LASORS is the stuff delegated under the UK ANO to the CAA. What happens in say Germany?
What exactly does the ICAO IR preserve? AIUI, it preserves all the theory exams, so a BA ATP going to work in the USA for 15 years can come back, do a brush-up etc, and work for BA again. But what if you fly on an ICAO IR (privately, though I do actually have an FAA CPL/IR) for 10 years, during which you have not renewed your JAA IR? Can you renew the JAA IR with just a normal IRE, or is it a fresh new IR flight test (currently with a CAA staff examiner though this is changing)?
