The Airwolf model used for the simulation program, is actually the mock-up of the chopper used to film interior in-flight sequences for the series.
During the simulator-created shots of the two Airwolfs, a faint join can be seen down the middle of the shot, where two shots have been overlapped to create the effect of two Airwolfs.
While Hawke and Dom are "flying cold," Dom yells, "missile coming in!" There's no way to know that a missile is coming in if the systems aren't functioning and there's no way of seeing behind them.
Inaccuracy: Winchester tells Hawke that the telemetry pod has been in an F-15 at Mach 3. F-15 jets top out at Mach 2.5.
When Hawke and Dominic are in Airwolf chasing Alexei and Gloriana, Hawke's line "We'll play this one out even" stops dead, as if more dialogue followed it, but was edited out in post-production.
Unclear, but a possible blooper: When Alexei shoots Dr. Winchester, he appears to get shot on his left-hand side. Yet when we see Marella tending to his wound, it is on the right-hand side.
Hawke (unimpressed by the Airwolf simulation): I'll be outside when you're ready to fly us back to the cabin
Archangel: Hawke, Dr. Winchester has a report he'd like you to fill out
Hawke: ...I forgot my pen!
Hawke: It's Orville and Wilbur time!
This is allusion, referring to the Wright Brothers. Hawke was implying that in such a fancy chopper as Airwolf, they're having to revert to old-fashioned, unguided flight, due to having non-functioning equipment.
