In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres . The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg .
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
Maximum elevation figure (MEF) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area. It is of interest to pilots, who want to be aware of the highest mountain peaks and tall towers nearby, so that they can fly above them to avoid controlled flight into ...
When the pressure at sea level is by chance the international standard then the flight level is also the altitude. To avoid confusion, below the transition altitude, height is referred to as a numeric altitude, for example 'descend 5000 feet' and above the transition altitude, 'climb flight level 250'.
The division between low altitude and high altitude is usually defined as the altitude that marks transition to flight levels (in the United States, this is taken to be 18,000 feet MSL by convention). Historically, they were called air navigation maps, airway maps, and flight charts. [3] [failed verification] [4] [failed verification]
Transition level - flight level 65. Aircraft above Flight Level 65 (6500ft) should set their altimeters to QNH 1013. When descending below, they should set their altimeter to the local QNH given later in the ATIS. Expect an ILS approach. Expect the approach procedure to be the one published for Runway 22 ILS. Surface wind 250, 14 knots.
In the 1940s (original ICAO regulations), standard separation was 1000 feet except in specific circumstances, when it was 500 feet. [2] In 1958 the standard vertical separation of aircraft in controlled airspace was set at 1,000 feet from ground level or sea level to flight level 290, and at 2,000 feet above flight level 290. [3]
North Atlantic Tracks for the westbound crossing of February 24, 2017, with the new reduced lateral separation minima (RLAT) Tracks shown in blue. The North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), are a structured set of transatlantic flight routes that stretch from eastern North America to western Europe across the Atlantic Ocean, within the ...
