R66 Limitations Question
Can anyone please advice me on the limitations of the R66 Turbine helicopter on operating at high altitudes? I would like to know the dangers when operating at over 10 000 feet landing and picking up on average 3 pax.
What is the opinion of the experienced pilots on here operating a R66 at 10 000 feet plus altitudes for mountain rescues etc.
In my opinion and experience I am sure the engine has enough power but the tail rotor loosing efficiency is my concern?....please advice...
