Air Pilot's Manual. Difference in editions

[controlz]

I am hoping to understand if there is much of a difference between Air Pilot's Manual editions, as they appear to update them every 1-2 years or so. I prefer to purchase used books, however, I don't want to risk my knowledge being out of date if there are substantial differences in the last few years. Many thanks

Its not easy to tell what changes. I would say try and buy the latest due to changes in EASA and GPS use in the past few years. I dont think they've released a UK-FCL version yet.

The UK AIP can be found on the Nats website. It also lists recent changes.https://www.aurora.nats.co.uk/htmlAIP/Publications/2022-02-24-AIRAC/html/index-en-GB.html

The laws of physics (aerodynamics) don't change for the most part. But human-made laws, such as those in Air Law, change on a regular basis.
