Will it even get airborne? Artie suggested it works in the 737 sim. In any case your field- or obstacle limit performance must be heavily compromised?
I don't know how to quantify the extra drag but I have the feeling with an open reverser door it will be a lot. Perhaps tdracer knows if any such calculations have been made considering FAR25.933 mentioned below.
Aircraft unable or unsafe to fly, as a reason for the subsequent run-off and court hearing?
Considering the remoteness how many would even be able to distinguish an open TR door with a normal engine failure as the swing occurs close to or past V1. To make an informed split second decision.
