Some points to consider with reference to Australian document CAO 95.7
1. There has always been different views on the actual meaning of
"locking" the cyclic and collective controls. What does the "locking" mean when talking about which devices do what and what
was the original intention by the author?
2. Also the term
"essential" when in the context of "essential to the safety of the helicopter or of the persons.
Some CASA FOI's deem refueling by the pilot with the rotors running not to be essential. As is to say it is an operational convience to
not shutdown and not an essential requirement when put in context.
3. The definition of
"immediate vicinity" when read in the context. What dimensions does this include?
Ask 10 CASA FOI's (if you can find them) the questions & you'll get 10 different opinions!
And then you'll walk away more confused!
