Time for the FAA, or someone's CAA, to collate a series of audio recordings on the flight deck. They need to monitor the FC r/t for internal and external comms. It will take a while no technical problems.
Then do a good media launch and let pax here: "AB123 this is XYZ, descend to #!!!!!!!# and ????? heading." then "AB123, repeat please?" and so on. Pax behave stupidly = Yes. So educate them.
Good idea in theory except some PAX would probably be encouraged by that and would purposefully sit using mobile phones on board just to cause interference, thinking it's all such a big laugh. The mentality of some people is stunning.
I mean we all know lasers are bad, but it doesn't stop idiots shining them at cockpit windows. We all know you can't take sharps or liquids on planes, but you still get frequent flyers arguing with security personnel who take these things off them. We all told not to stand up and get our bags until the seat belt sign is off, but we still see people getting up on the taxi to the gate to get things, ignoring the CC demands to sit down...and then moaning when they get hurt from sudden braking.
Being unaware of regulations is one thing, but when it comes to commercial aviation too many pax are just ignorant and deliberately flout the rules.
