AQT Aviation Mathematics & Calculations 1 — Questions and Answers
Question 1: An aircraft travels at 180 knots for 2.5 hours. What is the total distance covered?
- 360 nm
- 450 nm (Correct answer)
- 540 nm
- 400 nm
Correct answer: 450 nm
Distance = speed × time, so 180 knots × 2.5 hours = 450 nautical miles.
Question 2: An aircraft burns fuel at 12 gallons per hour. If the flight is 3.5 hours, how much fuel is consumed?
- 36 gallons
- 42 gallons (Correct answer)
- 48 gallons
- 54 gallons
Correct answer: 42 gallons
Fuel consumed = burn rate × time, so 12 gph × 3.5 hours = 42 gallons.
Question 3: An aircraft weighs 3,200 lbs empty. With 200 lbs of fuel and a 170 lb pilot, what is the total weight?
- 3,370 lbs
- 3,470 lbs
- 3,570 lbs (Correct answer)
- 3,520 lbs
Correct answer: 3,570 lbs
Total weight = 3,200 + 200 + 170 = 3,570 lbs.
Question 4: Convert 100 knots to miles per hour. (1 knot = 1.151 mph)
- 100 mph
- 115.1 mph (Correct answer)
- 86.8 mph
- 125 mph
Correct answer: 115.1 mph
100 knots × 1.151 mph/knot = 115.1 mph.
Question 5: An aircraft is at 5,000 ft where the standard temperature is +5°C. The actual outside air temperature is +10°C. What is the ISA temperature deviation?
- -5°C
- +5°C (Correct answer)
- +10°C
- +15°C
Correct answer: +5°C
ISA deviation = actual temperature − standard temperature = 10°C − 5°C = +5°C.
Question 6: An aircraft flies at 120 knots indicated airspeed. Applying a TAS correction factor of 1.05 for altitude, what is the true airspeed?
- 114 knots
- 120 knots
- 126 knots (Correct answer)
- 130 knots
Correct answer: 126 knots
TAS = IAS × correction factor = 120 × 1.05 = 126 knots.
Question 7: An aircraft needs to travel 360 nm at a groundspeed of 150 knots. What is the estimated time en route (ETE)?
- 1 hour 30 min
- 2 hours 24 min (Correct answer)
- 2 hours
- 3 hours
Correct answer: 2 hours 24 min
ETE = distance ÷ groundspeed = 360 ÷ 150 = 2.4 hours = 2 hours 24 minutes.
An aircraft travels at 180 knots for 2.5 hours.
