How about this one?
In the climb an aircraft has a thrust to weight ratio of 1:4 and a lift to drag ratio of 12:1. While ignoring the slight difference between lift and weight in a climb, the climb gradient will be?
a 3.0%
b 8.3%
c 16.7%
d 3.3%
Could someone please work through this question for me, the answer given is c 16.7% . I am trying to work through it, but my mind has gone blank for the moment.
Cheers
