It's not necessarily my opinion that you disagree with. My opinion isn't formed yet, and I'd like to see some solid (logical) arguments FOR it that counter my (gut) reaction.
To continue, I don't see the logic behind "my point is if 121.5 ELT was mandatory, then I see no use crying about the changeover being mandatory". What I see you saying is "there was a minimum level of SAR alerting required. There is now a better (for everyone, with the sole detriment being cost) option available. There is no need for choice in the matter, even though there is a poor option available, it should be mandated we accept the best option".
Is that correct? - I'm not trying to be argumentative, I'm trying to understand the thought behind the belief.
"There is a public cost to accidents that justify mandatory mitigation of your risks"
Hmmm, this statement is what I struggle with. When you draw the obvious line (following this line of reasoning to its conclusion), why do you choose to include 406Mz ELT's?
Perhaps you don't care to elaborate, and that is fine, too.
