Hi,

 

I did some night flying with several liveries and noticed that when i am at the gate, logo lights are switched on and showing in the external model, but when i start the pushback they no longer are illuminated while the button is still in on. This is during pushback and engine start then they illuminate again.

 

Is this the same in real life or is it a bug?? 

 

never noticed this in real life.

 

RGS,

This behavior is discussed in the introduction manual. It's under "777 didn't so what I expected" or something like that.

The electrical synopsis page will give you a clue as to what was going on.

"Load shed"

There's not enough electricity available (being generated by the engine generators, apu and Batteries) to supply all the essentials and non-essentials, so some systems will be "shed" ie "turned off" till more power is available.

 

Logo lights is a "non essential", whereas things like IRS Navigation, Fuel pumps, the engine starter etc is "essential".

Some big named companies don't even use logo lights.
