PAN and MAYDAY
I got that definition from my Oxford ATPL notes. Those bas*ards have duped, conned and violated me with thier verbose and decietful ramblings.
Although, I believe the definition i put forward is down to semantics. I would not expect a student to reel me off the cap 413 definition. Although, I might pose that to them for a laugh to fill the foggy, groundschool days.
