I discussed the following with the relevant policy chap at the CAA, concerning dual-licensed UK and EASA instructors providing instruction at a UK-based ATO/DTO for UK and EASA licensing:
1. Will instructional flight time achieved by EASA Part-FCL instructors providing instruction for EASA licences be acceptable towards UK Part-FCL flight instructor revalidation criteria?
2. If an instructor can find a dual-licensed FE, would a single assessment of competence flight be acceptable for revalidation of both UK and EASA instructor certificates?
3. Would the requirements of FCL.910.FI(c) to remove FI restrictions for a UK Part-FCL FI be accepted by the Authority if gained whilst instructing EASA Part-FCL applicants?
The answer in all cases was YES.
