Just to clear up one point, you cannot do an ATPL flight test with an examiner other than one from CAA unless you work for a company that has an approved examiner and ATPL flight testing on their 119 certificate.
As a flight test NZ examiner with ATPL testing approval I cannot do the test.
Not sure why this is but makes to tough for anyone who does not work for an airline.
We have tried to work with CAA on this one but no luck so far.
Then they wonder why everyone goes to Aussie does it over there then changes the licence via the TTMRA!
