Determine approximate value of approach angle if, overnose angle is 20° and approach speed is 100knots.(a) 13°(b) 5°(c) 2°(d) 3°The question was posed to me by my school principal while I was bunking the class.My doubt is from Crew Station in division Crew Station, Passengers, and Payload of Aircraft Design

Answer»

The correct option is (a) 13°

The explanation is: GIVEN, overnose angle O = 20°, APPROACH SPEED V = 200knots.

Now, Approach angle A is given by,

A = O – 0.07*V = 20 – 0.07*200 = 13°.
