Answer 1

Don't get in the airplane without that POH. It'll have that answer an more that you'll need to fly. You won't have YA up there you know.

Answer 2

It will fly for a little longer than the POH says it will. BUT the last few minutes will be allot quieter than normal. Sorry for the rude answer, but You said its your aircraft, so read the book.

Answer 3

Please look it up in the Pilot's Operating Handbook.  The tables are in the back.
