August 20, 201015 yr The ground power button on the overhead has two different positions (other than "OFF") - one labeled "GND PWR ON" and another labeled "BATT ASSIST/GND PWR ON". What is the difference between the two - when would you use one over the other?

August 21, 201015 yr I only know that normally the batteries are disconnected from the bus when on GPU, and that I cannot find the BATT ASSIST term in the manual. Good question. Dan Downs KCRP

September 5, 201015 yr Oups...posted the very same question myself earlier today and missed someone else already asked the same thing...sorry!Anyway I hope someone will be able to give an explanation since it isn't in the AOM that comes with the PMDG J4100.
September 5, 201015 yr A wild guess would be that maybe the batt assist mode means the ground power is used to charge the battery/batteries if they are in a bad condition where the GND PWR-only mode is just that...meaning the battery/batteries is/are completely disconnected as long as you have the GND PWR connected...?
