The thread was moved into his forum by some moderator, no fault of the OP. It started in the techlog section which was more appropriate in my opinion.
I just wonder, do the engineering staff have access to the flight crew documentation? Something like the FCOM or OM B vol 3? That would explain most if not all of the original questions. Since I am used to them having that kind of access (its just the normal way of things in "my" company) I wrongly assumed the OP to be a flight simmer, as the questions were typical of the kind of basic stuff asked by simmers.
