ATPL Perf and Load Question

[Hailstop3]

Hi

I'm in the process of self studying my Australian ATPLs and have my performance and loading exam on the 13th. I think ive got a grip on it all except for one thing that is really bugging me. My current study notes don't seem to cover turboprop aircraft too well which is half the problem.

Here are 2 questions.

A turboprop aircraft's max L/D speed (best lift drag ratio speed) is at Y. At what speed do you need to fly to achieve max rate of climb?

A turbojet aircraft's max L/D speed is at Y. At what speed do you need to fly to achieve max angle of climb?

Both questions have the options Y, less than Y, greater than Y.

My problem is that the correct answer for both is Y.

I understand that obviously there is a difference in relation to best angle and rate of climb from the power required/power available curves, and drag curves, that is due to their propulsion methods, but could someone please explain it all relating to the 2 aircraft as i can't seem to nut it out.

Thanks in advance.
