Indirect indication

• A. A direct readout from the attitude indicator.
• B. A reflection of aircraft pitch-and-bank attitude by instruments other than the attitude indicator.
• C. An indication of climb rate.
• D. An altitude readout from the altimeter.

Answer: (B)

Indirect indication means you determine the aircraft’s pitch and bank from instruments other than the attitude indicator. The turn coordinator, with its canted gyroscope, shows roll information indirectly through the miniature airplane’s tilt and the rate of turn, so you can infer bank angle even if you’re not looking at the attitude indicator. In contrast, a direct readout from the attitude indicator shows pitch and bank directly, the climb rate indication relates to vertical speed, and the altimeter provides altitude. So the best choice is the instrument setup that reflects attitude indirectly through others.
