Why some engines fail in flight is the subject of a new NASA research program. “There is a question regarding the effect that moisture has on newer-technology engines.
A contingent of U.S. Air Force flight attendants participated in this year’s NBAA Flight Attendants/Flight Technicians conference, not just to learn from their peers but to share their own experiences using dry ice as a cooling medium to keep food safe on long trips. It turns out that a sufficient quantity of dry ice allows for weeks of operation and proper food storage. There are important safety considerations when using dry ice.
The FAA’s Draft Advisory Circular 20-147A released last month provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. Comments on the draft AC are due by November 1.
Eurocopter yesterday unveiled the X3 (“x cube”) demonstrator, a compound helicopter with a 220-knot cruise speed. The aircraft first flew on September 6 in hover, and is scheduled to fly again on Thursday. Some 100 flight-test hours are planned in the next 18 months, with the target speed expected to be reached in the first quarter.
The FAA yesterday issued Draft Advisory Circular 20-147A, which provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. The new guidance will replace AC20-147A, which was last revised in 2004. Comments on the draft AC are due by November 1 and can be sent to the FAA's John Fisher.
Proposed changes to Parts 25 and 33 address dangerous icing conditions caused by supercooled large drops including a requirement that manufacturers not only show that airplanes can operate safely in those conditions but also with specific performance and handling qualities and that “all new transport-category designs be able to fly in c
The FAA recently issued a revised Special Airworthiness Information Bulletin–SAIB SW-08-03R1–to warn helicopter operators of the “hazards of snow and ice,” according to the FAA Rotorcraft Directorate’s Safety Management Group in Fort Worth. The bulletin, “Recommendations for Rotorcraft During Icing Conditions,” was released in 2003, and new data has been added following additional FAA testing.
The FAA yesterday amended its certification standards for icing protection on transport-category airplanes. The new rule, which goes into effect September 2, will require new systems to increase pilot situational awareness during icing conditions.
As airports across the U.S. wage their annual struggle against winter weather, business aviation operators may soon find themselves familiar with a new de-icing method. Forced-air de-icers, which use high-volume, low-pressure air to help strip contamination from flying surfaces, have been used to augment the effect of glycol on airliners at major airports for years, but the business aircraft community has been slow to embrace them.
Pilots should “activate boots as soon as the airplane enters icing conditions,” according to a safety alert released in December by the NTSB. The alert (SA-014) is yet another attempt by the Board to persuade pilots that there is no such thing as ice bridging and that pilots should not wait for ice to build to one-quarter to one-half-inch thickness before inflating boots in icing conditions.
