Question 1

On a three-pointer altimeter, the shortest needle points to 1, the medium needle points to 5, and the longest needle points to 3. What altitude is indicated?

Accepted Answer

1,530 feet

Answer

On a three-pointer altimeter, the shortest needle reads thousands (1,000), the medium needle reads hundreds (500), and the longest needle reads tens (30), giving a total of 1,530 feet.

Question 2

An aircraft is heading 090 degrees and makes a 90-degree left turn. What is the new heading?

Accepted Answer

000 degrees (360)

Answer

Starting at 090 degrees (east) and turning left 90 degrees subtracts 90 degrees, resulting in 000/360 degrees (north).

Question 3

During a standard rate turn, how long does it take to complete a full 360-degree turn?

Accepted Answer

2 minutes

Answer

A standard rate turn is 3 degrees per second, so 360 degrees divided by 3 degrees/second equals 120 seconds, or 2 minutes.

Question 4

In the Northern Hemisphere, a magnetic compass will do which of the following when turning toward north?

Accepted Answer

Lag behind the actual heading

Answer

Due to magnetic dip in the Northern Hemisphere, the compass lags when turning toward north, requiring the pilot to stop the turn before the compass reaches the north indication.

Question 5

If the attitude indicator shows the miniature aircraft below the horizon bar with wings level, what is the aircraft doing?

Accepted Answer

Flying in a nose-low (descending) attitude

Answer

When the miniature aircraft on the attitude indicator is below the horizon bar with wings level, the aircraft is in a nose-low, descending pitch attitude.
