Electrical power

GaryG

Loving this aircraft in MSFS, although I have a problem when closing the throttle following cruise flight. The electrics all trip when the throttle is closed. I get a AC1, AC2, AC3 & Fuel Pressure warning whenever reduce the throttle to idle. I can reset in flight, but on landing again closing the throttle gives a power failure. I'm using FSUIPC and have the throttle axis set via FSUIPC, not the sim. Has anyone else had a similar problem?

Hi Gary, I’ve fsuipc too, but not problem with the throttle. Could it be the throttle dead zone isn’t set quite right in fsuipc?

Can you check if anything is assigned to the APU STARTER control? That assignment triggers the throttle start/relight button which in flight triggers the generator offline.

I too have the same issue, every time I pull the power lever to idle the Generator trips offline and takes the electrical system with it. If you bring the power lever back up around 5% or so and push the Generator Reset it brings it back online. I'm not using FSUIPC and do not have anything assigned to APU starter. My throttle has no switches at idle, you must go over a gate, so there doesn't appear to be anything else but throttle movement to idle causing the issue.

Edit: It appears to be tied in with the Engine Ignition switch logic. If the switch is on then the generator will always fail at the same throttle position in flight, regardless of N1 however it does not fail on ground. When the switch is off then there is no issues throughout the throttle range.

Thanks Martyn, I had allocated a button on FSUIPC to APU STARTER. Moving the power to idle was causing the power to trip inflight when the switch was in the APU ON position. Switching this off has cured the problem! I tried this several times, APU OFF keeps the electrics online, APU ON and it trips out everytime. Also probably explains why this only happened in the air - there was no problem while taxying. Thanks for the support!
