The plans for my aircraft include a german ADS-B receiver and the power Flarm system all presened on the G500 screen, at about 1200 Quid it is a bargan.
The big hole in the system is made by the idiotic EASA attitude that demands the £15K certification of an system already certified for other light aircraft.
So when I get the whole thing done the aircraft will have a full FLARM system to keep me and the very hard to see gliders apart, I will see ADS-B equiped aircraft but thanks to EASA these aircraft wont be able to see me.
Perhaps I should write to the director of EASA and ask him how EASA sees this STC policy in terms of their safety mandate.
