What does cruise mean for aircraft?
Cruise is a flight phase that occurs when the aircraft levels after a climb to a set altitude and before it begins to descend. Cruising usually consumes the majority of a flight, and it may include changes in heading (direction of flight) at a constant airspeed and altitude.
What is cruising airspeed?
Definition of cruising speed : the speed at which an airplane, a boat, etc., usually moves when it is traveling at a fast speed for a long distance The boat has a cruising speed of 25 knots.
What is meant by cruising level?
A level maintained during a significant portion of a flight. See also altitude.
What is cruising altitude for a plane?
Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.
Is cruise speed ground speed?
While the weight decreases due to fuel burned, the change is very small relative to the total aircraft weight. The aircraft maintains a constant airspeed called the cruise velocity. The ground speed is equal to the airspeed plus the wind speed using vector addition. The motion of the aircraft is a pure translation.
What is cruising speed of a 747?
The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant.
What is cruising speed of a 737?
The advanced wing airfoil design provides an economical cruise speed of . 78 Mach (590 mph). The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet (12.5 km), compared to 37,000 feet (11.3 km) for the 737-300/- 400/-500 models, and 39,000 feet (11.9 km) for the competition.
When does a cruise occur in a flight?
Cruise is a flight phase that occurs when the aircraft levels after a climb to a set altitude and before it begins to descend. Cruising usually consumes the majority of a flight, and it may include changes in heading (direction of flight) at a constant airspeed and altitude .
What does the word cruise mean in English?

Familiarity information: CRUISE used as a noun is very rare. • CRUISE (verb) The verb CRUISE has 4 senses: 1. drive around aimlessly but ostentatiously and at leisure. 2. travel at a moderate speed.
What is the definition of a cruise climb?
CRUISE CLIMB- A climb technique employed by aircraft, usually at a constant power setting, resulting in an increase of altitude as the aircraft weight decreases. (See CRUISING ALTITUDE.) We see that the power curve is rather flat on top.
What’s the average cruise speed of an airplane?
Cruise speed. This altitude is usually where the higher ground speeds, the increase in aerodynamic drag power, and the decrease in engine thrust and efficiency at higher altitudes are balanced. The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 475–500 knots (880–926 km/h; 547–575 mph ).
