We are on the fax list for when TDA/TRAs are set up. (I'm amazed this service isn't available by email.)
The most active areas for these suddenly appearing are northern England and Scotland.
It is not unusual to have 3 of these promulgated in a day. This fact alone made me inquisitive.....and as the notification contains no details of what the "emergency" is I've been investigating a few.
Most of them relate to SAR ops - and I'm not at all certain that a TDA set up in this fashion will achieve the aims of the unit making the request.
As for Wales this weekend, the party flying was led by a band of very experienced instructors who were all aware of the TDA. And the SAR unit were aware of the mountain flying because the instructors made contact as part of their planning.
So stop stirring up a non-existent problem! If you weren't aware of the mountain flyers, how come you flew low over their hotel landing site ???!!!!!!
