FEAST Air Traffic Controller: Math 4

Question 1

An aircraft burns fuel at 220 lbs/hr. If it departs with 3,300 lbs of fuel and must land with a minimum of 660 lbs reserve, what is the maximum flight time available?

Accepted Answer

10 hr

Answer

Usable fuel = 3,300 – 660 = 2,640 lbs; time = 2,640 ÷ 220 = 12 hr — wait, 2640/220 = 12 hr.

Question 2

A controller vectors an aircraft on a 360° heading for 8 minutes at 240 knots, then turns it to 090°. How far north of the starting point is the aircraft?

Accepted Answer

32 nm

Answer

8 min at 240 kts = 8/60 × 240 = 32 nm north.

Question 3

A departure sequence has aircraft launching every 90 seconds. How many aircraft depart in 12 minutes?

Accepted Answer

9

Answer

12 min = 720 sec; 720 ÷ 90 = 8, but the first departs at 0 sec so total = 9 aircraft.

Question 4

Aircraft are required to maintain 1,000 ft vertical separation below FL290 and 2,000 ft above FL290. If one aircraft is at FL310, what is the minimum altitude a following aircraft may fly?

Accepted Answer

FL290

Answer

FL310 is above FL290, so 2,000 ft separation is required: FL310 – 20 = FL290.

Question 5

A groundspeed of 480 knots equals approximately how many nautical miles per minute?

Accepted Answer

8 nm/min

Answer

480 knots ÷ 60 = 8 nm per minute.
