 2 Altimeter displays
e. RA TEST Softkey ................................................................................... PRESS TO STOP TEST
f. PFD1 and PFD2 Radar Altimeter Displays ......................................................................... 0 Feet
g. RA Ground Reference ........................................................ Correlates to 0 feet radar altitude on
PFD 1 and PFD 2 Altimeter displays
h. RA TEST Annunciation ........................................................... REMOVED from PFD1 and PFD2
TAXI
The following procedure should be accomplished while the aircraft is taxiing and prior to
conducting the airplane’s AFM BEFORE TAKEOFF (RUNUP) checklist.
NOTE
Taxiing the aircraft before a valid GPS position has been acquired can cause attitude and/or
heading display to indicate a failed condition. Interference from GPS repeaters or magnetic
anomalies can cause an intermittent loss of attitude and heading displays while the aircraft in on
the ground.
1. Flight Instruments .................................................................................................................. CHECK
a. Compare attitude displayed by PFD1, PFD2, and Standby Attitude Indicator.
b. Verify the correct barometric pressure is set in the PFD1, PFD2, and Standby Altimeters.
c. Compare altitude displayed by PFD1, PFD2, and Standby Altimeter. Cross-check and verify
the altitudes agree within 75 feet.
d. Compare heading displayed by PFD1, PFD2, and Magnetic Compass.
