Altitude Decompression Sickness: Tiny Bubbles, Big Troubles »

Most of us who fly unpressurized aircraft at altitudes of 18,000 feet and above don't have a full understanding of the significant medical risks involved and or precautionary measures we should take. The following lecture by two researchers at the FAA Civil Aeromedical Institute (CAMI) and transcribed by AVweb medical consultant Brent Blue is by far the best discussion of this subject we've seen. It is "must" reading for anyone who flies at the flight levels. More

The Controversy Over "Monovision" Lenses »

In October 1996 at New York's LaGuardia airport, a Delta MD-88 (Flight 554) clipped an approach light tower, slammed onto the runway and skidded nearly into Flushing Bay. The NTSB determined that the probable cause of the accident was the captains use of so-called "monovision" contact lenses which correct one eye for distance vision and the other eye for close-up vision. Dr. Brent Blue, a Senior AME and AVweb's chief aeromedical consultant, thinks the NTSB's conclusion is nonsense, as does Dr. Robert Liddell, past director of aviation medicine in Australia. Nevertheless, the FAA's official position is that pilots may not use "monovision" contacts. Dr. Bryan Angle expresses an opposing view that supports the NTSB findings, while opthalmologist/AME Neil Murray says the NTSB was on the wrong track. More
