CM,
Thanks for that info! Very valuable.. will look up some information for own reference.
Final thing:
The route on the way back was slightly different to route via Wittering MATZ.
Leaving Nottingham we got East Mids Approach who cleared us and then released with Squawk 7000.
Day was Sunday. Time Approx: 16:20.
Contact Wittering MATZ for 'MATZ and ATZ' Penetration.. No Answer on any frequency.
Couldn't see anything in the NOTAM's and after multiple attempts.. I decided to go to London Information on 124.600 and opted to route around the MATZ/ATZ.
One can still fly though the MATZ but not the ATZ whilst making blind calls?
Correct?
It's academic anyway as we routed around the zone.. but just wondered about protocol!
