Question 1

A tachometer reads 2,400 RPM. If RPM decreases by 15%, what is the new reading?

Accepted Answer

2,040 RPM

Answer

Fifteen percent of 2,400 is 360, so 2,400 minus 360 equals 2,040 RPM.

Question 2

Two aircraft are separated by 5 nautical miles on radar. The minimum required separation is 3 nautical miles. How much buffer separation exists?

Accepted Answer

2 nautical miles

Answer

The buffer is the actual separation minus the required minimum: 5 − 3 = 2 nautical miles.

Question 3

A temperature gauge reads -20°C outside. The cabin temperature is +22°C. What is the difference between outside and cabin temperature?

Accepted Answer

42°C

Answer

The difference between +22°C and -20°C is 42°C (subtract a negative equals addition).

Question 4

A radar scope shows an aircraft at bearing 090 and range 20 miles. A second aircraft is at bearing 270 and range 20 miles. How far apart are the two aircraft?

Accepted Answer

40 miles

Answer

The two aircraft are on directly opposite bearings from the radar, so their total separation is 20 + 20 = 40 miles.

Question 5

An aircraft transponder code is set to 7600. What does this squawk code indicate?

Accepted Answer

Radio failure

Answer

Squawk 7600 is the universal code for loss of communication (radio failure) on an aircraft.
