The study's results come as the Federal Aviation Administration (FAA) considers a proposal to raise the mandatory age of retirement for commercial airline pilots to 65 from the current age of 60.
For the study, researchers tested 118 non-commercial airline pilots, age 40 to 69, annually for three years. All pilots were currently flying, had between 300 and 15,000 hours of total flight time, and had a FAA medical certificate. Pilots were tested on accuracy of executing communications, traffic avoidance, scanning cockpit instruments to detect emergencies, and executing a visual approach landing.
The study found while older pilots initially performed worse than younger pilots, older pilots showed less of a decline in overall flight summary scores than younger pilots, and over time their traffic avoidance performances improved more than that of younger pilots. The study also found pilots with advanced FAA pilot ratings and certifications showed less performance decline over time, regardless of age.
"These findings show the advantageous effect of prior experience and specialized expertise on older adults' skilled cognitive performances," said study author Joy L. Taylor, PhD, with the Stanford/VA Aging Clinical Research Center in Palo Alto, California. "Our discovery has broader implications beyond aviation to the general issue of aging in the workplace and the objective assessment of competency in older workers."
Researchers suggest that pilots with advanced FAA pilot ratings may maintain performance over time due to a mechanism of preserved task-specific knowledge, known as crystallized intelligence, which is similar to what is seen in music or expert chess playing.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
