the actual fee, when implemented, will likely be less than the current
£630, because is will be more difficult to justify that it corresponds to the
true cost of a briefing, especially if it is a mere online application, and that
the costs are incurred in surplus of what they normally have to spend on
briefing the existing UK CAA examiners.
Let's also be clear there is absolutely no comparison between the fees the CAA would charge a UK examiner and the "briefing" for a non-UK examiner. The content of the latter is restricted by Part FCL to "
a briefing on the national administrative procedures, requirements for protection of personal data, liability, accident insurance and fees. "
The whole point of European standardisation under EASA is...errr...that European FCL is standardised. Whatever the CAA charge £630 for to a UK examiner will have been conducted by the NAA of another country for their own examiners in fulfilment of the Aircrew regulation. Thus the CAA briefing is restricted to the very narrow subject matter in the quote above.
