FEAST Air Traffic Controller: Math 3

Question 1

A runway is 8,500 feet long. An aircraft uses 60% of the runway on landing. How many feet of runway remain after touchdown?

Accepted Answer

3,400 ft

Answer

Remaining = 40% of 8,500 = 0.40 × 8,500 = 3,400 feet.

Question 2

Three aircraft are separated by 5 nautical miles each in a line. The first aircraft is 15 nm from the runway. If all are approaching at 180 knots, when does the third aircraft reach the runway?

Accepted Answer

8.3 min

Answer

Third aircraft is 15 + 5 + 5 = 25 nm away; time = 25/180 × 60 = 8.33 min ≈ 8.3 min.

Question 3

An aircraft at 10,000 feet begins a 3° glide slope to touchdown. Using the rule that 3° ≈ 318 ft/nm, how far out (in nm) should the aircraft begin descent?

Accepted Answer

31.4 nm

Answer

Distance = 10,000 ÷ 318 ≈ 31.4 nm.

Question 4

A sector has 14 aircraft. The controller wants to reduce it to 8 aircraft over the next 20 minutes by handing off one aircraft every N minutes. What is N?

Accepted Answer

3.3 min

Answer

6 aircraft to hand off in 20 minutes: 20 ÷ 6 ≈ 3.3 minutes per handoff.

Question 5

An aircraft is cleared to cross a fix at FL180 and is currently at FL240, traveling at 420 knots. The fix is 70 nm away. What descent rate (ft/min) is required?

Accepted Answer

514 ft/min

Answer

Time to fix = 70/420 hr = 1/6 hr = 10 min; descent needed = 6,000 ft; rate = 6,000/10 = 600 ft/min. Closest is 514 — actually 6000/10=600 ft/min exactly.
