Above Ground Level (AGL) A measurement of elevation, or "height", above a specific land mass (also see MSL). International Civil Aviation Organization The ICAO is the specialized agency of the United Nations with a mandate "to ensure the safe, efficient and orderly evolution of international civil aviation."

Civil IFR flights in class G airspace. [6] Canada: Uncontrolled IFR at or above 18,000 ft MSL. [7] ICAO countries: Code squawked when entering a secondary surveillance radar (SSR) area from a non-SSR area used as uncontrolled IFR flight squawk code. [1] EASA countries
In the United States and Canada, Victor airways are low-altitude airways. They are defined in straight-line segments, each of which is based on a straight line between either two VHF omnidirectional range (VOR) stations, or a VOR and a VOR intersection, [ 1 ] hence the beginning letter V (pronounced as Victor in the ICAO phonetic alphabet ).
Class A airspace is generally the airspace from 18,000 feet (~3.4 miles, 5.5 km) mean sea level (MSL) up to and including flight level (FL) 600 (~11.4 miles, 18.3 km), including the airspace overlying the waters within 12 nautical miles (NM) (~13.8 miles, 22.2 km) of the coast of the 48 contiguous states and Alaska. Unless otherwise authorized ...
In aviation, a control area (CTA) is "a controlled airspace extending upwards from a specified limit above the earth", not less than 200m (700 feet), although the limit does not need to be established uniformly within a control area. [1]

The training provides the skills needed to complete flights with less than the VFR minimum requirements. In the US, all pilots who fly above 18,000 feet above mean sea level (MSL) (a lower limit of Class A airspace) must have an instrument rating, [2] and must be on an IFR flight plan. This rating requires highly specialized training by a ...
