I have a quick gander at the TCAS when just about to line up
GG and work out if he's going to squeeze me in after the first
landing. Usually looks good and anticipate rolling within one
minute. But you get these new ATC guys who don't know the
crews and you end up sitting there for minutes with cramped
tendons coming on. In that situation one can't argue for a TO
clearance and the Duty SATCO might be off having a nice pee
somewhere at the time.
BTW I NEVER park the brake on a runway EVER - not after an
event I was in yonks ago in the 737-400 when I lined up and
held for an intersection and the bloody thing stuck no matter
what trick I used. We had to be unceremoniously dragged off
the runway like a loathsome whore at a nuns' fashion parade.
