411, yeah not a good idea at all to select it off too soon. On our checklist it was about item number six or so. Gear, power, flaps, temps, fuel heat, water.
Somebody selects GFP in the air, he's sure trusting those squat switches to keep his butt in one piece, ain't he.
I'm guessing that was a Fokker machine. I've never flown that one. I believe it had a slightly different system for selecting GFP than the Fairchild.
