am not sure. Whether it’s in their software as an available overlay, or whether it would have to be loaded up.Like you said, the mil folks have a different mission. Do those scopes overlay airways or airspace boundaries?
it would have to be FAA controllers in the aircraft, not just for the military mission, but because even standard military ATC folks who do an ATC function, are mostly tower controllers or RAPCON/RATCF controllers. There are very few ARTCC-type controllers, since the military doesn’t deal with that except for a few small areas. Plus, the FAA controllers from their respective ARTCCs already know their airspace as opposed to mil controllers having to learn it new.
For comparison purposes, Im old enough to remember seeing the PATCO strike on TV, but not old enough to know the operational details of how exactly the military ATC folks were meted out to cover the affected ATC facilities. Many were closed down, and mostly busy tower facilities and radar facilities were back filled by military ATC controllers, but I don’t know how long training and such took or what percentage of prior capability the facilities were eventually able to provide with the military controllers. @queeno or @fholbert may know the answer.
