PA's in the sim are the last priority - it is getting that NITS
right to the hosties in a timely accurate and succinct fashion.
Sim technique is all about yer SOP and emergency procedure
knowledge. As an ex-checkie your emerg PA did look fine to
me (IMHO maybe just a tad too much verbality). If "PA" is a
box on the check form and he says you could've been done it
a bit better, then ask the bugger what exactly does he want
to hear (you might get him again on the next sim sesh). And
don't forget each check airman will have his own ideas about
things especially if the book doesn't have anything etched in
stone.
