single category for Saudi MD-90's and 717's????

Maybe with cockpit overhauls on more than one fleet. Lots of differences for the FAA to buy off on it I think.......The current setups would definitely require training every 90 days.....

I think not. The overhead panels are completely different, the DFGC's are completely different, the pedestal set up is completely different.
