Arriving with 0 pax aboard and 19 jackets no refuel needed
I think a 10 minute wheels on to wheels off would be a reasonable planning number for a 92 and 15 for a 225 if bags are carried.
10 minutes for both with no bags. In a crisis situation I don't think bags are necessary.
Anything less would be overoptimistic for planning.
Just my 2 cents worth.
I don't think we will be cleared for landing on any burning rigs.
