Right but that's not what you said.
I've noticed that DoD light stuff doesn't show up but the heavies do, probably due to the nature of their work and the locations they fly.
If you look at the FAA requirements for ADS-B, there aren't many civil aircraft exempt...
Pretty much exactly what I said when I posted, “and won’t appear on flight radar”
No IFR flight plan - no one knows they’re flying. No one is even looking for them.
Won’t appear on any app, or FAA tracking, because they don’t have ADS-B.
Won’t appear because they fly below the actual radar (raw radar, not ADS-B) horizon for many areas. They do that as a matter of course, and they do that for tactical training reasons. FAA radar and bad guy radar work similarly. Helicopters try to stay under it.
Won‘t appear, in other words.
Heavies are required to have ADS-B to operate in Class A. They have to operate there, all the time.
They were the first to get ADS-B. Fighters and tactical airplanes next.
Helicopters last. DOD has retrofitted about 1/3 of their airplanes. Helicopters can’t get high enough to be in class A, and rarely go into class B. So why rush to get them outfitted with ADS-B?
