You are quite correct, mea culpa etc! Next time you are in the sim (if you haven't already tried this!) look at an ADP failure on Take Off. It gets quite exciting. The ADP fails and as it is the big mama of pumps in the C system (37 odd gpm as opposed to 5 gpm for each electric IIRC) the gear takes several days to retract. This means that you get a Gear Disagree as it over runs the time inhibit. You also get a SYS PRESS message as the pump has been signalled to operate so that inhibit is also removed. There will also be a PRESS discrete on the pump pnael. As the situation lasts over however long, you also get a latched MAINT message on the Status page.
Once the gear comes up it all goes away like magic. Gives you hours of fun if you are running the exercise, not so much fun if you are in the seat as it all happens seconds after take off.
Another good one is to fail an ADC on take off but that is for another day!"
Doors: Electric at L1 and L2, up and over, operable from inside and out. (L1 only on -200). That's the TOM fit, don't know if it is an option or not.
