So it the LCF has no APU,does it use an Airstart for every departure ?
Ground cart... Turns out we had some pretty lousy ground carts at Boeing Field - we got several complaints during the flight testing that autostart didn't work - turned out the ground carts were so weak that N2 spooled up so slow it was tripping the 'sheared starter shaft' autostart logic
They got rid of the APU because no one was comfortable with running a fuel line through the hinges (the flight controls were bad enough).
