Two performance questions that I have found question banks with different answer.
On a twin engined piston aircraft with variable pitch propellers, for a given mass and altitude, the minimum drag speed is 125 kt, and the holding speed is 95 its. The best rate of climb speed will be obtained for a speed of:
One question bank says 95, the other 125.
What other speeds can you derive from the above question?
The other question I found is for a piston engine maximum endurance is achieved at:
One bank says maximum rate of climb speed, the other at maximum lift to drag ratio, one and the same?
