What speed does 747 cruise at?


What speed does 747 cruise at? On average, the typical cruising speed of a large commercial aircraft, like a Boeing 747, is somewhere between 475 and 500 knots (roughly 575 mph). So what is the cruising speed of a 747? Depending on passenger load, the average cruise speed of a 747 is 490 nautical miles or Mach 0.85.


What is the fastest commercial plane still in use?

The 747 is one of the largest commercial aircraft ever built, and the 747-8 Intercontinental (747-8i) variant wins the race as the fastest commercial plane in service today. This plane is as tall as a six-story building with a top speed of Mach 0.86. That's equivalent to 659.85 mph.


How many airplanes are in the sky at one time?

At any given time, there are between 8,000 and 13,000 airplanes in the air. Over 30,000 flights with two million passengers on board take off every single day in the United States alone.


Why is the 747 no longer popular?

Built in 1967 to produce the mammoth jet, it remains the world's largest manufacturing plant according to Boeing. But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes.


Why does 747 fly so fast?

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. The sweep also reduces the wingspan, allowing the 747 to use existing hangars.


What is the fuel capacity of a 747?

Let's start with a look at the most famous of jets, the Boeing 747. The Boeing website states that this model, with a gas tank capacity of 63,500 gallons, may burn five gallons of jet fuel per mile of flight.


How fast is a 747 going when it takes off?

What speed does a Boeing 747 take off at? A fully loaded Boeing 747 'Jumbo Jet' on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph. The calculated take-off speeds vary depending on environmental conditions, runway length and weight.


Why does 747 have a hump?

Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.


Do private jets fly faster than commercial?

Private aircraft can travel faster than commercial airliners. Part of this has to do with the weight of the jet itself. Private jets weigh less than large commercial aircraft, allowing them to ascend and descend faster than commercial jet.


What is the fastest plane in the world?

The North American X-15 may be the fastest plane in the world, with speeds at 4,520 mph and Mach 5.93. It's an experimental aircraft used and powered by NASA and USAF.


Why do pilots love 747?

Many long-haul planes have pilot bunks. On some airplanes you have to pass through the passenger cabin to reach the bunks or lavatories; on others, like the 747, you need never leave the cockpit area and can move freely between the bunk and the bathroom in your pajamas.


What is the fastest plane a civilian can fly?

Speed is often measured in kilometers per hour, but also in Mach, which corresponds to the speed of sound. For reference, Mach 1 is approximately 1,230 km/h. The Blackbird, an American military aircraft, holds the title of the fastest aircraft in the world with a top speed of Mach 3.32, or 3,540 km/h.


What is the fastest a 747 has ever flown?

Aided by a more powerful jet stream than usual, this rapid journey saw the 747 reach a top speed of 825 mph. Photo: Markus Mainka I Shutterstock. Popular Mechanics reports that the reason for it being so powerful on this occasion was a 'bomb cyclone' near Greenland.


What is the lifespan of a 747?

A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.
