'Thronomister' Pressure Equaliser Requirement.....
Well
Griffo, I'm mentioning it but only because I've heard so many different versions of it that I wouldn't have a bloody clue!!
And I find it hard to believe that this thread has progressed so far on what is really a simple procedure.
Which consists of following the instructions that which every single Instructor, Check and Training or Chief Pilot I have ever flown under/for has given me. This has mainly consisted of
"Read the Flight Manual" and do what it tells you to do!
