What would that achieve, Beagle?
Let's say the CAA says bluetooth is illegal for airborne use.
Am I going to chuck out my bluetooth GPS receiver, which sends NMEA data to my tablet computer, and replace it with a clumsy cable connected unit? Obviously not.
Come to think of it, my tablet computer is probably illegal too. It contains a wifi radio, which isn't enabled but it could be, couldn't it? It also has a bluetooth radio. And an inductive touch screen which necessarily radiates otherwise it could not find the pen.
What about my satellite phone? It is not CAA approved. Is there any satphone that is CAA approved? I don't think so. Is the MLX770 Iridium radio sold by Avidyne CAA approved?
The whole radio approval business is still stuck in post-WW2 days which is why nobody takes much notice of it. Like it is illegal to record aviation radio exchanges - how ludicrous.
