What is the difference between the ADI turn information and the conventional Attitude indicator?
A – The bank angle display is driven in a manner similar to that used in the pictorial turn and bank. The only difference is that in this instrument the display shows bank angle instead of turn rate. The advantage of this is that the presentation is instantaneous data only. It cannot drift to accumulate error as is possible with the more complex AHRS driven systems. It shows bank angles of up to +/- 45° while the requirement on conventional gyro horizons is +/- 100°. To compensate for this, flashing red arrows point in the direction the stick is to be moved to level the aircraft when the bank exceeds +/- 30°. Note that when flying on instruments the object is to stay level or at least in shallow banks. This instrument is therefore designed to keep the pilot out of trouble.
