Where is this in LASORS? Are you implying that it is, in fact, a rating?
I was only pointing out how the CAA classify Examiner Authorisations in LASORS. It could be they do that for convenience rather than accuracy!
My reference was to the LASORS 2007 nine-page Index by Subject, where IRE(A)/IRE(H) (as well as CRE(A) and SFE(A)/SFE(H)) are listed under the heading of 'Ratings'.
Also, on the outside back cover, in describing the information it contains on the licensing requirements which need to be fulfilled to obtain and maintain each flight crew licence or rating, it lists 'Examiner Authorisations' under the heading of 'Ratings'.
But don't shoot the messenger!
