Don't waste your time.
You could take a calibration certificate 15 seconds old together with a certified letter from the designer and original equipment manufacturer, signed in blood, with a guarantee that he would hand over all his worldly possessions and sacrifice his youngest daughter to the God of Aviation Regulatory Madness, should it be found to be out of calibration to 0.0000000000000000000001% and they still wouldn't accept it.
If it does not happen at the hallowed turf that is Aviation House Aeromedical Centre, as dictated by certain egoistical individuals, full of their own self-importance and not willing to accept the opinions of real-world time-served experts from the same industry with decades of real life experience (and not in the narrow-minded and massively restrictive artificial world of aviation regulation), then it will not be accepted......simple as that.....
......UNLESS the sweeping and very welcome changes (not quite as welcome at Aviation House though!) imposed on other CAA departments by Andrew Haines have managed to permeate the resistance-to-change armour surrounding the Medical Department. We can but hope!!!
