Strange zone transit
Flew to IOW today with Mrs MM,lovely day,great flights.good food etc.
Out bound,Brize waved me through,requesting me to fly 3000' on their QFE-no problem
On return leg ( an exact reciprocal of the outbound one).requested a zone transit through Brize's Class D CTA.Reply was 'transit approved but remain clear of CAS'. Eh? They were really busy so instead of requesting clarification (and making a tit of myself), I climbed above their 3500' limit.
Did they mean keep clear of their ATZ or maybe the Class A at FL55 above?
What do you think?
