Possibilities include electrical failure, AHRS malfunction, attitude indicator failure,
heading indicator failure, turn coordinator failure, accidentally or inadvertently touching the trim switch (in some models, bumping one side of a split trim switch will disconnect the autopilot but leave a flight director engaged, making it look like the autopilot modes are still engaged).
Your
heading indicator has precessed a bit, so you're actually heading about 105 according to your compass.
The primary attitude indicator is 2149ドル and the G5
heading indicator is 2449ドル.
Concordantly with the idea of a common direction indicator (
heading indicator) synchronising group movement, (magnetic) alignment was more pronounced in groups than in solitary individuals (Hart et al.
"We really just did pretty simple failures, such as air speed, altimeter, and
heading indicator. We wanted to look at their process - how they reacted to something that didn't look right," Casner said.
ALSO KNOWN AS THE BEARING DISTANCE
HEADING INDICATOR (IBDH), AND THE SIMPLIFIED SURVEY SYSTEM (SSS).
Here's why, plus an overview of the G5
heading indicator.
The pilot did not scan the attitude gyro,
heading indicator, radar altimeter, turn needle or ball after the initial power pull and attitude setting for the instrument takeoff.
Third, the A36's
heading indicator is electric, not air-driven.
The bearing pointer was useful for navigation, but that compass card was a challenge because the numbers on it never corresponded to your actual heading on the
heading indicator unless you were really diligent at manually adjusting it.
Lacking any airdata input, however, its airspeed, altitude, vertical rate and
heading indicator are GPS derived.

heading indicator, altimeter, and vertical speed indicator;
