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 ...

Airplane takeoff speed (rotation speed) varies greatly depending on numerous factors, including aircraft weight, wing design, weather conditions (wind, temperature, density altitude), and aircraft ...

The achievement is "one of those unforgettable peaks that define great human and technological adventures," the SolarStratos mission said in a statement.

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 ...

The Federal Aviation Administration has ordered airlines to test cabin altitude pressure switches in all Boeing 737s, saying some operators have reported that both switches on several aircraft had ...
