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.
The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...
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.
Normal cruise altitudes range from 41,000 to 47,000 feet (12,500-14,900 m) and the aircraft's maximum cruise altitude of 51,000 feet (15,500 m) is a distinction shared by only a handful of civil aircraft.
The aircraft is pressurized and was designed for a 6.5 psi (45 kPa) differential pressure, giving an 8,000 ft (2,438 m) cabin pressure at its maximum altitude of 28,000 ft (8,534 m). [ 8 ] The turbine version of the Evolution is powered by the 750 hp (559 kW) Pratt & Whitney PT6A-135A and has a maximum cruise of 300 kn (556 km/h) at 25,000 ft ...
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 ...
