We had about 10-12 and it was 4 to make 2 for missions. My guess is you would need at least 3 to 4 for a VOD det. That is me just guessing. No way to force fold to a point. You can bypass the broken switch, etc but if something is broken, game over. Often those guys couldn't even start. If the computer thinks something is going wrong, it will prevent the start up. You have to CTRL-ALT-DEL and hope it clears.
The other issue is the engine exhaust. It tears up the nonskid. You almost need imbedded JBD's on some of the spots. We started tracking deck temps right to watch for trends with non skid peeling up and being a fod hazard with hurricane force winds from the 22's. We had problems with the left nacelle melting life boats, chaff launchers or anything else in or around the cat walk. Those were quick lessons learned for us on how we spotted the deck for VSTOL.
