If you guys are trying to figure out how to get more capacity on board in order to deal with the extra drain caused by the pre-heat for kero start...

I had a discussion with Bob Wilcox a while ago about using a BMT-like approach of being able to use an auxilliary external power pack hooked up to the GSU during start-up or cool-down, so that your onboard pack did not get used up as quickly. IIRC, he indicated that while Jetcat wasn't currently providing a pre-configured approach for this, he believed it was OK for a user to manual hook up an extra pack during the start. If that appeals, you should double check with him first to make sure that I understood him correctly.

Dunno if that helps or not.
