Hi there,
having trouble figuring out the following QDB questions, would appreciate if someone could shed some light on it:
1. Whilst maintaining straight & level flight with a lift coefficient of CL=1, what will be the new value of CL after the speed is increased by 41%:
a) 0.25
b) 0.50 (correct answer)
c) 0.60
d) 0.30
2. Airplane flying at 100 kt in straight & level flight is subject to a disturbance that suddenly increases the speed by 20 kt. Assuming AoA remains constant, load factor will initially be:
a) 1.41
b) 1.44 (correct answer)
c) 1.30
d) 1.04
3. In straight & level flight at a speed of 1.3 VS, the lift coefficient, expressed as a percentage of of its maximum CLMAX, would be:
a) 169%
b) 130%
c) 59% (correct answer)
d) 77%
Help appreciated, thanks a lot!
