Question 1

A controller remembers six aircraft altitudes: 7,000; 9,000; 8,500; 10,000; 6,500; 11,000. How many are above 8,000 ft?

Accepted Answer

3

Answer

Altitudes above 8,000 ft: 9,000; 8,500; 10,000; 11,000 — that is 4 aircraft.

Question 2

A number string 74836 is shown. What is the product of the first digit and the last digit?

Accepted Answer

28

Answer

First digit is 7 and last digit is 6; 7 × 6 = 42.

Question 3

Two aircraft are separated by 30 nautical miles. Aircraft A is traveling at 450 knots toward Aircraft B, which is stationary. In how many minutes will they be 15 nm apart?

Accepted Answer

2 min

Answer

At 450 knots, 15 nm is covered in 15/450 × 60 = 2 minutes.

Question 4

You are given four codes to remember: 3315, 3351, 3135, 3153. Which code has the digit 5 in position 3?

Accepted Answer

3351

Answer

In 3351, the digits are 3,3,5,1 — position 3 is 5.

Question 5

An aircraft's altitude readout changes from 35,000 ft to 34,700 ft. What is the magnitude of the change?

Accepted Answer

300 ft

Answer

35,000 minus 34,700 equals 300 feet.
