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 ...

Proper preflight planning is crucial for short and soft field takeoffs, accounting for weight, balance, weather, and runway conditions (surface and length). Technique varies depending on the type of ...

Is there a plug and chug way to do it if I know my barometric pressure, temp, and altitude? I need to get it everyday before I have a flying lesson. I hate using that round slide-rule flight computer ...

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 ...

Question: Do airplanes have a hard time taking off in Arizona because of the hot weather? — Submitted by reader Chris Batten, Lilburn, Ga. Answer: I would not say they have a hard time, but ...

Swiss pilot Raphael Domjan beat the altitude record for a solar-powered electric plane in a flight that took him soaring to 9,521 meters, or 31,237 feet, his team announced Wednesday. The SolarStratos ...

In a study performed on Mestizo and Quechua Indian cadavera from the coast and highlands of Peru we found that Peruvian male cadavers had bone ash and protein segment densities similar to U. S. whites ...
