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 ...

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 ...

American Airlines grounded 45 regional flights at Sky Harbor Airport in Phoenix Tuesday as temperatures soared near 120 degrees. A veteran pilot in Dallas agreed to explain why a simple math problem ...

The combination of “hot and high” always has been a detriment to aircraft performance and safety. With excessively hot temperatures this summer, aircraft operators will have to take measures to reduce ...
