I copied and pasted the "electric_always_available=1", it seems to have made no difference. Did two flights in the last two days and the power cut out both times shortly after take-off. Does this fix work for everybody? Only after running the APU did I have power on again. Basically I have to run the APU all the time if I want to use my GPS (which I do). Also shouldn't the fuel load change after running the APU for a length of time on the ground? Thanks. It works great for me. Are you sure you have entered the fix into the correct section of the aircraf.cfg? [electrical] electric_always_available = 1 max_battery_voltage = 24.0 generator_alternator_voltage = 30.0 max_generator_alternator_amps = 400.0 I always turn the APU off after I have started the engines. And as for the APU using fuel when being used. I believe it should, but I find that it doesn't seem to use any at all, no matter how long I use it for. Note: I can't start the engines without the APU unless I use CTRL+E. Mark

I double checked all 4 aircraft cfg files I have (2 for each 100 & 200) and yes I did put them in as you outlined. For the hec of it I double checked again and timed it just sitting on the tarmac at 11 minutes my GPS shut off. Hit the battery switch again , and the avions switch again and still no GPS.

If it matters here is what I do. I turn on the master battery switch on from the top of the flight engineer's panel, then my avionics switch on my keyboard and the GPS comes on. If I don't hit the master battery first the GPS won't come on when I hit the avionics switch. So I think that part is working like it should, it's just that I lose power to the GPS unless I run the APU the whole time.  Strange hey?

I too can't start the engines without the APU on. I appreciate you trying to help Mark.
