I do find it somewhat amusing that ADSB was to be the be-all-end-all solution. There was a mad rush to implement it and mandate it and the push for manufacturers to hit the market with low cost ADSB-out devices, with everyone thinking that ATC would magically guide us all to a safe flight.
Now after the first mid-air tragedy, all of a sudden everyone realises that OUT is useless without IN and that ADSB-in devices are next big thing.
The issue is the lack of devices available to fit into the fleet. It’s great to have one of the two EFB’s, however you still need an ADSB-in device and that’s not simple. So we go and fit a $10,000 certified out solution and have to buy a $900 Skyecho and IPad to receive traffic to save our own butt as ATC can’t do it for us.
There are some units that will hook into the EFB’s without having to buy more kit, but they aren’t cheap. Dynon have a good ASDB-in solution, however that requires a lot of costly components and isn’t going to work for your average flying school.
