Tips for your next sim session if you get some time to spare, keep both start levers on idle.
Single channel one Eng ils approach on one generator. As the FDs dissappear at 50ft monitor what happens without disengaging the autopilot. (hint: manual thrust)
Single Engine approach with both startlevers on idle. Engage the second AP as normally and observe. Same hint as with previous exercise.
Doing these will connect some of the dots. Even without a three axis autopilot the aircraft shows that the guys in Seattle did a very good job. None of these are legal to use in real life of course.
