Thanks I-ford, I think you're the first to see my point.
Approaching minimums, as you quoted, as per the 'numbers' the aircraft does meet the minimum requirements, as follows......
2500ft runway, 600ft displacement, 1900 ft 'available'. 70% of 1900 is 1330. The aircraft in question requires ~1200 as per the manual. (although this is next to impossible).
I'm in full agreement that where you are it might be prohibited, but do you have any documents that clearly state this regulation? If you do, please send me a link.
Also, regarding ATC not filing reports, there is obviously a reason. Possibilities are that it's either not illegal (as in Canada), or they don't wish to close the airport. If they were to file reports on every single aircraft that lands (like I mentioned earlier, ever single aircraft at this airport lands before the displaced threshold), I have to assume that this would effectively close the airport.
I get the impression that alot of people here think that it's just one ignorant pilot landing before a displaced threshold for no reason. I assure you that is not the case. It is every single pilot, every single landing. All nationalities, all registrations. Chief Pilots, training captains, and CAA examiners. That has to be hundreds if not thousands of pilots over the years. Statistics would suggest that we can't all be ignorant psychopaths.
