16 / 20
An aircraft has a mass of 5700 kg, the drag at best climb speed is 6675 N and the thrust available is 15.6 kN. The gradient of climb would be:
  • A
    1.17%
  • B
    16%
  • C
    1.56%
  • D
    8.9%

Climb Gradient % = (Thrust – Drag) / Weight x 100

Use ‘g’ = 10 m/s/s. Weight = 5700 x 10 = 57000 N

Climb Gradient % = (15600 – 6675) / 57000 x 100

Climb Gradient = 16%
