Density altitude (DA) reduces aircraft performance; it's pressure altitude adjusted for temperature and humidity, and even one of these factors can significantly impact performance. High DA increases ...

Despite what extraordinarily overpowered quadcopters suggest, the air pressure of whatever a flying machine flys at is extremely important. Pressure is dependent on altitude and temperature, and there ...

Altitude and barometric pressure are closely related. As altitude increases, barometric pressure decreases, or stated another way, barometric pressure is inversely proportional to altitude. This is ...

The Colorado mission flights took place from an airfield situated at 5,800 feet above sea level, with temperatures reaching 36°C (96.8°F) and a takeoff density altitude of 9,500ft. The B23 Energic ...

Sniper’s Hide is talking about a new modular data book from Impact Data Books Inc., developed in conjunction with Adaptive Consulting and Training Services. They’re stated goal is to “….bring military ...

David asks: Hey Ray, why is it when it gets too hot, airplanes cannot fly? This is a great question because it can actually become too hot for some aircraft to fly. Thinking of hot air balloons, that ...
