A new turbulence detection system using NEXRAD Doppler radars provides real-time snapshots of turbulence to pilots, helping them avoid hazardous areas. The system's accuracy is reported to be high, with pilots praising its ability to provide accurate information about turbulence location and intensity.
The AIAA will present several awards at the upcoming conference, including the Wyld Propulsion Award to Frederick Boorady for his contributions to liquid propulsion technologies. The Ground Testing Award will be given to Frank Steinle for his work in experimental aerodynamics and ground testing.
A team of Stanford researchers conducted the first comprehensive survey of the USS Macon's final resting place, a 1,000-foot-deep site off Monterey Bay. The airship was one of only two 'flying aircraft carriers' ever built and went down in 1935 without seeing combat.
Researchers have developed a rapid testing method, PASD, to diagnose and repair intermittent faults in aircraft wiring harnesses. The technique uses a high-voltage pulse to detect small insulation breaks, allowing technicians to locate and fix faulty wires efficiently.
A Johns Hopkins Medicine study found that pilots with a DWI history have a 43% higher crash risk than their counterparts without one. The researchers analyzed over 300,000 pilots and tracked their flying records, concluding that background checks can effectively predict and prevent crashes.
A new system will be tested at Denver International Airport to detect freezing drizzle and prevent engine damage. The system can identify the hazard more accurately than visual observation, which often goes undetected due to small droplet size.
Researchers at LSU are working on developing a better aircraft self-diagnostic system that can detect problems earlier, recommend the best course of action, or take control of the flight. The goal is to improve flight safety and reduce the risk of accidents.
Researchers propose using plain language and better organization to present Notices to Airmen (NOTAMs) to pilots. This could help reduce confusion and improve flying efficiency, leading to increased safety for pilots and passengers.
National Institute of Standards and Technology (NIST) researchers have developed a new metal-stamping test station with an X-ray stress measurement system. This equipment enables detailed maps of stresses and strains as sheets of steel and other metals are punched, stretched or otherwise shaped.
A study of 3,306 pilots found that those with over 5,000 hours of flight experience had less than half the risk of a crash compared to less experienced counterparts. The study suggests that flight experience, not age alone, is a crucial factor in determining pilot safety.
Dr. Arnold Barnett argues that large US airlines prioritize security measures over terrorist threats, despite evidence of two major aviation-related terror attempts in the year following 9/11. New low-fare airlines, such as jetBlue and Spirit, are willing to implement voluntary security measures.
The Reduced Oxygen-Breathing (ROB) device induces symptoms of hypoxia in a normal room at normal air pressures, reducing the risk of decompression sickness and pressure trauma. This cost-effective training tool will be used for periodic hypoxia familiarization training for naval aviators.
Researchers developed a Web-based display, CIP, to describe current icing conditions, which goes into service this week for meteorologists and airline dispatchers. A companion tool, FIP (Forecast Icing Potential), forecasts potential icing up to 12 hours ahead but is still in development.
The Office of Naval Research is testing a new weather radar system that delivers potentially superior at-sea weather information. The system, which uses the Navy's SPY-1 phased array radar, will provide direct weather feedback and input to tactical weather forecasts.
The Aerosonde successfully completed the 2,000-mile, 26-hour trans-Atlantic flight, becoming the smallest aircraft to cross the Atlantic. The achievement marks a significant milestone in autonomous aviation and demonstrates the potential of unmanned aircraft as workhorses for the next century.
The Heli-STAR project successfully tracked helicopters operating in large metropolitan areas using GPS equipment, providing low-altitude traffic control and cargo delivery services. The technology showed promise for addressing transportation challenges in urban areas.
The Federal Aviation Administration (FAA) has certified a new aircraft repair technique, using a bonded composite doubler, for Delta Airlines' L-1011. The patch reinforces the plane's right mid-section access door and has proven to be effective in reducing maintenance tasks.
Researchers highlight the ongoing threat of ice on small plane wings, which can compromise control and safety. Despite a redesigned deicing 'boot', other aircraft and severe icing conditions remain a concern.
The Proactive Error Reduction System (PERS) program is a computer program that allows airline maintenance workers to determine why an error occurred and see how other airlines have solved similar problems. It goes beyond current error-analysis by being proactive, examining all the things that led up to the error.
