Which is faster 747 or 777?

Question: What is the fastest airliner and how fast does it fly? — submitted by reader James Kriplean, Knoxville, Tenn. Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach . … A 777 engine may be equal to two 747 engines, but the wing is not designed to take such a large engine in one place.

What is the slowest a 747 can fly?

A Boeing 747 under standard conditions must be going 296kph (184 mph) to take off. Additionally, weather factors can affect the ground speed need for takeoff. For example, a headwind will reduce the ground speed needed.

Can a 747 fly supersonic?

No. The Boeing 747 was not designed for supersonic flight, though during testing, it was pushed quite close to the sonic speed: Tom Cole, a spokesman at Boeing Commercial Airplane Co., said original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99.

What is the fastest jet in the world?

The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

How fast do planes go when landing?

Most commercial planes take off at roughly 160 to 180 MPH, while landings take place at approximately 150 to 165 MPH. As a general rule, airspeed is measured according to the velocity of the plane as it flies through the air.

How fast do planes go when taking off?

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

Why is supersonic flight banned?

In 1973 the U.S. outlawed civil supersonic flights over land for fear that sonic booms posed too great of a public nuisance. Today, technology has advanced to all but eliminate the “boom” from sonic booms. … This technology could in principle be deployed today, however the ban remains in place due to regulatory inertia.

Was Concorde faster than a fighter jet?

With superlative service and cuisine, exclusive airport lounges and stratospherically high airfares, Concorde passengers flew far above other flights, and cruised faster than fighter jets to their destinations.

What is the fastest passenger airplane ever built?

The fastest passenger aircraft in service today is the Boeing 747-8i, also known as the 747-8 Intercontinental. This model of the Queen of the Skies has a top speed of Mach 0.86.

Did the 747 break the sound barrier?

As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.

How high can a 747 go?

Every flight has its own ideal cruising altitude. This is the sweet spot where plane fly as fast as possible, but burn the least amount of fuel. A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft.
