The ADS-B system that is the cornerstone of the FAA’s NextGen ATC modernization plan is at risk of serious security breaches, according to Brad Haines, a hacker and network security consultant who is worried about ADS-B vulnerabilities. Haines first outlined his concerns during a presentation he gave at the Def Con 20 hacker conference in Las Vegas in July.
Secondary surveillance radar
An Aviation Rulemaking Committee (ARC), tasked by the FAA to advise on ADS-B in introduction strategies, has recommended that the system not be mandated. In large part, this is because many of its potential applications have yet to be fully defined so the benefits payback period on an operator’s investment in the near future would be well outside the typical three-year standard for the major airlines, considered the system’s predominant user group.
Avidyne announced a new mode-S transponder that will make upgrading to ADS-B out capability much simpler. The new AXP340 mode-S transponder is a slide-in replacement for the popular Bendix/King KT76A and KT78A Mode A/C transponders. Retailing for $5,995, including connector kit and mounting tray but not antenna, the AXP340 will be available early next year, in plenty of time to meet the 2020 ADS-B out mandate.
Corporate operators heading for Colorado’s Craig, Steamboat Springs, Hayden and Rifle Airports this winter shouldn’t worry about diverting to Denver and having their passengers complete the trip by car. That’s because the Colorado DOT has purchased and installed a $5.7 million Sensis multilateration system to track aircraft accurately well below the mountain-affected line of sight of distant FAA secondary surveillance radars (SSR).
Brazil’s Cenipa accident investigation bureau has issued its report on the September 2006 midair over the Amazon, along with an NTSB dissent.
A Lufthansa Boeing 737 recently became the first aircraft to use mode-S capability to transmit its radar identification (flight ID), without the use of a secondary surveillance radar (SSR) code. The 737 flight crew was able to automatically correlate the aircraft’s electronic flight plan data by entering a 24-bit code into the aircraft computer.
A Lufthansa Boeing 737 recently became the first aircraft to use Mode S capability to transmit its radar identification (flight ID), without the use of secondary surveillance radar (SSR) code. Rod Marten, who oversees mode-S operations at Eurocontrol, said that air traffic controllers typically assign a four-digit SSR code to a target on the radar screen then manually correlate the aircraft information with the electronic flight plan data.
Automatic dependent surveillance-broadcast (ADS-B) has emerged as what many describe as the surveillance technology of the future, but Asia Pacific air navigation service providers (ANSPs) are already taking advantage of its capability and cost-efficiency.
The Colorado Department of Transportation has launched a new technology initiative that will provide enhanced surveillance, and thereby improve access, to its many mountain airports. Currently, IFR flight operations at those locations are limited because surrounding mountains block the line-of-sight signals of the FAA’s ATC secondary (transponder interrogating) radars, preventing the monitoring of lower-level arriving and departing traffic.
Phase One of a proposal by the UK Civil Aviation Authority (CAA) to improve airspace capacity will require aircraft owners in the UK to upgrade to a Secondary Surveillance Radar (SSR) Mode-S transponder by March 31, 2012. In addition, all new installations of SSR transponders must be Mode-S compliant beyond March 31 next year.
