Gomer Pylot:
Nicely summed up a lot of things.
Bu there is something missing between the FAR Part 27 certification and the operations rules / practices from what I've seen.
Part 27 (and 29) require that the takeoff profiles and distances and airspeeds recommended for same keep the helicopter free of the HV diagram. The bottom of the HV diagram for civil helicopters requires that the power used is takeoff power (which may be all you have at the conditions used for the HV curve of minimum 7,000' DA and maximum weight to hover OGE). Yet we don't use that sort of power normally in our day to day work.
If we're worried about takeoff distance or getting some air between sphincter and ground, then climbing out at the airspeeds recommended may take too much distance. It would be safer for an engine failure than climbing out sooner, but that may not be much use to you when faced with an obstacle.
Sorry to ramble on like this, but we do need some more guidance on the best way to do things.
