M' reg filed under 'N'...I smell ramp check all over that!
Why do you say that? IOM register provided a "Certificate of Commerciality" as we provided evidence the aircraft is being used for genuine business reasons. We were thus flying non-scheduled commercial flight - hence N. We were never ramp checked as a result of what he had filed.
I am curious to know what you consider is correct use of "N", if not this case?
