UK - Crossing a CMATZ at the w/e.
Hi guys can somebody jog my memory, I fly a quite slow flexwing microlight no squawk and am planning at flight that on it shortest route would need to cross the Shawbury CMATZ well the Ternhill ATZ part to be exact at the w/end,
As far as I know a lot of these military airfield close w/ends and CMATZ stubs as well, but of course the ATZ would still be in force,
Now for my question, if I make a call on the controlling airfields freq and receive no reply can I cross the airfields ATZ at less than 3000ft QFE as long as I make blind radio calls.
Nick.
