In aviation and aviation meteorology, a flight level (FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
FL180 and FL300 stand for Flight Level 180 and Fight Level 300. Flight levels are spaced 100ft apart on an altimeter that is set to the standard sea level pressure (QNE) of 1013.25 hectopascals or 29.92 inches of Mercury. So indeed, FL300 means 30,000 ft.
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). This is based on the principle of something called the International Standard Atmosphere.
A Flight Level (FL) is the vertical distance of an aircraft above the ISOBARIC SURFACE of 1013.25hPa (hecto Pascal) or 29.92 in Hg (inches of Mercury). An ISOBARIC SURFACE is the invisible landscape that connects all points with the same atmospheric pressure.
Flight Level specifically refers to Pressure Altitude in 100 foot increments within the Standard Pressure Region, which in North America starts at 18000 ft and above, and at various lower altitudes elsewhere.
10 mar 2024 · Flight Levels (FL): Here’s the definition of a Flight Level by the ICAO (International Civil Aviation Organization): “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.”.
AGL – (Above Ground Level) – The vertical distance measured between the aircraft and a specific land mass. Aileron – The movable, hinged flight control surfaces that are used in pairs with opposite motions to control the roll of an aircraft. Learn more about the parts of an airplane.
