Stayin' Alive with Pulse Oximeters

Last month we talked about the dangers of hypoxia and some procedures to avoid the potentially fatal effects of low blood oxygen levels. Symptoms of hypoxia vary from airman to airman so it is a good idea to take a ride in a hyperbaric chamber to...


Up Where the Air is Thin: Hypoxia

Oxygen is the elixir of life. Our body’s cells need it to metabolize. Without enough of it we die. It just so happens that as we ascend in the atmosphere that’s exactly what happens—we get less and less of this vital gas and we suffer from low...


Flying With Contact Lenses

Every time you fill out your MedXpress form for a flight physical, you’ll find Question 17b. “Do You Ever Use Near Vision Contact Lenses While Flying?” Most folks get the question wrong. It’s not surprising since if you are not an eye doctor,...


You Can Fly With Insulin-Dependent Diabetes

There was a time when the diagnosis of diabetes was the prelude to a short life. Then insulin came along in 1922, which gave diabetic patients a reprieve from the immediate effects of a deficiency of that vital hormone. However, as time passed it...


Say Again, Please: Flying and Hearing

If you don’t think hearing is important, try flying IFR into Chicago Bravo Airspace some afternoon. We were slated to land at Midway taking the OHHMY transition on the ENDEE SIX ARRIVAL. I dutifully plugged in all that info into my trusty Garmin...

COVID-19 is storming back with the Delta variant. Yet another deadly epidemic lurks in the background, claiming many lives—opioid abuse. According to government estimates almost one-third of the population suffers from chronic pain of one source...


Deydration And Heat Stroke: No Fun In The Sun

Over the past few years, we’ve been setting record temperatures and dealing with the health hazards that go with them. Very few of our general aviation fleet has the luxury of air conditioning. Even if you do, summer flying without adequate fluid i...


Oh Say Can You See: Flying with Color Blindness

If you have ever landed at a Class Bravo airport, you know that the runway looks like the Las Vegas Strip. The strobing glide path, PAPI, illuminated runway centerline, side and center line taxi way markers all combine to make a colorful and...

More than 1.2 million Americans live with the loss or absence of a limb. Each year over 1,000 children are born with limb deficiencies. Over 130,000 amputations are performed annually as a result of trauma or disease, with 86 % of these amputations... Full story


Death by Diphenhydramine: The Benadryl Bane

Breast Cancer and Medical Certification

Breast cancer is common. Currently, the average risk for a woman in the United States to develop breast cancer sometime in her life is about 13%. That’s about a 1 in 8 chance. Fortunately, if it is detected early the outlook is good. That’s the...


Aviation Fluids: Put Them in the Plane Not You

To get an airplane off the runway you’ve got to pump a lot of unusual fluids into her…avgas, oil, hydraulic fluid, deicing solvent. And let’s not forget the coffee and pop to pump into the pilot! There are many liquids involved in flying and...


COVID-19 Vaccines: Get 'em Before They're Hot!

t is my sincere hope that the day is near when I will not be devoting this column exclusively to Corona Virus Disease 2019 (COVID-19). However, more Americans are dead from COVID-19 than died in the entirety of World War II. Pilots are in a unique...


Seat Belts and Shoulder Harnesses: Use 'em!

The NHTSA isn't the only federal agency that has fun crashing things! Our own FAA's Civil Aerospace Medical Institute (CAMI) in Oklahoma City has blasted a number of perfectly good airplanes to smithe...

One thing about the aviation community, we get around. We are exposed to many different terrains, population, cultures and, unfortunately infections. If you’re flying under Part 121 or 135 you often cover a lot of territory and come into contact... Full story
