Non-transponder access to Class E+TMZ airways
Just been watching, courtesy of FR24, a number of FLARM-equipped gliders crossing/operating in N560 south of Inverness between FL150 and FL180. This is Class E+TMZ airspace. While gliders have an exemption from transponder carriage between FL100 and FL195 over much of Scotland, as I understand it that only applies in Class G airspace.
I guess these gliders may have got RT clearance to cross non-SSR - is that a normal procedure for these Class E+TMZ airways?
Complication is that although Scottish is the promulgated authority for this section of N560, I noticed that a few of the Inverness outbounds were still wearing Inverness squawks as they flew through the area where the gliders were operating. Is this airspace delegated to Inverness?
