I use https://gb.readly.com/ and get all the magazines inc US Flying for a low monthly fee, and I can read all other stuff I am interested in as well and family on same account, great value I think.
I get the AOPA (US) rag as well as FLYING and the CPA (Cessna Pilots Association) mag. Flying will hardly ever write something negative about an airplane, but the Peter Garrison articles are worth it. It’s cheap here in the US, so I keep it. AOPA of course is a club mag and of varying quality and the CPA one is highly specific to Cessna operators (I get it because of my role in our club).
I read flying and motor mags in the Aberdeen town library as a student. I get the LAA mag as a member benefit. I skim through most of it. I’ve bought maybe as many as 6 flying mags in my lifetime, for specific adds. I’m not very interested.
But I do look at the AAIB and NTSB reports, and daily check ANN and Avweb.
And I buy a motor mag every 12 years when I’m thinking of changing my car.
I like the technical articles of kitplanes, which is available on their website. How they are still free I don’t know but it’s great !
I read just the US AOPA one which comes monthly with my US AOPA membership. For me, the content is OK for a quick thumb-through.
For some reason I receive Flight Training News – basically an FTO industry newspaper. It’s not bad for a 5 min read and after that is it very good for lighting the incinerator in the garden, or mixing up epoxy on. They dedicate a whole page to CAA license issue statistics, but they end in 2016 and they never realised that the CAA recently added later ones to their website
BTW I have a large quantity of the US AOPA mag, going back to 2013. Free to anyone who wants to collect it or pay for shipping
It’s quite a good “grass roots” type magazine; lots of taildraggers. Appeals to the broadest part of GA, supposedly.
There seems to be two extremes with niche magazines:
US
UK
France
The UK Pilot magazine has just run an article on the new aggressive CAA infringements policy, including the “interesting” conduct of certain of its officials, which goes way beyond anything that any other UK publication would dare publish. It is also spot-on in its information. I admire the magazine for that.
Poland used to have “Pilot Klub” but it shut down some years ago. They published a lot of my articles. The guy who ran it became an airline pilot, I think.
I’ve found them pretty poor for many years. I always thought the USA aopa mag was the pick of the bunch but I have to say I haven’t read it for many years.
I’ve always thought Propliner was the best of the aviation magazines and even now when I read back editions I think it’s quite a good historical account.
