5 Locks and 2 Pins seems to be the call I remember on the DC-3
Don't forget the pitot tube covers. And no, turning on the pitot heat will not burn the blasted things off, as a crew I know tried. Idiots..........
We had to replace the pitot tubes, I should have taken the cost out of their salary. Not for forgetting to remove the covers, but because they continued the takeoff.
