Instead, the lowest usable "'flight level'" is the transition level plus 500 ft. However, in some countries, such as Norway for example, [ 9 ] the transition level is determined by adding a buffer of minimum 1,000 ft (300 m) (depending on QNH) to the transition altitude.

It is the setting that causes an altimeter to read the aircraft's flight level (FL). Flight levels are given in hundreds of feet (for example: FL100 = 10 000 ft). Atmospheric pressure changes over time and position. Thus, the flight level is not "straight", because it has a different altitude (elevation above the mean sea level).
The required altitude depends on the type of terrain, such as low vegetation or low buildings, tree canopy layer of less than 45 m (148 ft), presence of tall buildings or concrete pylons with heights of up to 25 m (82 ft) international standard, or emergent tree layer canopy and lattice steel electricity pylons to 100 m (330 ft) being present ...
NATO tactical ultra-low-level flight training in Canada is located at CFB Goose Bay in Labrador.In response to lessons learned from the Vietnam War and the growing sophistication of Soviet anti-aircraft radar and surface-to-air missile technology being deployed in Europe, NATO allies began looking at new doctrines in the 1970s–1980s which mandated low-level flight to evade detection.
Flight levels are usually designated in writing as FLxxx, where xxx is a two or three-digit number indicating the pressure altitude in units of 100 feet. In radio communications, FL290 (29,000 ft; 8,850 m) would be pronounced as "flight level two nine(r) zero."
Right now the first-round sites will be on campuses — No. 9 Tennessee at No. 8 Ohio State, No. 10 Indiana at No. 7 Notre Dame, No. 11 SMU at No. 6 Penn State and No. 12 Clemson at No. 5 Texas.
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 ).
