Question 1

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

Accepted Answer

15 lbs/sq ft

Answer

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

Question 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?

Accepted Answer

10 knots

Answer

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

Question 3

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

Accepted Answer

6 hours 40 min

Answer

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

Question 4

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

Accepted Answer

15 minutes

Answer

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

Question 5

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

Accepted Answer

212,500 in-lbs

Answer

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