Aveillant, a spin-off company from France-based technology engineering specialist Altran, is developing a new radar designed to distinguish between aircraft and the rotating blades of wind turbines, eliminating the potential confusion wind farms could cause in ATC and allowing wind farms to be built closer to airports.
Air traffic control radar beacon system
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.
Holland’s recent experience with the consequences of requiring all aircraft to be equipped with mode-S transponders may prompt a revision of similar rules by other national aviation authorities.
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.
Regional airlines and other Part 121 operators may have to equip their aircraft with a switch within easy reach of the pilot or copilot that immediately activates the transponder hijacking code, if a proposed rule is adopted. Although the proposal would apply initially only to airlines, the FAA is asking industry to comment on its appropriateness to Part 91 and 135 operators.
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.
Citation operators this summer can expect to receive Service Bulletins to address European TCAS/ ACAS and upgraded mode-S transponder requirements going into effect early next year.
Raytheon Systems Limited (RSL) has unveiled a new automatic dependent surveillance-broadcast (ADS-B) receiver that uses a 16 MHz or better sampling rate, a new algorithm and enhanced error correction to decode 1,090-MHz extended squitter transmissions correctly even in the presence of extreme frequency congestion.
The next generation of airborne weather radars won’t just see the storms, they will remember what they have scanned and store that information in a computer database.
