(d) 25 unit from back wheel

I have been asked this question in an interview.

I'm obligated to ask this question of Landing Gear Arrangements topic in portion Landing Gear and Subsystems of Aircraft Design

Answer 1

Correct answer is (a) 5 unit aft from front wheel

The explanation is: Typically, for bicycle landing gear CG is aft of the midpoint between two wheels measured from front wheel.

Hence, Location of CG = distance/2 = 10/2 = 5 unit aft from front wheel.
