> Another one is multiplex radio, again, it's 2025, the technology is there. Why are we still seeing so many blocked communications during emergencies in busy airspaces?

The difference between the radio on the WW2 era ex-pilot boat I spent time on recently and the radio in a brand new jet liner is crazy. The Global Maritime Distress Safety System - a global requirement from the 1980s - mandates a digital VHF radio service named DSC - it's not very clever by today's standards and it's hardly the easiest to drive UI - but it's night and day compared to what is provided for aeroplanes. First of all, and most crucial for its core purpose, many crucial elements of a "Mayday" call are automated so that rescuers have the most important information right away even if you're panicked and incoherent, and it won't get "blocked" by low priority callers trying to figure out which gate they're scheduled for, or whether they can get the longer runway for this approach.

It's almost aggressively bad, I guess they couldn't get an OK to use Morse code?

Radio navigation aids identify themselves by trnsmitting their name in morse code!

Oh. My. God.

> The only positive method of identifying a VOR is by its Morse Code identification or by the recorded automatic voice identification which is always indicated by use of the word “VOR” following the range's name.

There's such a long way from "Move fast and break things" to "Eh, it was good enough for my grandfather" and it feels as though aeronautics is very close to the latter. This would be OK if the demands on the system were declining or even steady, but they're increasing.

Demand for radio navaids is probably not increasing with the prevalence of GPS.

That said, misidentifying a navaid is particularly dangerous so they have to broadcast somethting that's clear even under adverse radio conditions.
