I beg to disagree: there are quite enough corners of the UK where you can
crash unobserved and are unlikely to be found until a farm hand comes by
on a tractor next day or next week.

One thing bothers me about the UK scene: although the dropping of 121.5
MHz by CORPAS-SARSAT is an international decision and will affect UK
users, there seems to be no publicity for it here and no 406 MHz ELT
equipment available or promised by the likes of RD Aviation.

I notice that all ELT units are very low power on 121.5. They are either
100 mW or don't bother to quote power, so I assume they are 100 mW by
default. I would not want to rely on such a low power transmitter for
non-satellite crashed detection.

Can any of our American friends say what the typical detection range is
for either 90C or 406 ELTs on 121.5?
