Wilbrecht Electronics' metal foil resistor, Type MAQ, was designed to handle external mechanical stresses by the lead movement and vibration occurring in aerospace, aviation and military applications. The Type MAQ's two-wire lead construction provides increased stability against vibration and abates mechanical stress from external forces and pulsation. Also, the resistor incorporates a high-purity, alumina ceramic substrate and proprietary Ni-Cr alloy foil system for ultra-low TCR. It is approved for both MIL-PRF-55182/RNC90Y (R level) and NASA specification S-311-P-813.

The two planned derivatives of the Boeing 777--which will bring the total models to five--are approaching milestones that will fix the wide-body transport on a new course to becoming one of Boeing's most successful niche aircraft. In the explorations during the design phase, the 777-200LR (longer range) and the 777-300ER (extended range) are coming in below the specification operating empty weight, promising either greater than originally planned range or improved payload capability for each aircraft, said Lars Andersen, program manager.
Acting National Transportation Safety Board Chairman Carol Carmody voiced disappointment at an FAA committee finding that the costs of implementing fuel tank inerting systems would outweigh the safety gains. After TWA 800's catastrophic fuel tank explosion in 1996, the board urged carriers to begin injecting nonflammable gases into fuel tanks to prevent vapors from igniting when exposed to heat sources or electrical problems. Since then, two other large passenger jets have been destroyed by fuel tank explosions.
Airports Council International reports that April cargo traffic decreased 9% while passenger traffic rose 3%, compared with the same month last year. Cargo volume carried decreased 13% in North America, 7% in both Asia/Pacific and Latin America/Caribbean regions, and 4% in Europe. The exceptions to the negative trend caused by an economic slowdown are Beijing, showing a 16% increase in cargo volume; Sydney, with 10% and Dubai, 6%.

More than 400 standard ovens are featured, including all types for laboratory, industrial, and Class 100 cleanroom for heat processing applications. Custom heat processing and heat treating equipment capabilities are included, as well as a ``virtual tour'' of Grieve's plant. Dozens of standard furnaces with operating temperatures to 2,200F are described.
The Galileo spacecraft made the first polar magnetic measurements of Io on Aug. 6, which will help determine whether the Jovian moon has its own magnetic field. Prior Io approaches went by the equator, and the 200-km. flyby of the north pole should help separate an intrinsic field from one induced by Jupiter's varying magnetosphere. The spacecraft is in generally good health, but at least nine of the 16 camera observations were ruined by a recurring electronics problem (AW&ST June 4, p. 38). The next Io flyby is set for Oct. 16, over the south pole.
Hoping to overcome environmental objections, San Francisco International Airport (SFO) officials have scaled back the amount of fill that their most intrusive runway proposal on San Francisco Bay would require. But the Sierra Club and other opponents still regard any airport expansion plan that enters the Bay as unacceptable.

The Civil Aviation Administration of China has worked for years to improve a national airline industry dogged by overcapacity, reckless price wars, heavy debt and poor services. But the industry's financial performance for the first half of the year shows the CAAC hasn't found the formula yet, especially in terms of yield management. The 20 carriers under its financial supervision racked up a cumulative 2.23-billion yuan ($285.9-million) loss for the period.
The FAA is proposing an airworthiness directive that would require correction of faulty circuitry on the Garmin GNS 430, an integrated navigation and communication system installed in some 1,985 general aviation aircraft stateside. Yet, two years ago, the company notified the FAA when it discovered a few instances of inaccurate course deviation indications on instrument approaches. The problem was traced to one vendor's components, which met specifications, but in some instances led to a faulty indication for the pilot.
Richard Alena of NASA's Ames Research Center and Dan Duncavage of the Johnson Space Center have developed a laptop diagnostic tool for the International Space Station. The Databus Analysis Tool (DAT) monitors status and command message traffic between on-board control computers and major subsystems, including the station's solar arrays, docking ports and gyroscopes. The diagnostic tool is integrated into an off-the-shelf Pass 1000 system from SBS Technologies, which includes analysis software and a hardware interface in a PC card format.

The FAA proposed a $50,000 civil penalty against Sikorsky Support Services, charging that the company violated hazardous materials regulations by shipping three aviation fuel control units containing residual amounts of flammable liquid. FedEx received the units last Oct. 30 and carried them by air from Alabama to its air cargo facility in Albuquerque, N.M., where an FAA special security agent found on Nov. 2 that leaking fuel had saturated a corner of the shipment's outer packing, the agency said.
