The problem lies with different practices among NAAs when it comes to entering the ratings in licenses when getting cross-credit for a proficiency check. I have had several discussions with LT because they will not enter IR-SE in my license following revalidation of IR-ME although I have passed the IR-SE skill test prior to the IR-ME skill test. They argue that they cannot enter IR-SE into my license if I have not had an IR proficiency check in a SE airplane, but furthermore that my license is valid to fly IR-SE because of cross-credit as per Appendix 8, and their records do reflect that I have passed the IR-SE skill test.
Living outside of Norway, the problem I see is documenting to French law enforcement that I am qualified for IR-SE, since French NAA would have entered IR-SE in a license in similar circumstances. I could be charged with conducting an IFR flight without the appropriate rating.
