Bell Boy
Your 'Uncle' Shawn is absolutely right on cost; formidable, and measured in (a great many) tens of 1000s of dollars, if not hundreds. Bell did a program of Flt Testing for the 430 and unfortunately utilised imperial data for their FM performance section. This, of course, didn't quite meet the SI (metric) system so it all was pretty much for nothing. Lot of very hacked off ppl around
. A great many strenuous conversations ensued

The idea of using the NRC machine is a great one but, as he says, you would still have to get it past EASA/CAA - and the figure there is £180 / hr. PM me if you want an alternative - I know an ex CAA certification man who runs a consultancy. He is MORE than capable, and he doesn't charge £180/hr, however you will still have to fund the hundreds of manhours used by the regulatory types to 'approve' his submission on your behalf.
Pain of the first order that great ideas get strangled at birth
