but the CAA notice includes:-
"In accordance with 22(1) of Air Navigation Order 2009 as amended the following action required by this Mandatory Permit Directive (MPD) is mandatory for applicable aircraft registered in the United Kingdom operating on a UK CAA Permit to Fly"
Looks like the CAA are muscling in..............
They do just cover Civi, but ex Military are on a permit such as Hunters, Gnats and Jet Provosts, hence the Emergency AD to cover those, but as it does not state seat models, simply all seats it does make you wonder if this will be a two way thing, and something will have happened for them to issue it in the first place.
