Anyway doing both and should be good in US and Canada going forward after those.

Good, I have been following this whole issue very closely and was fairly certain nothing had changed. At this time there is no legislation requiring a 406MHz ELT in Canada, nor is there a schedule for any to be finalized.
I have a 121.5 ELT and a SPOT and am watching the changes in technology in the hopes that I can avoid equipping with a 406 and then having to replace it with an ADS-B-based solution that gets mandated 6 months later.

A G-switch would be very susceptible to impacts from non-life-threatening events... Hitting the canopy edge while getting in/out of the airplane could give it a 10G shock, for example. Dropping a tablet on it in flight could do the same.

A g switch that must be armed before each flight as a separate activation devise wouldn?t though. So the normal operation of a plb could be kept separate. Flip a switch and put it into g switch mode for flight use.

Agree with turbo69bird. At any rate, my original idea as stated was for the G-switch to be part of the mounting attached to the frame, not the PLB itself. With the small size of most PLBs it could be mounted within convenient reach of the pilot giving its access almost equal to being on one's person.

That’s pretty interesting Idea. Don’t know that it would qualify for the current g switch rule though unless it had a 1 lb weight on the switch. Which might make it qualify. One things for sure if there’s a way to make something qualify someone from VAF will figure it out.
Although a lot of people I talk with say the PLB already qualifys including a DPE I talked with about it.
It’s all how you interpret the rule I guess. I certainly think that for non commercial use a PLB should be an option. Or maybe just for experimentals based on this poll it seems a lot of others feel the same way!

It would be nice if the PLB manufacturers would consider a wireless activation option. I'd like to have the PLB strapped to me, but with a wireless option to allow activation by a G-switch, BRS handle, canopy eject, etc.
I haven't looked into them that much, but I'm assuming there's a window of time you can deactivate them? Say your engine quits- it would be nice to activate it, then once you've made a safe landing, deactivate it. If the landing doesn't end up being so safe, then they're already notified to look for you.
My current project is single place, so I don't legally have to have an ELT, which makes this thread even more interesting to me.
Thanks,
Rusty

Yes, there is a time to deactivate... the first 49 seconds after activation. That's all you get - after that a valid distress signal is sent as a 406MHz transmission.

I posted a followup question, but got it answered by ACK before anyone could reply. The question was- how long until the first burst goes out, and how certain is it to get to the Satellite.
Apparently the design specs for the system are that the first burst goes out in 50 sec, plus or minus 2.5 sec. If the antenna is completely intact, there is a near 100% expectation that the first burst will reach the satellite in N America. Considering all the mountains I have around here, I think I'll be installing a 406 ELT.
Thanks,
Rusty
