First of all, the issue of ELTs and crashworthiness and the capture of the emitting signal has been the subject of seven TSB recommendations following the crash of an air medical helicopter out of Moosonee, Ontario, that occurred back in 2013. Those seven recommendations—some of which are addressed to Transport Canada and some addressed to the other government regulators and the industry—touch on things like crashworthiness, the first burst response so that the signal gets captured by the satellite and so on. We can provide more information if the committee would like.
These seven recommendations are currently ongoing with Transport Canada. The other technology that you referenced is a technology that is called a SPOT tracker. There are various models. That can provide a signal to people on the ground who are following that aircraft, but it hasn't necessarily met the crashworthiness standards of an ELT. It would be up to Transport Canada to work with other regulators to determine if it could meet the requirements in lieu of an ELT. For now, we've made recommendations specific to improving the robustness, the crashworthiness, and the ability to signal the ELTs.
