18 maj 2023 · Use demonstrations, videos and other resources to take another look at air pressure from the perspective of how mobility is affected in pressurized NASA spacesuits. The Science Behind the Combo. A spacesuit must provide similar air pressure in the vacuum of space to that we experience on Earth.
Flight levels solve this problem by defining altitudes based on a standard air pressure at sea level. All aircraft operating on flight levels calibrate to this setting regardless of the actual sea level pressure.
3 maj 2023 · These multimedia files come from across the agency’s many missions in aeronautics, astrophysics, Earth science and human spaceflight. Users can download and use the content on their own sites. Search and download out-of-this-world images, videos and audio files.
25 sty 2024 · A flight level (FL) is a standard pressure altitude, expressed as three numbers. Aircraft flying on flight levels all measure their altitude from the same pressure setting, 1013.2 Hpa (or 29.92 InHg).
The flight levels correspond to the altitude in 100-ft increments (hectofeet) above the pressure surface of 1,013.25 hPa calculated according to the standard atmosphere. For example, FL050 is the pressure surface 5,000 ft above the pressure surface 1,013.25 hPa.
Flight Level (FL) A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals. Altitude above sea-level in 100 feet units measured according to a standard atmosphere.
