Agreed, there's bound to be a handful of aircraft in Europe capable of flying, probably those too damaged in say late 97 early 98 to transfer to the middle east but repaired later from scrounged/cannibalised parts. My guess is something like 3-4 fixed wing fighter types per army Corps would be a decent figure with a serious lack of fuel and perhaps ordnance.

"Shutterbug", from Twilight Encounters has two Soviet planes listed as attached to one of their Army HQ's, both set up for recce missions from memory but only used for absolutely VITAL tasks.

There would probably be a similar number of cargo planes, and a couple of helicopters available to each Division (as per US 8th ID in the Eastern European Sourcebook) but again fuel, ammunition and parts will keep them on the ground more often than not.

A few civilian light aircraft would probably have been pressed into service to be used as spotter craft and the occasional flight by somebody VERY important (Corps commanders going to a meeting prior to the Spring offensive for example). Microlights and ultralights would see some use perhaps as artillery spotters, but they'd be universally hated by the pilots for their slow speed and extreme vulnerability. Being assigned as a pilot may even be considered a punishment in some cases.
