Your Margin of Safety? »

When was it, to avoid compromising personal limits, you decided not to fly? Sure, serious deteriorating weather conditions are an obvious one. As I write this, severe turbulence SIGMETS from surface to 5000 feet have been issued over northwest Europe, which for me is an obvious "no flight." But there are some diehards (or dare devils) out there, who are willing to give it a try anyhow. More

Dissecting The PIO »

We see it happen here all too often. The Franklin County Airport in Sewanee, Tenn., sits at the western edge of the Cumberland Plateau. During cooler months, northwest winds are thrust up the side of the plateau and swirl back down toward the airport. Tall trees surround the runway and make the airport difficult to see throughout the approach. Pilots in the pattern are greeted by updrafts followed by downdrafts that can make landing on our 50-by-3700-foot runway a challenge. More

Transatlantic Homebuilt »

Flying an RV-8 from Los Angeles, California to Oxfordshire, England in 19 days may strike many as an adventure of a lifetime. For me, the 7000 NM trip was my way to return home after working four years in the Tesla Motors Design Studio in Hawthorne, California. Airfields along the Crimson Route, partially developed in WW-II as a way from North America across Greenland and Iceland to Britain and the European theater, would provide the critical fuel stops to complete my journey.

Serious IFR: Flying the Hump »

As humble seekers of aeronautical knowledge it might do us well to tread among the giants of an earlier generation and listen to what sort of instrument flying they did, and decide if we, in our modern machines, are accomplished pilots. More

Pitot-Static Systems »

No matter how much automation we fly behind, no matter how many air-data computers are installed and no matter how simple it is, it's likely a pitot-static system—pretty much like the one Lindbergh flew across the Atlantic—is what generates airspeed and some other basic flight information aboard the aircraft we fly. These systems are relatively simple, consisting of basic sensors, some plumbing and sensitive instrumentation. The difference in air pressure does all the work. More
