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.
Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft. 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.
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
The flight from New York JFK departs around 11:30 p.m. daily and arrives two days later around 6 a.m. (meaning, my flight departed on the night of March 11 and arrived in Singapore on the morning ...
The 747-500X concept featured a fuselage length increased by 18 feet (5.5 m) to 250 feet (76 m), and the aircraft was to carry 462 passengers over a range up to 8,700 nautical miles (16,100 km; 10,000 mi), with a gross weight of over 1.0 Mlb (450 tonnes). [242]
