flight instrumentsFAA-published sample question (IRH, Aug 2021)
Your heading indicator has failed. To turn left from a heading of 090° to a heading of 360°, using a standard-rate turn, how many seconds will it take?
A
30 seconds.✓ Correct Answer
B
40 seconds.
C
50 seconds.
Explanation
A left turn from 090 to 360 degrees is a 90-degree turn. At standard rate, 3 degrees per second, it takes 90 / 3 = 30 seconds, which is how timed turns are flown with a failed heading indicator.
