B206 Longranger differences training
I am confused by the concept of differences training for the B206L, someone who has a B206 rating already has B206L variant on licence.
Q: is there a laid down requirement anywhere of what ground and flight training has/needs to be done for someone to move onto longranger ?
if so who can teach it and what are the legal minimums and where is it written down?
I am talking about what is essential not talking about what is desirable.
any help gratefully recieved
