SS - that's the total including the £595 diesel. Original post modified slightly to clarify.
Whopity - an interesting area! Obviously I'm biased, and the intent may differ, but that is not what it says in plain English. FCL.1030 (a) uses the wording "when conducting". If they meant to state that 45h should be completed before the test, they should have used "whilst conducting", or indeed "before commencing" as they use "after completion" in FCL.1030 (b).
As the skills test covers an extended period, "when" in this context implies "at any point during the conduct of the test". It does appear to preclude
completing the test before you have 45h, but as I hit that point 50m before the end of the test this is no problem.
The application form of course contains a declaration by the examiner to the effect that the experience requirment of FCL.1030 has been met, but this is filled in after the test, hence again no problem.
The CAA did not seem to have any issue with it when the logbook was sent in anyway
