Flight Mechanics: DGCA Technical General questions
Flight mechanics balances lift, weight, thrust and drag in level flight, the climb, the glide and the turn. It adds load factor, the ratio of lift to weight, and twin handling after an engine failure.
Among the 36 questions you will meet stall speed in a turn, glide range from L/D, load factor and the minimum control speeds. Exam sessions have featured 2 of these mechanics items.
In a steady climb lift is slightly less than weight, since it balances only the part of weight at right angles to the flight path. Stall speed rises with the square root of load factor, so a 60 degree bank raises it by about 41 per cent. Weight changes the best glide speed, not the still air glide range.
