Default Re: Door warning passing through 80 knots

Do you:

Reject the takeoff?
Continue the takeoff and return to land?
Continue to your destination?
Other?
I would absolutely continue the takeoff. In this case, and because the door warning system is MEL'ed anyways, has a history of "false alarms," and the doors appear secure, I would consider it legal and safe to continue to my destination and would do so.

If the system weren't MEL'ed, I would still continue the takeoff but whether I continued to my destination or not would first depend on what happened once airborne. If it's actually open, return for landing. Just a warning, it would depend on what the checklist says. Some checklists might say land as soon as practical, some might say keep the door area clear and continue. If there was no guidance for it or it wasn't contrary to the checklist, and I was sure the door was secure (I closed it myself, no noise, looks okay visually), I'd probably continue on to my destination.

Most airplanes can fly with open doors. All airplanes can fly with false door warnings. Aborts aren't something to take lightly, especially above 80 knots on a wet runway. There are only a very few things that I would want to abort for between 80 knots and V1 (or Vr I guess, in your case). In most airplanes I've flown, a door warning is not one of them.
