The attitude indicator, sometimes referred to as the artificial horizon allows a pilot to determine a small change in the aircrafts attitude such as, a climb, descent, and roll. The attitude indicator is designed with a gyro, which is mounted inside on a horizontal plane and operates depending on the rigidity of space.
The rigidity of space refers to, “the principle that a gyroscope remains in a fixed position in the plane in which it is spinning”. The indicator has a miniature airplane in level flight that corresponds with the aircrafts change in relation to the horizon, which is adjustable up and down to align with the horizon bar, for better line of vision. The indicator also shows bank, in the increments of 10°, 20°, 30°, 45°, 60°, and 90 degrees.
Instrument check
Gyros take a small amount of time to spool up, make sure there is no abnormal sounds being made. During a turn while taxing all gyros should indicate a turn in the direction of the tune being made. Be aware that at idle power the gyros using the vacuum system may not be at operating speeds.
Another thing is that gyros take a few minutes to spin down. After shutdown of the airplane, you notice something is still running that is the gyro's spinning down.
Remember:
During a turn while taxing all gyros should indicate a turn in the direction of the tune being made.
