A Qantas four-engined Boeing 747-400 at cruise altitude. Cruise is the phase of aircraft flight that starts when the aircraft levels off after a climb, until it begins to descend for landing. [1] Cruising usually comprises the majority of a flight, and may include small changes in heading (direction of flight), airspeed, and altitude.
Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres. 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 (30 m). In radio communications, FL290 ...
For private aircraft operating in the US, crew members are required to use oxygen masks if the cabin altitude (a representation of the air pressure, see below) stays above 12,500 ft (3,810 m) for more than 30 minutes, or if the cabin altitude reaches 14,000 ft (4,267 m) at any time. At altitudes above 15,000 ft (4,572 m), passengers are ...

In most [which?] areas, height is reported as a multiple of 100 feet (30 m), i.e. A025 is nominally 2,500 feet (760 m). When cruising at higher altitudes aircraft adopt flight levels (FLs). Flight levels are altitudes corrected and calibrated against the International Standard Atmosphere (ISA). These are expressed as a three-figure group e.g ...

This is important for clearing an obstacle, and therefore is the speed a pilot uses when executing a "short field" takeoff. V X increases with altitude, and V Y decreases with altitude until they converge at the airplane's absolute ceiling. Best angle of climb (BAOC) airspeed for an airplane is the speed at which the maximum excess thrust is
