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 ...
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
In aviation, a climb or ascent is the operation of increasing the altitude of an aircraft. It is also the logical phase of a typical flight (the climb phase or climbout) following takeoff and preceding the cruise. During the climb phase there is an increase in altitude to a predetermined level. [1] The opposite of a climb is a descent.
The Learjet 25 offers a high speed platform for business travel for six to eight passengers. Typical cruising altitudes are between Flight Level 390 and Flight Level 430 which means the Learjet 25 is capable of overflying most weather systems and congested airspace. A typical cruising speed is approximately Mach 0.76.
In a typical commercial passenger flight, the cabin altitude is programmed to rise gradually from the altitude of the airport of origin to a regulatory maximum of 8,000 ft (2,438 m). This cabin altitude is maintained while the aircraft is cruising at its maximum altitude and then reduced gradually during descent until the cabin pressure matches ...
The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2 + 1 ⁄ 2 times its size, to reduce its seat cost by 30%.
Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff . For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway .
