Any plane carrying the President is AF1. Doesnt matter if it's a crop duster, a vc-25a, or an SR-71. It's not always the same plane, so when the president isnt onboard they just go by normal callsigns. When the president is onboard they can fly as AF1, not squawk at all when safe to do so, fly as the planes normal callsign, or use a different call sign entirely. It really just depends on when and where the president is going and what the threat level is. So yes you can track AF1 sometimes, you can track planes that get used as AF1 most of the time as well.
