Re: Boeing 777 door locks

Don’t confused “locked” with “properly closed”. The 777 does have main door locks that engage at 80 knots. On my 737 I have micro switches that tell me the door is properly closed but the only openings that are “locked” are the overwing exits when we have at least 50% N2 and at least three doors are...

Re: Door Latch Question

Air loads move the handle to an aerodynamically neutral position. There won’t be any indication in the cockpit if the door is otherwise properly closed. Thee won’t be unusual noise or pressurization issues. An exterior handle is not a no-go item for that operator.
