Question

A typical a/c has approach speed of 100 knots. If approach angle is 10° then, estimate value of overnose angle.

(a) 17°

(b) 25°

(c) 10°

(d) 40°

I got this question in class test.

I would like to ask this question from Crew Station in chapter Crew Station, Passengers, and Payload of Aircraft Design

Answer 1

Correct choice is (a) 17°

Explanation: Given, approach speed V=100knots, approach angle a=10°.

Now, overnose angle = a+0.07*V = 10 + 0.07*100 = 17°.
