One of the air traffic management systems least well known to pilots is multilateration, sometimes called MLat, or multilat, or WAM (for wide-area multilateration).
Traffic Collision Avoidance System
General Atomics Aeronautical Systems (GA-ASI) said that an improved version of the Gray Eagle UAV flew for 45.3 hours on a demonstration flight earlier this month. The Gray Eagle was developed for the U.S. Army from the Predator UAS. The Improved Gray Eagle is a higher-power, higher-mtow version that GA-ASI developed using company funds, although the U.S. Army paid for the demo flight, the first of two planned by the end of the year.
With the announcement that Garmin plans to certify a G5000 flight deck in the Beechjet 400A and Hawker 400XP, Elliott Aviation is demonstrating the system in a mockup at its NBAA booth (No. C8143). Elliott Aviation has already completed 100 King Air G1000 retrofits and sees the G5000 program as a way to allow Beechjet operators to keep flying their jets indefinitely.

Extension of Comment Period on Use of Enhanced Flight Vision Systems (EFVS) and Pilot View Requirements for Vision Systems
While the FAA mandate to install ADS-B out equipment for aircraft flying in U.S. airspace by Jan. 1, 2020 is more than six years away, aircraft operating in some countries’ airspace must be compliant starting this December. Avionics manufacturers are ready with equipment to meet the mandates and avionics shops and aircraft manufacturers are working on supplemental type certificates (STCs) to smooth the path for upgrades in many business jet types.
The Australian Transport Safety Bureau continues to investigate a September 20 incident 10 miles west of Adelaide in which two Airbus A330s flew too close to one another. One aircraft was eastbound at FL390 while the other westbound at FL380. The separation loss occurred shortly after the westbound flight was cleared to climb to FL400, generating a Tcas alert in the eastbound aircraft. The controller on duty quickly cancelled the climb clearance but not before the alert was generated.
A newly updated FAA draft advisory circular AC 20-151B provides flight departments with fresh guidance necessary in obtaining airworthiness approval for traffic alert collision avoidance systems II (Tcas II), as well as for certification of a stand-alone mode-S transponder system.
Garmin launched a G5000 avionics modernization program for the Beechjet 400A/Hawker 400XP, targeted for FAA STC approval in 2015, that will be available at certain Garmin dealers. The company estimates that the glass cockpit retrofit for the light twinjet will cost between $450,000 and $500,000 installed. In addition to modernizing the flight deck, the new avionics package is lighter and thus raises the jet’s useful load by 200 pounds.
Avionics manufacturer Garmin (Stand 2011) is experiencing growing interest in its products from the Brazilian marketplace, which has the second-largest general aviation fleet in the world. Garmin flight decks are prominent in two popular Brazilian business jets: the Embraer Phenom 100 and 300. In addition, many Brazilian operators are choosing the Garmin G950 and G1000 upgrades for Beechcraft King Airs, as well as the Garmin GTN series touchscreen GPS/navigation and communication systems for a variety of aircraft.
Rockwell Collins’s next-generation TTR-2100 traffic alert and collision avoidance system (Tcas II) for transport aircraft has achieved FAA certification. The new system, which provides NextGen traffic surveillance in a lighter and more capable unit, is available for Boeing aircraft as a forward-fit and retrofit solution. Airbus and other aircraft types will follow soon. Both the TTR-2100 and the soon-to-be certified TTR-4100 for helicopters and business and regional aircraft meet the emerging requirements of NextGen airspace.
