  1. An aircraft has a gross weight of 3,000 lbs and a wing area of 200 sq ft. What is the wing loading?

    Answer: 15 lbs/sq ft

    Wing loading = gross weight ÷ wing area = 3,000 ÷ 200 = 15 lbs/sq ft.

  2. The crosswind component equals wind speed × sin(angle off runway). If wind is 20 knots at 30° off the runway heading, what is the crosswind component?

    Answer: 10 knots

    Crosswind = 20 × sin(30°) = 20 × 0.5 = 10 knots.

  3. An aircraft has 60 gallons of usable fuel burning at 9 gph. What is the maximum endurance (no reserve)?

    Answer: 6 hours 40 min

    Endurance = fuel quantity ÷ fuel burn rate = 60 ÷ 9 = 6.67 hours = 6 hours 40 minutes.

  4. An aircraft climbs at 500 fpm. How long will it take to climb from 1,000 ft to 8,500 ft?

    Answer: 15 minutes

    Altitude to climb = 8,500 − 1,000 = 7,500 ft; time = 7,500 ÷ 500 = 15 minutes.

  5. An aircraft weighs 2,500 lbs and has a moment arm of 85 inches aft of the datum. What is the moment?

    Answer: 212,500 in-lbs

    Moment = weight × arm = 2,500 × 85 = 212,500 in-lbs.

  6. Pressure altitude is 6,000 ft where standard temperature is +3°C. The actual temperature is −6°C. What is the ISA deviation?

    Answer: -9°C

    ISA deviation = actual − standard = −6 − 3 = −9°C.

  7. An aircraft has a groundspeed of 180 knots and must travel 90 nm. What is the ETE in minutes?

    Answer: 30 minutes

    ETE = distance ÷ groundspeed = 90 ÷ 180 = 0.5 hours = 30 minutes.
