offending system may also have a bonding issue to the airframe that needs to be
corrected.
Run engine(s) from idle to take off power and verify that the heading does not change by
more than 2º. Prop wash at higher engine RPMs may cause a heading shift; try an
alternate static source if this is an issue.
This completes all RSM calibration and heading tests.

Ground Test Procedure
The ground test procedure will consist of checking for proper operation of the following
items:
Airspeed Tape and Altitude Tape
AHRS Sensor
GPS Sensor Inputs
Navigation Sensor Inputs (if installed)
Backup Navigation Indicator
Autopilot Sensor Outputs (if installed)
Ancillary Equipment Heading Check (if using heading output from EFD or ACU)
Ancillary Equipment Air Data Check (if connected)
EMI Test
Flight Control Interference Check
OBS Test
CAUTION: Do not exceed the aircraft’s maximum Airspeed, Altitude, or Vertical Speed at anytime
during the testing. Damage could result to the pre-existing aircraft instruments.
NOTE: When changing indicated airspeed or altitude on the ground using pitot/static test
equipment, changes in the AHRS display of pitch, roll and heading will result, possibly
accompanied by a CROSS CHECK ATTITUDE annunciation. This behavior is the result of the
Kalman Filter algorithms employed in the EFD1000 attitude solution. These changes in pitch,
roll or heading are normal and do NOT indicate a system failure. The integrated nature of the
EFD1000 AHRS algorithms is such that AHRS performance can only be properly evaluated
during flight or ground maneuvers.
10.6.1
Indicated Airspeed Display
WARNING:
This test must be accomplished by an appropriately rated mechanic or repairman
(14 CFR 43.3).
Use the Installation Final Check Sheet of Appendix B to record the aircraft speed settings
from the Aircraft Flight Manual in the IAS Setting column. Set the Pitot/Static test set for
5000 ft. above field elevation. Increase airspeed to Vne and check all Speed Bands and
Speed Markers listed in table.
