panel didn't change too much for AMP mod. The old analog engine instruments are gone, and replaced with an additonal MFDU, the same as what the yoke yankers have. A few additional minor changes. Single battery, DC panel changed some.
The M model FE
panel has a few more changes, but not too radical. APU egt is gone, now displayed on the MFDU. Engine electronic control power switches are new, and the AC
pwr panel is different, as well as bleed air panel. MADAR is replaced with a new system that uses a MILTOPE laptop, looks somewhat like old MADAR. Fuel temp ind gone. Hyd, and fuel panels didn't change. DC panel is a bit different, the aircraft now has 2 batts, one being for the APUs.
Big changes with the circuit breaker panels. Legacy, AMP, and M models are pretty different. What was easy to find in the old days can be a challenge now.....Of course the T.O.s are at times very different.
However, get out of the cockpit, and the M model is a bit more different....
