My perception is that General aviation is mostly stuck in 1950ies when it comes to technology and we might be seeing an issue where the real issue is the limit of verbal communication to be unambiguous enough for modern standards.
It would be fairly easy to replace the whole hear/repeat with an system of unambiguous text messages using hardware not much more expansive the cost of an tank full of avgas for the average plane but it seems like people still try to solve this by regulating the already crowded radio frequencies with more verbose instructions.
- wkat4242 3y agoThere is highly standardized phraseology though, through lessons learned from the terrible Avianca disaster and others. It's absolutely nothing like the 1950s. ATC controllers didn't even have visibility of most aircraft movement back then. They relied on pilots self-reporting and the phraseology was unclear. Many lives were lost due to this. The tech is still AM radio but this I believe is mainly selected due to its reliability in poorer radio conditions.
- pi-e-sigma 3y agoAM is worse than FM in every imaginable way but one - in AM you can hear if two people transmit at the same time. In the FM the stronger signal completely suppresses the weak one which can be dangerous because a pilot or the ATC could miss some radio traffic and not be even aware of it.
