Would a scheduled domestic flight normally be allowed to operate and not transmit its location in a way that FR24 would pick up ?
Are there any other reasons as to why a daily non-military commercial 19-seat passenger flight would not show up at all on FR24 when A320/B737 overflights still show up reliably ?

However, the devices transmitting from airplane are a piece of equipment that needs to be paid. And equipment is not required yet (I think no country has introdduced ADS-B as of now as requirement).davidjohnson6 wrote:Would a scheduled domestic flight normally be allowed to operate and not transmit its location in a way that FR24 would pick up ?gloom wrote:Yes, that's still quite possible. Even with some extra functions FR24 has implemented (MLAT etc.), it's still normal thing to see a plane operated flight not showing up on FR24.

One would be not enough receivers on the ground, limiting range, others wuold include no ADS-B device on the plane, and not enough transmitters to make Mode C (MLAT) work. Also probably a couple more along the same lines.

Indeed, though Georgia, which OP asked about, doesn't have such requirements yet.

Guys, please, read carefully.
OP asked about Georgia (country), not Georgia (US state). Just next to Black Sea, on east shores. Anything "US" is not a valid answer there.
