Again, what am I thinking? How could I possibly question such an experienced God of the air who flys pleasure trips for a living?
I must have a word with myself and point out to the rest of the helicopter world, mil and civ that the Robinson way is the way to do it!
I had the R22 on my licence (ATPLH) in 1992 and re-taught a private owner with 120 hours how to fly because he was scared of the aircraft and what would happen if the engine failed - I am quite aware of the power and performance issues with a single-engined piston helicopter thank you.
It might be safer to look at MP margins at Vy than try to come to an OGE hover if conditions don't allow it.
You are not listening - it is safer to confirm that you have take-off power available before committing to the hover rather than relying on a hand-me down approximation which seems to vary - is it 6 or 8? very scientific and professional.
