tecpilot & offshoreigor:
I can remember flying formation with a KA-32 in the North Sea and seeing him wave goodbye and accelerate to 190Kts+ as he left us in his dust to go back to Mother.
--------------------------------------------------------------------------------
This is impossible, the koax main rotor system on the Ka-32 doesn't allow speeds greater than 140-145kt.
---------------------------------------------------------------------------------
We were doing 150 and his departure rate on our Radar was 40 kts.
So... 50 kts of tailwind?
You are discussing about IAS and Ground Speed, aren't you?
