Know the signs of hypoxia

It only takes a few seconds for the heads-up — if you know what you’re feeling. And in an airplane, those few seconds spell the difference between getting back safely — or not.

We’re talking decompression — one of the things the flight attendants or video tell you about when they’re demonstrating the deployment and use of those bright yellow oxygen masks.

“It can happen real fast,” said Dr. Warren Jensen (pictured above), a flight surgeon and Chester Fritz Distinguished Professor of Aviation in the John D. Odegard School of Aerospace Sciences. Jensen also runs the school’s altitude chamber, where students learn how to deal with decompression and hypoxia, a condition that occurs when the body is deprived of oxygen, such as when an airplane loses cabin pressure.

In a visit to Grand Forks, N.D, just ahead of election day, Sen. John McCain (R-Ariz.) got a good look at a spot for a mall — an unmanned aircraft systems (UAS) mall.

A key spot on the tour was the University of North Dakota’s UAS facilities. UND would be a key tenant of the mall.

It looks easy to fly unmanned aircraft: Launch, fly, land. But there’s lots more to keeping an Unmanned Aircraft System (UAS) safely aloft than toggling controls from the ground.

“Among the major technical challenges facing the UAS industry is the sense-and-avoid system aboard the aircraft,” said Naima Kaabouch, associate professor of electrical engineering at the University of North Dakota College of Engineering and Mines and an expert in sense-and-avoid electronics and software.

Unmanned Aircraft Systems and the GA pilot

Unmanned aircraft systems — UAS — are now in the public lexicon.

Everybody’s heard of UAS, but not everyone knows what they’re all about. That state of affairs underpins some widespread misconceptions about what UAS are, who uses them, and how they’ll affect the National Airspace.
