This is the 11th in a series of articles looking at the impact of the Next Generation Air Transportation System (NextGen) on GA pilots.
Sounds like a sale doesn’t it? Well, not really. Instead, it’s a reference to the FAA’s decision as part of the Next Generation Air Transportation System (NextGen) to use two different “systems” within the ADS-B environment, so everyone on both sides of the aisle would be happy.
This is how it came down: The big boys on top, the transport carriers, have been using the newer Mode S 1090ES (Extended Squitter) transponder system that we discussed last month for some time know. Perfectly understandable since they have all the necessary attributes to work in the proposed ADS-B system environment.
But — don’t you just hate those buts? — the Mode S transponders have some limitations.
