This is an update for FSX of the SGA DC-9-30.  
I found that all the base models had the 
positive and negative g-limits at the end of 
the [airplane_geometry] section of the 
aircraft.cfg file set to 0. This caused the 
aircraft to crash on loading as everything in 
the sim has at least 1 g of force on it most 
of the time.  After correcting that, I 
corrected the contact points; fixed the 
problem with the engines not running or 
shutting down when the aircraft loaded; I 
always start with them running, because of 
doing the updates. For every update, I reload 
the aircraft dozens of times.  I updated the 
flight dynamics; and added some gauges to the 
panels.
