Is there another airbase where Y20 are regularly seen? PErhaps a training base? Where *is* pilot/crew trainign for Y20 done anyway?
Or is it done right there at Yanliang?
Most of the training is probably conducted in the classroom as well as the simulator. When I did my Q400 type rating conversion course, the FlightSafety facility in Farnborough also housed a C-17 simulator where I'd constantly see RAF crew going in and out from the cafeteria into the sim hall. No.99 Squadron is the only unit in the RAF that operates C-17s, and the unit itself only has eight airframes - that's why I'm almost certain most of their crew training is conducted in the sims. If we were to draw parallels, I could imagine Y-20 crews being trained in a similar fashion.
A pilot doesn't have to fly the real thing in order to get the stick-and-rudder proficiency in general handling, instrument flying, and non-normal procedures.... I doubt the military/government would want to risk actual airframes to allow pilots to practice emergencies anyway. That's not to say pilots won't fly training sorties, but that these sorties are purely used to teach/practice mission-oriented skills such as airdrop, low level flying, NVG operations, aerial refuelling, assault landing, short field landing... etc rather than on aircraft general handling or instrument flying. It provides the most training cost effectiveness balancing airframe mission availability as well as the defense cheque book - that's how the USAF and RAF do it anyway with their C-17s and C-130s.
Based on my understanding of the PLAAF pilot training system, conversion training (regardless if a pilot is assigned fast-jets, transport, and rotary) is completed with the actual brigade or regiment they are assigned to rather than the flying academy - The PLAAF doesn't operate conversion units similar to the USAF's Formal Training Unit or the USN's Replacement Air Group. Alas given XAC's current pace of production, I believe the priority should be placed on replacing the Il-76s (especially the refurbished ones) in the 38th and 39th Regiment from the 13th Transport Division over setting up a Y-20 training unit.
