Quick Answer: How fast can a commercial jet fly?

A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.

What is the average speed of a commercial jet?

  • A commercial jetliner usually takes off between 160 and 180 mph. The varying speed can be due to wind resistance, overall weight capacity and/or the use of high-lift devices.

How fast does a 747 fly?

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.

What is the maximum speed of commercial airplane?

The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph).

What is the fastest commercial jet?

Boeing 747-8i

And according to Boeing, the 747-8I is the world’s fastest commercial jet. This plane can reach an impressive speed of Mach 0.86; it is currently in service with several major commercial airlines such as Air China, Korean Air and Lufthansa.

Has a 747 ever broken 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.

What speed do planes land at?

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.

Do planes dump poop?

In a plane toilet, strong suction and teflon-like walls pull excreta away using a small quantity of water. As you press the flush button, the vacuum at the bottom of the bowl sucks the waste into a holding tank. The waste is sucked into a tanker at the airport and then dumped.

Why do aircraft fly at 35000 feet?

The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.

What is the slowest speed an airplane can fly?

Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).

Do airplanes have a speed limit?

According to FAR 91.117(a), unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 mph). If you’re flying a piston aircraft, this might not mean a lot to you.

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 fastest plane in 2020?

Among them, we will list out the top 10 fastest planes in the world:

  • Sukhoi Su-27. Top Speed: 2,500 km/h.
  • General Dynamics F-111 Aardvark. Top Speed: 2,655 km/h.
  • McDonnell Douglas F-15 Eagle. Top Speed: 3,017 km/h.
  • Mikoyan MiG-31. Top Speed: 3,000 km/h.
  • North American XB-70 Valkyrie.
  • Bell X-2.
  • Mikoyan MiG-25.
  • Lockheed YF-12.

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.

What is the most fastest plane 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.
