Just stating a vague "she'll be right after 100 hours of random testing" really demonstrates safe operation. Not!
Umm, I think you're off the track. Just re-read what I wrote and tell me where I said it shouldn't be thoroughly tested. You have to remember that the system we are talking about is simply a relay. It is taking the output of a certified GPS system in an aeroplane and relaying that output to ATC. From a functional perspective, it is as if the pilot was reading his GPS coordinates over a radio to someone on the ground, and the person on the ground then telephoning those coordinates to someone in at ATC centre. Perhaps you could tell me how much verification and validation is required to certify such a system?
