The Tamdar instrument allows aircraft to sense and report atmospheric conditions automatically as they fly. A satellite transmits the airborne, real-time observations to a ground data center that processes and distributes up-to-date weather information to forecasters, controllers and pilots. The onboard sensor also measures humidity, pressure, wind, icing and turbulence, as well as GPS-derived location, time and altitude data. According to Jay Ladd, the president of AirDat—which makes and supplies the airborne sensor system—regional aircraft are a desirable platform for the sensors because they typically fly below 25, feet and have frequent cycles each day. This application, Ladd said, dramatically increases the number of observations in the lower atmosphere, with the Mesaba experiment contributing daily atmospheric soundings. Contrast this with the data received by a mere 70 weather balloon sites in the continental U. Horizon Air will soon be equipping its regional turboprops with the 6. Ladd added that the package is not limited to the above-mentioned uses because the AirDat system can obtain and process any data flowing over the Arinc busses, in addition to data from the airborne weather sensor. This, he said, makes for a flexible system that can handle almost any data-gathering or data-processing request. All Rights Reserved.

Quelling Cabin Noise in Turboprop Aircraft via Active Control

Cabin noise in turboprop aircraft causes passenger discomfort, airframe fatigue, and employee scheduling constraints due to OSHA standards for exposure to high levels of noise. The noise levels in the cabins of turboprop aircraft are typically 10 to 30 decibels louder than commercial jet noise levels. However, unlike jet noise the turboprop noise spectrum is dominated by a few low frequency tones.

Active structural acoustic control is a method in which the control inputs used to reduce interior noise are applied directly to a vibrating structural acoustic system. The control concept modeled in this work is the application of in-plane force inputs to piezoceramic patches bonded to the wall of a vibrating cylinder.

American Eagle is an American brand name for the regional branch of American Airlines , under which six individual regional airlines operate short- and medium-haul feeder flights. American Eagle’s largest hub is Charlotte Douglas International’s Concourse E, which operates over flights per day, making it the largest express flight operation in the world.

Prior to the Airline Deregulation Act in , most major US air carriers had maintained close relationships with independent regional carriers in order to feed passengers from smaller markets into the larger cities, and, in turn, onto the larger legacy carriers. In the post-regulation era, the hub-and-spoke system gained prominence, and in order to feed traffic from smaller markets into these newly established hubs, the major carriers outsourced regional operations to these smaller carriers.

These relationships included the use of code sharing , shared branding , and listing regional partners in the computer reservations systems of the mainline carrier.

Doomed plane was on autopilot, dropped feet in 5 seconds N. But federal aviation officials insisted Sunday that the planes are just as safe in winter weather as any other aircraft. The seat Q Bombardier aircraft “has an excellent record in icing conditions,” said Laura Brown, a spokeswoman for the Federal Aviation Administration. Continental Flight crashed into a home late Thursday, killing all 49 people aboard the plane and one man on the ground. It went down in light snow and mist just six miles from the Buffalo airport.

The crew had discussed significant ice buildup on their windshield and wings shortly before the crash, according to the NTSB. The crash has raised questions about the safety of small regional aircraft, which have grown in use since the terrorist attacks, when airlines found it economical to substitute smaller aircraft for some routes where they previously had used larger planes. Hall did not return a telephone message seeking comment left by The Associated Press.

Brown said the FAA had no reason so far to act. The flight was operated by Colgan Air of Manassas, Va. NTSB board member Steve Chealander said all planes must meet the same federal safety requirements before they are certified to fly. The answer is no,” he said Sunday. They all play by the same rules. Chealander said the airlines know it’s in their best interest to be safe.

Growing up we were not wealthy. My Dad was a refugee as a child and did his best providing for us.

The Federal Aviation Administration said today that a Brazilian-built turboprop of the type that crashed near Detroit in January was unusually vulnerable to icing and that the agency would require all planes of that model flying in the United States to be fitted with ice-detection equipment. Only last year the agency gave the Brazilian plane, the Embraer EMB, a clean bill of health, after extensive tests of its airworthiness under icy conditions. The tests were conducted after the ice-related crash of another kind of turboprop in Roselawn, Ind.

Then, this Jan. Documents on the Michigan crash that were released last week by the National Transportation Safety Board appeared to rule out propeller failure, which has been the cause of previous EMB crashes, and indicated that the plane had been flying too slowly to stay aloft — which can be a symptom of icing. When those tests were completed, the aviation agency ordered no changes for the EMB other than those it ordered for all turboprops: to require pilots to make visual checks for ice and to avoid flying in icy conditions when possible.
