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 ...

MOLINE, Ill. — If you've ever climbed a mountain or taken a ride in an airplane, you know that pressure changes with height. Hikers that work in extreme altitudes have to use techniques to keep up ...
