Ah.. we have the EASy...
Everything the plane does electrically is without our knowledge!
No powering up converters etc...
Just switch 2 BATT on, Power up the APU, Switch on 2 GEN and forget about it till the plane tells you otherwise...
Makes for very "easy" operation but doubts on what she is doing remain from time to time.
Got answers on PM to Questions 1,2,3 and 5
Waiting for 4...
