The FAA has extended the duration of third-class medicals from 36 calendar months to 60 calendar months (five years) and first-class medicals from six calendar months to 12 calendar months for pilots under age 40. According to AOPA, current and expired medical certificates are grandfathered under this rule. The second-class medical duration remains at 12 calendar months, regardless of pilot age.
Fortunately, it was a clear, sunny day (rather than the proverbial dark, stormy night) over the Northeast when the electrical power gridwork gave up the ghost at 4:11 p.m. on August 14. Though 9/11 jitters surfaced, initial fears of terrorism were quickly calmed. U.S. and Canadian power providers were pointing fingers at each other long before most affected areas had their lights back on.
Flight Safety Technologies of Mystic, Conn., is developing two hazardous warning systems–Socrates and Unicorn. Its Socrates wake-vortex detection and tracking technology is slated to be tested for a month at Denver International Airport starting August 15. Unicorn is a collision avoidance system designed particularly to prevent midairs between piloted airplanes and government-operated unmanned aerial vehicles.
Until about a year ago, infrared enhanced vision systems (EVS) were exclusively the bailiwick of operators of large aircraft, in which they were installed as upgrades to the standard head-up display. Primarily, the aircraft were the Gulfstream IV/IV-SP/G300/G400, GV/ G500/G550 and Bombardier Global Express, and their EVS add-ons– built by Kollsman of Merrimack, N.Y.
Aviation has an image problem in this age of climate change as a major contributor of CO2, even if the reality is that as a CO2 producer the segment is responsible for just 3 percent of greenhouse gases (GHGs) globally.
The FAA issued a final rule that specifies the extended duration of first- and third-class medicals for pilots under age 40. Effective July 24, the agency extended the duration of third-class medicals from 36 calendar months to 60 calendar months and first-class medicals from six calendar months to 12 calendar months for pilots under age 40. According to AOPA, current and expired medical certificates are grandfathered under this rule.
Doncasters is investing close to $350,000 to develop the plasma spray facility at Doncasters Airmotive and Doncasters Aerospace Components in Shrewsbury, UK. Plasma spray technology is used to apply various metallic and ceramic coatings onto components by feeding the metallic or ceramic powder into a plasma flame with intense heat that melts the powder and sprays it onto the component.
Congress has allocated $8.5 million to research on alternative piston aviation fuels in the coming fiscal year. Though current supplies and production of 100LL avgas are secure for the near term, AOPA argues that alternatives may become necessary later.
There were many times during my years as a mechanic when I was working totally exhausted, but for a number of reasons I continued past the point that I was in danger of causing damage to an aircraft or to myself. For years many of my coworkers and I believed that we were OK to work and not impaired by a lack of rest.
Ongoing research into new composite materials is expected to yield major enhancements in performance, weight and cost for the aerospace industry in the coming years. New ways of laying up carbon fiber, such as weaving, are already enabling more complex shapes. Thermoplastic resins are making manufacturing easier, and the practice of integrating several functions into one part is reducing part counts.
