Thanks for the pointers Shawn and gnz,
I have had a good idea
The post-STC performance or the F2 is as near as dammit that of the AS355N, which is what the aim of Eurocopter was when they conceived the STC. Eurocopter have already cited the "N" figures to the FAA to justify many elements of this STC already. As I can show by OEI hover OGE and climb rate figures that the performance is identical or even better in some cases, to the "N", this should not pose a problem.
This uses existing approved data and removes the need to justify the figures! If this fails then I will have to re-hash the existing figures.
gnz, you seem to be in the south of france, I am in the Charente, get in touch if you want.
