How fast is plane going before takeoff?

The speed at which planes take off can vary depending on the size and type of aircraft, as well as factors such as runway length, altitude, and weight. For commercial passenger jets, the takeoff speed typically ranges from around 130 to 180 miles per hour (or 210 to 290 kilometers per hour).



The speed at which a commercial aircraft travels before lifting off the ground, known as the liftoff speed (Vlof​), varies significantly based on the aircraft's weight, the ambient temperature, and the altitude of the airport. For a standard narrow-body jet like the Boeing 737 or Airbus A320, takeoff speeds typically range between 150 mph (240 km/h) and 180 mph (290 km/h). Larger, heavier aircraft like the Boeing 747 or Airbus A380 require higher speeds, often reaching 180 mph to 190 mph before the wings generate enough lift to overcome their massive weight. Pilots monitor three critical "V-speeds" during the roll: V1​ (the decision speed after which takeoff must continue), Vr​ (rotation speed, when the pilot pulls back on the yoke to lift the nose), and V2​ (the safe climb speed). In contrast, light private planes can take off at much lower speeds, around 60 mph to 100 mph, while historical supersonic jets like the Concorde required a staggering 250 mph (400 km/h) to get airborne.

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.

In a world where technology is continually advancing, one might expect airplanes to be faster than ever before. However, counterintuitively, modern passenger planes are actually flying at slower speeds compared to the aircraft of the past, even those from the 1960s and 1970s.

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). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

Do commercial planes fly at maximum speed? Large commercial jets fly from 550 to 580 miles per hour, but their landing and take-off speeds vary. Most commercial jets fly from 160 to 180 miles per hour, with landing speeds ranging from 150 to 165 miles per hour.

The higher a plane flies, the faster it can fly—to a point. “Less-dense air at higher altitudes means the actual speed the aircraft is traveling over the ground is much faster than the aircraft speed indicator shows the pilots in the cockpit,” says Kyrazis.

Aeroplanes are made to run on the runway before take off, so that they acquire the necessary lift.

Pilots can raise the spoilers to decelerate the airplane as it approaches the runway. And even while on the runway, pilots will typically leave the wing spoilers raised. Raised wing spoilers create drag, which essentially slows down the airplane so that it's able to brake more quickly.

As the plane descends into ground effect, it may actually accelerate if the engines are producing enough thrust, since in ground effect the plane requires much less power to keep flying. Power from the engines will translate into speed, if not height.

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.

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

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.

Can an airplane stay up in the air without moving forward just like helicopter? A: Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare.

In jet aircraft, an overspeed results when the axial compressor exceeds its maximal operating rotational speed. This often leads to the mechanical failure of turbine blades, flameout and total destruction of the engine.

Do pilots actually fly the planes? Pilots typically fly the plane during take off and landing. The pilot manually controls the plane until it reaches the required height.

The only thing a strong wind may do is affect the length of time the flight will take. If you have a strong headwind, it can slow down a flight. The opposite is true of a strong tailwind, and this may mean the flight takes longer than expected.

Fuel tanks of large planes, such the Airbus A380 and Boeing 747-800, can hold up to 140,000 and 216,000 liters of gasoline, respectively. These aircraft are able to nonstop flight for as much as 16 to 18 hours, achieving as much as 15,000 kilometers.

Scholars and experts in air transport generally assume the distance flown between airports is the shortest route (also known as the great-circle distance or the orthodromic route). However, in the real world, planes follow longer itineraries.

A lot of airports have restrictions on night flights because of noise issues. Also some smaller domestic airports close at night. There are a few that leave late at night in order to take advantage of the time difference in the arrival city. There aren't more because there isn't much demand for them.
