AoA Indicator and Accelerometer
The Angle of Attack (AoA) indicator and accelerometer displays the current angle of attack and G-
load. The left portion of the indicator shows the AoA in degrees and the right portion shows G-
loading. An index mark shows the maximum G recorded during a flight.

Attitude Direction Indicator
The Attitude Direction Indicator (ADI) shows the current angles of pitch and aircraft roll. In the lower
part of the indicator is a yaw slip indicator. Changing the rudder position eliminates slipping, so try to
have the indicator in the central position. On the front portion of the indicator are the required bank
and pitch indicators to reach the next waypoint. When both yellow bars are in the central position,
the aircraft is following the correct route. During landings, the W-shaped glidescope deviation
indicator provides Instrument Landing System (ILS) direction.
