Can anyone tell me what are the implications of "Language proficiency: English", which is all it says on my licence? Does this imply level 6, or does this imply that it is as yet unassessed?
Ditto.
In LASORS 2010 the entry is mentioned...
The CAA has complied with the ICAO and JAR
requirements by adding the endorsement “Language
Proficiency: English” to licences issued in the UK where
a FRTOL is also held and/or the licence holder has been
assessed and recorded as achieving Level 4, 5 or 6.
So take your pick, it seems only the EASA licences contain the actual level number but you won't be issued with one unless you have provided evidence. Details on how to get that are in CAP804, Section 4 Part M (page 443). Basically form SRG 1199 needs to end up with the CAA after passing a suitable person to sign it.
I think it reads that if you have any kind of test or check in the past few years your examiner should have completed the form and sent it in. The only way to know for sure is to contact the CAA and ask them I guess?
