Missouri senator Claire McCaskill (Democrat) hit the nail on the head when she wrote to the FAA about easing rules on the use of portable electronic devices (PEDs) in aircraft. Her letter seeks to have the FAA reconsider restrictions on PEDs, citing as one example the fact that many airline pilots are now using switched-on iPads during taxi, takeoff and landing without any problems.
The supersonic business jet development program continues at Gulfstream Aerospace, but until the FAA decides to define “quiet” as it relates to the so-called sonic boom, “We just don’t see a business case,” said a spokesman.
In a series of patent filings last summer, Gulfstream emphasized mitigating the noise produced by the sonic boom, pointing out that regulations currently prohibit supersonic flight over populated areas.
Turboprop-engine manufacturers continue to develop technologies in anticipation of future demand for new or derivative regional airliners designed to carry approximately 90 passengers, a step up from contemporary aircraft offering around 70 seats. By January 1, Pratt & Whitney Canada hoped to have completed the first phase of a next-generation regional turboprop (NGRT) demonstration program intended to validate characteristics for a main centrifugal compressor. Meanwhile, U.S.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility near Paris, France. With 11,000 pounds of thrust, two of the units will power the Cessna Longitude super-midsize business jet.
Smyrna Air Center, a full-service FBO based at Smyrna/Rutherford County Airport near Nashville, Tenn., is showcasing its new GE H80 engine conversion option here at NBAA’12. While Smyrna (Booth No.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility, near Paris. With 11,000 pounds of thrust, the Silvercrest will power the Cessna Longitude super-midsize business jet. EASA engine certification is slated for 2015 and FAA validation is expected shortly thereafter.
A new turbulence-detection and -avoidance system now operating at Juneau International Airport (JNU) in Alaska is expected to be adapted for additional U.S. airports beginning with those most often affected by dangerously unstable air. Juneau often closes during bouts of significant turbulence to avoid risk to people, cargo and aircraft.
General Electric and Rolls-Royce tie for first place among turbofan manufacturers, each scoring an overall average of 8.0 for the quality of product support they provide their customers. Compared with last year, that score represented an improvement of 5 percent for GE and 1 percent for R-R.
The FAA issued an AD–Docket FAA-2012-0222– on September 6 for some versions of the Eurocopter AS350. The directive, which is effective from October 11 this year, was issued after an in-flight fire caused by the ignition of hydraulic fluid leaking from a damaged forward servo-control hydraulic hose. The AD is intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight.
The transonic speed spat between Cessna’s Citation Ten and Gulfstream’s G650 is likely to hit of the stops at Mach 0.95 when it encounters not “the sound barrier” but required safety margins. With the Ten’s top speed now pegged at Mach 0.935, Gulfstream’s G650 could thus leapfrog the Ten only slightly, if the Savannah-based aircraft manufacturer even chooses to do so.
