Question

Ratio of vertical distance travelled to the horizontal distance travelled is known as __________

(a) climb gradient

(b) lift curve slope

(c) power required

(d) thrust loss

I got this question in unit test.

Asked question is from Flight Mechanics topic in section Performance and Flight Mechanics of Aircraft Design

Answer 1

Right choice is (a) climb gradient

For explanation I would say: Ratio of vertical distance travelled to the horizontal distance travelled is known as Climb gradient. Lift curve slope is change lift coefficient to the change in angle of attack. Power required is product of Thrust required and velocity of the aircraft.
