Thought I'd add to the low voltage starts, we had one and the screen dropped off for a second so you lost visual on the instruments and we got an overtemp warning, had a look and no damage at all. but I wouldn't play with a low voltage situation, extra batteries are usually near, especially 2 yr old concorde ones..Also if the ship has sat for a bit, do a 1 or 2 minute purge, we found it helps the start.
