Well, the fuel imbalance SHOULD take care of itself with the whole motive flow thing, but it looks like ye ole xfer/apu pump failed since you're talking about the grav feed running the APU off the right fuel system. Then again, I might be totally out of my league. Now, throw in the check valves and it does get pretty interesting.
So, for the official recap:
Mon - fuel systems, more FMS training, aircraft doors, and we actually got to go to the hangar and see a real airplane, something I haven't done in almost a month now. Had us pop all the doors, practice doing the FO walkaround, sit in the right seat and practice donning the O2 mask and generally get in the mx guys' way.
Tues - more FMS (this time it was loading approaches, VNAV advisory stuff and secondary flight plans), lighting systems, APU and powerplant. Tonight it's back over to the training center with me to run more checklists, flows, callouts and profiles with my sim partner. We've got our memory items, limitations and systems test on Tues. After that, we should know our schedules for the CPTs, oral, sim and checkride.
