I get the U.S. "
Flying" magazine, plus the U.S. AOPA magazine.
"Flying" is a good interesting and educational read for an instrument pilot; this subject is not adequately addressed by any UK magazine, presumably because the market is too small.
This subject has been done to death here and elsewhere a number of times. My own suspicion is that the UK mags are read by a lot of people who don't fly (i.e. plane spotters, and ex PPLs) - it's the only way I can explain a lot of the content. They are also very "British", in the anti aspirational sense; I am sure that if they wrote a piece on some new £300k plane they would get a full bag of complaints from readers who can't afford one of those.
