Hi guys,
Thanks for the responses.
Capt Solipsist - great explanation of the drag curve. Thanks for pointing out how Vs fits on to it.
What Im still trying to find though is the practical use of the drag curve. For example I have a double engine failure. I have indication on the EADI of fast/slow. What do I fly? I want to be flying at min drag for best glide performance, but how do I know what this is? With an aircraft mass that various by many tonnes it isnt practical to know a speed for each case. I am hoping someone can say that a good ballpark is to fly 'x' on the fast/slow indicator.
Any help?
Blah
