Question

Which condition during taxi is an indication that an attitude is unreliable?

a) The horizon bar tilts more than 5 degrees while making taxi turns
b) The horizon bar vibrates during warmup
c) The horizon bar does not align itself with the miniature airplane after warmup.

Answer 1

Answer:The correct answer is c

Step-by-step explanation:

The horizon bar does not align itself with the miniature airplane after warmup. This indicates that the attitude indicator may not be providing accurate information about the aircraft's pitch and bank angles. A misaligned attitude indicator can be caused by various factors such as precession, gyroscopic drift, and mechanical wear and tear. It is important to ensure that the attitude indicator is functioning properly before takeoff to prevent any potential safety hazards.
