The X-45A unmanned combat air vehicle (UCAV) technology demonstration aircraft completed its first flight in late May at NASA’s Dryden Flight Research Center, Edwards AFB, Calif. The 14-minute flight reached an airspeed of 195 knots and an altitude of 7,500 feet. The first flight of the Boeing-built vehicle exercised basic functions, such as the command and control link between the unmanned aircraft and the ground mission control station. The government team includes the Air Force Research Laboratory, the Defense Advanced Research Projects Agency (DARPA) and NASA.

UCAV might "be able to blur the boundary a little bit between mission processing and vehicle management [avionics]," says Don Winter, director of open systems architecture at Boeing’s Phantom Works Division. Such coupling, exploiting shared resources, isn’t possible with manned aircraft, where a "hard firewall" is required between safety-critical and mission-critical systems. UCAV, like the AV-8B, has adopted an open systems approach, using commercial software standards and tools for mission code, under Boeing’s Bold Stroke initiative.

The Air Force plans to fly a second X-45A later this year, leading up to multi-aircraft flight test demonstrations in 2003. Additional tests will explore the limits of unmanned, coordinated combat operations, culminating with a group UCAV/manned aircraft exercise in fiscal year 2006.

Falcon Satcom

Dassault Falcon Jet has flight-tested high-speed satcom (via Inmarsat Swift64) in the manufacturer’s Falcon 900EX demonstrator aircraft. It plans to offer the Teledyne Controls/EMS Technologies high-speed data (HSD-128) configuration to corporate customers and the fractional market, as well as to develop customized solutions for in-service aircraft using Aero H/H+ antennas. The current configuration uses EMS’ AMT-50 high-gain antenna system. The HSD-128, with 64-kilobit/sec (Kbit/sec) and 4.8-Kbit/sec voice options, permits clearer calls, compared with current 2.4-Kbit/sec satcom technology. The installation also supports four simultaneous Internet users. Dassault is working with EMS Technologies to transition to next-generation Inmarsat services, offering connection rates of up to 432 Kbits/sec. Visit

FAA Security Fund

The Federal Aviation Administration (FAA) announced plans in May to disburse the $100-million fund appropriated by Congress for security improvements to aircraft flight decks and cabins. Eleven carriers were to receive about $3 million under a pilot program to provide video and other technology in the cabin and to implement fixed or mobile (crew-carried) emergency alerting systems. Recipients were to be American Trans Air, Astral Aviation (Skyway Airlines), Chautauqua Airlines, Continental Airlines, Delta Air Lines, JetBlue Airways, Pacific Southwest Airlines, Piedmont Airlines, Sun Country Airlines, United Airlines and Vanguard Airlines. The remaining $97 million will fund carriers’ strengthening of flight deck doors. As of late May, FAA was expecting designs from Boeing and Airbus to be submitted for approval. Airlines face a deadline of April 2003 for door installations and a limit of about $13,000 per aircraft. Visit

South African ATC

South Africa’s air traffic services provider, Air Traffic and Navigation Services (ATNS), has signed on Thales ATM to modernize the country’s air traffic control (ATC) facilities. The contract is understood to be the largest ever awarded by ATNS for ATC modernization. The South African Advanced Air Traffic Control System (SAAATS) program involves the installation of two Eurocat ATC centers controlling three flight information regions (FIRs): the Johannesburg area, the Johannesburg Oceanic area, and the Cape Town area. SAAATS is a major building block in the South African Future Air Management Efficiency (FAME) program, which seeks to "rationalize" South African airspace. Visit

Network-Centric Warfare

The U.S. Naval Air Systems Command (NavAir) announced that it is equipping the E2-C Hawkeye 2000 with the new Cooperative Engagement Capability (CEC) system, furthering the concept of network-centric warfare. CEC, already operational on some Navy ships, networks combatant radars and other sensors, allowing surface platforms to see an accurate single integrated air picture (SIAP) of potential threats in real time. The Navy conducted tests in May on the airborne early warning and control aircraft to evaluate the interoperability between CEC and data links. Additional testing will continue at the Patuxent River, Md., NAS through the fall of 2002; the system is expected to be deployed with the Nimitz battle group later this year. Visit

The Pitch for PRMs

If we installed the precision runway monitor [PRM] at 12 airports, we could realize 35,200 hours of delay savings a year," said Duane Orth, Raytheon’s business director-air traffic and tactical terminals, in a Washington briefing. "Over 20 years, that’s a savings of 700,000 delay hours and $4.7 billion in costs. The payback for a PRM is about 14 months." PRMs cost about $8 million, plus installation, spares and training, he added. The delay savings largely would come from facilitating parallel approaches to closely spaced runways.

Raytheon already has orders to install PRM systems at six airports in the United States. The company believes the Federal Aviation Administration (FAA) should buy more of the surface surveillance radars, arguing that the record number of flight delays of 2001 prior to Sept. 11 probably will return sooner than the 18 months (from 9/11) that has been estimated.

"The issues that prevented closely spaced parallel approaches have been resolved," Orth added, referring to decisions made by the Closely Spaced Parallel Approach (CSPA) steering committee, led by the Air Transport Association of America (ATA). Procedures for these approaches, which the committee has been working on since late 2000, have been established and agreed upon by ATA, FAA, Air Line Pilots Association (ALPA) and the National Air Traffic Controllers Association (NATCA).

FAA requires that, under instrument flight rule (IFR) conditions, runways must be separated by 4,300 feet (1,310 meters) to allow parallel approaches. However, with a PRM on the airport and a 3-degree ILS offset, the separation can be reduced to at least 3,000 feet (914 meters). This, Raytheon contends, would greatly increase capacity at airports, such as New York’s John F. Kennedy (JFK) and Philadelphia, and already increases capacity at Minneapolis and Sydney, Australia.

Gene Austin, Raytheon’s PRM program manager, described other procedures that could be performed with the surface radar, including triple simultaneous approaches at, for example, Atlanta Hartsfield Airport. He said the PRM would allow simultaneous offset instrument approaches (SOIA) and along-track separation (ATS) at airports with parallel runways that are as closely spaced at 700 feet (213 meters). SOIA will first be applied at San Francisco Airport (SFO), which will start operating a PRM this year, according to Austin.

Other PRMs will become operational in 2002–Philadelphia (scheduled for July) and JFK (third quarter). They will join systems operating in Minneapolis, Sydney, St. Louis and Hong Kong. Other PRM targets are Cleveland, Boston, Los Angeles, Newark, Chicago, Seattle, Pittsburgh, Las Vegas, Detroit, Miami, Charlotte and Baltimore.

How can the PRM support closely spaced approaches? The key is rapid radar return updates–up to five times faster than conventional radar systems–using electronically scanned radar technology. "A controller can literally ‘see’ the airplane fly," as opposed to viewing intermittent, five-second updates, Orth claimed. With about a 32-nautical mile range, the radar creates "non-transgression zones," Austin added, referring to them as "guardrails in the sky." With the rapid updates, controllers can give pilots a 10-second advanced warning of a possible transgression, or "blunders," he said. Visit
