4 lis 2023 · Flight levels use standardized pressure to express altitudes above 18,000 feet. Only a handful of specialized aircraft can reach FL600 and above. Commercial airliners generally fly between FL250 and FL410. The transition between feet and flight levels occurs at 18,000 feet in the USA.
In aviation and aviation meteorology, a flight level ( FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
10 mar 2024 · Usually, FLs above 360 are reserved for long-haul flights or intercontinental flights(international). A320, Twin engine narrow body short-haul flight and not the very least wide-body jet engine aircrafts like A380, A350, B747, B777 etc., can fly at even higher altitudes like FL300 to FL460.
Flight Level is a standard altitude measurement system used in aviation. Unlike altitude, which is measured from the ground level, Flight Level is established based on a standard pressure reference, allowing for consistent altitude navigation regardless of atmospheric conditions.
Flight levels use QNE or pressure altitude, while altitude references QNH or local pressure adjusted to sea level pressure. Altitudes are used at low levels and flight levels at higher levels. The transition between altitudes and flight levels differs by country and is generally just above the highest obstacle in that country.
Strictly speaking a flight level is an indication of pressure, not of altitude. Only above the transition level (which depends on the local QNH but is typically 4000 feet above sea level) are flight levels used to indicate altitude; below the transition level feet are used.
