Our fixed wing brethren do not need type ratings in the same way as us rotary chaps - therefore, you would not have got as comprehensive an answer on Private Flting as here.
Whilst the Rotorheads strapline states "Professional", this is taken very, very loosely and all are welcome. The "rules" for rotary pilots are different in enough respects that all aspects of rotary flying are more likely to get a better repsonse here.
