Could NextGen be hacked?

Computer security experts worry that the Next Generation Air Transportation System, known as NextGen, is vulnerable to hackers. Reporters from NPR talk to one hacker who says he could place “ghost planes” in the system, essentially causing chaos. They quote him: “If you could introduce enough chaos into the system — for even an hour — that hour will ripple though the entire world’s air traffic control.” Check it out here.

Avidyne joins MIT, FAA in ADS-B development program

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.
