Yes FerroNATS at Jerez started to be used this month. I don’t know if it is a “one of “ although if the first course goes ok it will probably be used again.
GLOBAL ATS ( GATS ) at Gloucester have been used on several occasions I think they can only do Basic, Aerodrome and Approach Radar courses.
It has been intimated that in theory you could do your basic course at Global and then join an Area course at CTC however I don’t think that has ever happened yet.
I believe this is all due to capacity issues at CTC.
