Intruder, I think the question is more: "if nothing else arranged/agreed"...
Actually, the more I think of it... maybe my previous was wrong.
The object of the exercise is to get away ontime (well +- depending on where you are), with the usual saftey caveats. An F/O F/E L/M F/M can get a lot done whilst the Capt is paying for this that or the other. (PS in our outfit it is usually the L/M that does the paying...)
Interested to hear from others. And let me say right now, if someone feels the urge to hijack this thread just because 411A has given his opinion, be ready to not post on the forum for a while. I won't put up with that !!!! here.
