Yes, this is not a very technical question, but is related to the fliers. Why do some of you put on gloves while flying? Similarly why some people prefer to put gloves while driving? Any special reason for all this around ?
I've flown with some pilots that used gloves during take-off and landings as they believed it would give them some added protection in case of an onground accident with fire on the flight deck/escape routes.
Another guy explained that his hands were often sweaty and used gloves for a better grip on the "pretzel".
The hand warmers are Part 2 of the STC that provides automatic pilot self-ego control and self-gratification. A mechanical hand decends from the overhead every time a pilot gets up and pats him on the back.
