UK IRT and IMC Rating

If you are thinking of buying RANT because you are about to start a course to gain a UK IRT or IMC Rating, then the following publications will be useful to you (click the buttons to find the documents):

The UK CAA Standards Document 1.

This goes through the format of the initial IR test and lists the standards expected. This is the December 2025 edition.

The UK CAA Standards Document 25.

This goes through the format of the IMC/IR(R) Rating initial and revalidation tests and lists the standards expected. This is the August 2023 edition.

CPL Comments.

Nothing to do with instrument flying, but this is a compilation of points that have come up during initial CPL Skill Tests over the years written by Steve Oddy. Complying with all the points mentioned won't guarentee a 'pass' but it should make a 'fail' less likely.

Instrument Rating Comments.

These are updated compilations of points that have come up during initial IRTs over the years written by Steve Oddy which were also published in Flight Training News a few years ago. Complying with all the points mentioned won't guarentee a 'pass' but it should make a 'fail' less likely.

UK Air Operations has amendments wef 30 October 2025. However, ATOs have up to a year in which to implement the changes. The changes affect go around decisions and RVR, and so there are 2 compilations, depending on whether you are operating to the new criteria or the old ones.
