Pentagon officials say the new government of Chile, faced with a Jan. 7 deadline to sign the deal for 10 Lockheed Martin F-16C/Ds, two KC-135 tankers, spares and training, has asked for and received a 30-day extension. That will allow the incoming administration of President Ricardo Labos to get its feet on the ground and familiarize itself with the $700-million deal. It would be the largest U.S. arms sale to Latin America since the 1983 sale of 22 F-16s to Venezuela.
Singapore police said last week that they had arrested 15 people in December from a clandestine organization called Jeemah Islamiah. Several others are said to have fled the country. They were detained under Singapore's Internal Security Act, which empowers police to hold them for at least 60 days. Malaysia has a similar law. Police said they seized detailed information on bomb-making as well as photographs and video surveillance of potential U.S. establishments, including the U.S. embassy. Jeemah Islamiah's activities include fund raising for terrorist groups.
SINCE THE EARLY 1980s, operators flying under FAR Part 135 in Alaska have had the highest number of accidents involving controlled flight into terrain (CFIT). According to the Flight Safety Foundation (FSF) and the U.S. National Transportation Safety Board, about 30% of accidents involving Part 135 operations in the 50 states occur in Alaska. An informal survey found that pilots are often under extreme pressure to fly in marginal weather conditions.
Wilson LT is a polypropylene-based material used to create lightweight shipping cases. Construction is nondirectional, without the directional grain that can lead to weak spots. The material is reinforced with talc for rigidity. It is moisture resistant, UV tolerant and chemically inert, making it suitable for transport and storage of all types of equipment. The light weight also helps to reduce shipping costs. The cases are constructed with heavy-duty locks, reinforcements and hardware similar to that used on standard plywood cases. The material can be recycled.
London-Luton based low-cost carrier EasyJet is touting a major fleet expansion plan, with up to a further 75 aircraft to be acquired by 2007. If an order for 75 aircraft is concluded, it is estimated to be worth around $3 billion and would more than double the size of the EasyJet fleet. The airline is in discussions with Boeing and Airbus, with the 737-700 and the A319, respectively, the two types under consideration. EasyJet presently operates an all-Boeing fleet of 18 737-300 and nine 737-700 aircraft.
In a swirl of legislation and Pentagon memos that included at least two major misunderstandings, a $1-billion effort to build a joint-service family of signals intelligence systems that could be plugged into a range of aircraft has foundered. But U.S. Air Force officials promise they soon will resurrect the program.
The DGx high-resolution digital recording system captures, compresses and stores images up to 1280 X 1024 pixels. Computer, radar, video and audio acquisition, time code and even markers are supported by this system. Designed for applications in simulation and training, command and control, and monitoring, the unit accepts up to four image sources for recording to digital tape or disk. Inputs may be computer, radar and other high-scan-rate video signals. Each image's original resolution is preserved.
THE EUROPEAN JOINT VENTURE COMPANY, Sostar GmbH., will develop the new European all-weather ground surveillance system for the governments of France, Germany, Italy, the Netherlands and Spain. The stand-off surveillance and target acquisition radar (Sostar) will use an active electronically-scanned array for manned or unmanned surveillance of large areas, for crisis and conflict management. The goal is to detect and track slow-moving targets and to provide high-resolution imaging and classification of fixed targets.
Boeing and the U.S. Air Force are nearing a deal for 60 more C-17s, but a move to augment that force with a commercially operated version of the airlifter has slowed. Negotiations for the next multiyear C-17 contract are about 90% complete, said Col. Ted F. Bowlds, program executive officer for airlift and trainers. The deal, estimated at more than $9 billion, will maintain the C-17s current production rate at 15 aircraft per year until the service has bought 180 transports--the existing contract will bring USAF's inventory to 120 aircraft.
The $5 Billion Misunderstanding, The Collapse of the Navy's A-12 Stealth Bomber Program, by James Stevenson, recounts the events that eventually led to the stealth bomber's cancellation. Stevenson cites many examples of the mismatch between perception and reality experienced by Navy program managers, the Defense Dept., Congress and the contractors.
GEORGIA TECH RESEARCHERS have demonstrated the first circular atom storage ring--a step that could lead to much more accurate gyros and navigation systems for aerospace. The concept is analogous to fiber optic gyros, but would detect changes in motion using atom instead of optical interferometry. Improved performance would result because the sensitivity of any given-size interferometric gyro is proportional to the mass of the particles, and the mass of an atom is about 10 orders of magnitude larger than a photon.
The Model BS-112 miniature linear gage sensor can measure dimension, thickness, curvature, eccentricity, displacement, height, depth, flatness, run-out, roundness, distortion, deflection and position. It produces measurements of 0.00004 in. with a range of 0-10 mm. The sensor was built to fit extremely tight quarters where conventional sensors are impractical, and can be mounted inside of machinery with limited access space. The sensor has a waterproof seal, and a dust bellow is included for additional protection in harsh environments. Included is a 6-ft.
A tracker can be useful for three-dimensional pointing, simulation, computer-aided design and other aerospace tasks. Ascension Technology (www.ascension-tech.com) has come out with pciBIRD, a six-degree-of-freedom magnetic tracker with a processor card that plugs into a PCI slot in a personal computer. The sensor works within a 3-ft. radius from a magnetic transmitter base station, and provides real-time position and angle information at up to 105 measurements per second. Resolution is 0.02 in. and 0.1 deg., and absolute accuracy is 0.07 in. and 0.5 deg.
A soft business jet market will cost about 800 Bombardier Aerospace employees their jobs. The company expects to cut about 550 people at its Tucson Completion Center, which works on various Bombardier business jet models, and about 250 people at its Wichita factory that assembles Lear 31A, Lear 45 and Lear 60 business jets. The workforce reduction will take place over the next 12 months.
British air traffic management provider National Air Traffic Services (NATS) is pushing to be allowed to modify planned reductions in en route charges as a result of the post-Sept. 11 commercial air travel downturn. Under a deal hammered out with the U.K. Civil Aviation Authority (CAA) in mid-2001, NATS en route charges were to be cut by 4% in 2003, followed by further cuts of 5% in 2004 and 2005. As a result of the traffic dropoff, NATS will apply to the CAA later this month to reevaluate the pricing structure, a process expected to take three months.
Malaysia Airlines said it expects to raise 5.6 billion ringgit ($1.5 billion) from the sale of six 747-400s and two 777-200ERs in a lease-back agreement to raise cash to pay down debt.
There are many books available on aircraft to be found in dusty bins and as new editions in book stores. As an aircraft enthusiast, I have looked at many of these over the years. Some are so weighted down with technical detail, they are only used for reference. Other books discuss specific aircraft and their attributes, but often do not give you a sense of history. And as we all know, every aircraft flying has tales of challenges, woes and triumphs following in their slipstream.
FAA Administrator Jane Garvey is just as averse to letting up on efforts to manage aviation demand as she is on backing off from those to expand capacity. Announcing revisions--but no slowdown--of her agency's 10-year plan to improve air traffic control systems and procedures (AW&ST Jan. 7, p. 22), Garvey said it's time to resume deliberations toward market-based demand-management measures at airports--congestion and peak-hour pricing, slot auctions and the like. The agency sought public comment on the issue last Aug. 21 but suspended the Nov.
BOEING PHANTOM WORKS has evaluated a solid state cooling technology that could offer lighter, more efficient, localized cooling in the future, and has taken the right of first refusal for aerospace applications, according to research and development company Borealis Exploration Limited. Borealis' Cool Chips thermal-management approach uses a form of a vacuum diode, that pumps heat from one side of the chip to the other for localized cooling. The thermionic technology delivers up to 80% of the maximum theoretical (Carnot) efficiency for heat pumps, according to Borealis.

Information is at www.hanleyinnovations.com. . . . Los Alamos National Laboratory has selected Oracle Corp. to provide an enterprise resource planning system. The contract is worth $4 million over four years, and the lab plans to hire an external integrator to work with the ERP project team.
The rail-type universal machining center is equipped with a high-speed, five-axis spindle head. Aerospace manufacturers using the machine include GenMech Aerospace and Precision Metalcraft, both of which produce primary aircraft structures. The unit features a traveling gantry for machining of extra-long aircraft components such as spars and stringers. The cast iron crossrail and ram provide 100 in. of Y-axis movement and 39.4 in. of vertical Z-axis movement. Continuous 360-deg. C-axis keeps the spindle in-cut without running out of C-axis or waiting for C-axis to unwind.
Robert H. Gray who was the NASA launch director or deputy director for 178 space missions flown from Vandenberg AFB, Calif., and Cape Canaveral and the Kennedy Space Center, Fla., died at Cape Canaveral Hospital Jan. 8. He was 78. The launch operations he headed included five manned Apollo and Skylab flights. Gray retired from NASA in 1986 as Kennedy's Space Station and Advanced Projects manager after also serving as Kennedy's director of Unmanned Launch Operations and then head of the Shuttle Projects Office during the early years of the shuttle program.
The Multiplex 6100Y--the Y-axis drive is integrated in the turret's movement--brings together two spindles, two turrets and a turn/mill center in order to machine workpieces complete in a single setup. The twin-opposed spindles can work independently or continuously on the same workpiece to complete first and second operations. With the addition of the integral Y-axis, it can cut perpendicular to the spindle giving it machining capabilities such as drilling, milling or tapping on or off the centerline.
