Today in Aviation History: Loss of USS Macon

Vintage Aviation News

Though the German Zeppelins were inflated with hydrogen, which was a more readily available and lighter lifting gas, it was flammable when mixed with oxygen, which doomed many a Zeppelin to a fiery end. While flying high over West Texas, the sun heated and expanded the helium lifting gas, forcing the Macon to rise up.

Turbulence

Air Facts

The eddies mixing with the vertical motion of the heat generating lift of the heated air makes for discomfort. The up motion of the lift vector from the surface temperatures, and the perpendicular wind vectors pushing the heated air along, make for a dynamism in space. As we turned back, the wind shear hit.

What Is a SPECI and When Is It Issued?

Pilot Institute

In aviation, staying ahead of the weather is a must. When weather conditions shift unexpectedly, that’s when a SPECI report comes in. A SPECI (or Special Report) offers a quick weather update between the routine METARs. Let’s explore how SPECIs are going to help you plan around unexpected weather twists.

Recognising NASA Technology on Modern Airliners

Fear of Landing

Airborne Wind Shear Detection During the 1980s and 1990s, NASA led a comprehensive research program to identify the characteristics of dangerous wind shear and validated technologies that can predict its severity while in flight.

Are Dry Microbursts Really An Invisible Trap? – Responding to Reactions

Chess In the Air

Most western pilots have patiently worked such lift for an hour or more while waiting for conditions to improve near their destination airport. I have tried to wait out a storm only to watch a bigger and badder one to move in and the overall weather situation getting worse. We need to watch out for all markers of high surface winds.

What Is an Outflow Boundary Shown on a Surface Analysis Chart? 

Flying Magazine

Answer: When looking at the surface analysis chart issued every three hours by meteorologists at the Weather Prediction Center (WPC), you may have seen a tan dashed line with a label “OUTFLOW BNDRY” nearby. Crescent-shaped convective outflow boundary as detected on NEXRAD Doppler weather radar.

Types of Thunderstorms in Aviation: From Simple to Severe

Pilot Institute

Weather experts classify storms as single-cell, multi-cell, squall line, or supercell. Thunderstorms create turbulence, wind shear, and icing risks for aircraft. Pilots should use weather forecasts and SIGMETs for safe flight planning. Lifting movement of moist air. What are Thunderstorms? What Are SIGMETs?
