The EFD1000 ADAHRS is normally stable, self-correcting, and accurate. The pilot may
elect to manually reset it if pitch and roll indications disagree with the standby attitude
indicator, or the ADAHRS is suspected to be inaccurate (e.g., following aerobatic
maneuvers). The ADAHRS reset function is analogous to “caging” a gyroscopic attitude
indicator.
NOTE
When an EFD1000 ADAHRS is manually reset in ight, it performs an abbreviated
initialization that usually takes less than 30 seconds.
During the initialization, the attitude and direction information are removed and replaced
with red “X”s and the annunciations, “ATTITUDE FAIL” and “DIRECTION INDICATOR FAIL” are
presented.
Gentle maneuvering during the initialization is permitted.
The ADAHRS reset is considered complete when the EFD1000 attitude and heading are
once again displayed and the attitude display is stable and correct with respect to other
sources of attitude information.
