Question

Consider the vertical velocity of the aircraft is 10m/s and horizontal velocity is 12 m/s. Determine the value of climb gradient.

(a) 0.833

(b) 1.89

(c) 8

(d) 2.483

This question was posed to me during a job interview.

This intriguing question comes from Flight Mechanics topic in chapter Performance and Flight Mechanics of Aircraft Design

Answer 1

Correct option is (a) 0.833

The best I can explain: Climb gradient = vertical velocity/ horizontal velocity = 10/12 = 0.833.
