The families of victims of the October 1994 crash of an American Eagle ATR 72 into a field in Roselawn, Ind., met October 31 to remember their loved ones and discuss fundraising efforts to build a permanent memorial. All 68 people aboard American Eagle Flight 4184 died in the accident. The pilots lost control of the aircraft after it accumulated a significant amount of ice while flying at low speed in freezing rain in the holding pattern, a problem that triggered an autopilot disconnection while the aircraft was severely out of trim.
Aviation weather service provider WSI (Booth No. C7915) of Andover, Mass. is here at NBAA showcasing the latest updates to Pilotbrief Optima, its flight planning and real-time weather monitoring tool.
Equipment manufacturer Zodiac Aerospace is developing two new in-flight icing detection systems (FIDS). Scheduled to be ready for entry-into-service in 2015, the first system will detect supercooled droplets of less than 50 microns in diameter. This size is consistent with current standards for large aircraft (CS-25, Appendix C under EASA rules).
On Friday, Rockwell Collins unveiled its new EVS-3000 enhanced vision system, which includes a multi-spectral EVS sensor that “significantly improves detection of outside terrain, hazards and obstacles in low-visibility conditions caused by weather phenomena such as fog.” The EVS-3000 also brings the industry-first ability to fully detect LED lighting, which is increasingly being used by airports as a runway lighting solution. It does not require a built-in cooling system, reducing weight.
A June 26 NBAA Webinar delivered new insights into the weather international pilots might encounter across the globe. In addition to a refresher on the potential dangers of the Inter-Tropical Convergence Zone (ITCZ), topics covered included monsoons, dust and sand storms, clear air turbulence (CAT), the jet stream and tropical cyclones.
In response to the powerful tornado that ravaged areas of Oklahoma City on Monday, business aviation charity Sky Hope Network has organized a community relief fund to aid several aviation professionals who lost their homes and also the family of an FAA title examiner who was killed in the tornado. In its first day, the campaign raised nearly $10,000, all of which will be distributed directly to the victims. Donations can be made through June 1 via Sky Hope’s website.
The National Center for Atmospheric Research (NCAR) began a month-long test last week aimed at better predicting when and where thunderstorms might tear their way across Colorado’s Front Range and adjacent Great Plains region. The research uses high-altitude aircraft to improve storm lead times, especially in the crucial six- to 24-hour window before storm formation.
A Beechcraft 1900 on an April 7 ferry flight from Namibia is missing and assumed lost in the South Atlantic Ocean near Sao Tome off the southwest corner of Africa. Neither the pilot, the sole occupant of the aircraft, nor any portions of the airframe have been recovered. Weather at the time of the accident was reported as heavy rain, with lightning and high winds.
As thunderstorm season approaches in the Northern Hemisphere, it’s worth remembering how weather-radar technology has improved in the past three decades. Southern Airways Flight 242, a McDonnell Douglas DC-9, crashed in Pauling County outside Atlanta on April 4, 1977, after flying directly into a severe thunderstorm, calling attention to the then little understood issue of radar signal attenuation in areas of heavy precipitation.
A team of Harvard University researchers has devised a product that prevents ice and frost from forming on metal surfaces such as the leading edge of an aircraft wing.
Surfaces treated with the non-toxic, non-corrosive Slips (for slippery liquid infused porous surfaces) become ultra smooth, slippery surfaces to which fluids and solids alike, such as condensation, frost and even ice, will not adhere.
The Slips technology–tested so far on refrigerator fans–has also been proven to work effectively under high-humidity and high-pressure conditions.
