Question

The aircraft is taken to the level ground operating for ________

(a) considering vertical component of the wind

(b) considering horizontal component of the wind

(c) considering both horizontal and vertical component of the wind

(d) neglecting the effect of wind

The question was posed to me in exam.

My doubt stems from Effect of Wind on Climb Performance and Descent Performance in section Climb and Descent Performance of Aircraft Performance

Answer 1

Right choice is (b) considering horizontal component of the wind

The explanation: The aircraft is taken to the level ground operating for considering horizontal component of the wind. Wind is the relative velocity between the air mass and the ground. Usually wind is assumed to have only a horizontal component but there exists vertical component which may affect the aircraft at considerable height.
