Topic: How to recover electricity
I wanted to test eletrical system of the model and turn off generators in the air. RAT came out and ND with MCDU swithed off themselves, I turned on generators back, but ND and MCDU not return. On ECAM EL/AC page I saw sign "Emer gen", but when I tried to activate (or disactivate) it on overhead nothing happens. How to swith on ND and MCDU in this cases?
