How fast does a 747 have to go to lift off?


How fast does a 747 have to go to lift off? A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors. How Fast Do Airplanes Fly When Landing?


What speed do planes taxi at?

Safety. When taxiing, aircraft travel slowly. This ensures that they can be stopped quickly and do not risk wheel damage on larger aircraft if they accidentally turn off the paved surface. Taxi speeds are typically 16 to 19 kn (30 to 35 km/h; 18 to 22 mph).


How many hours can a 747 fly?

This depends on the size of the plane, its efficiency, and how fast it's flying. A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!


How fast do planes fly when landing?

While landing, speed is largely affected by the aircrafts current weight, commercial airplanes typically land between 130 and 160 mph (112 to 156 knots).


What is the fastest flight across the United States?

Today, the fastest time recorded for a West-to-East flight is an unbelievable 64 minutes, achieved in 1990 by the SR-71 Blackbird on its retirement flight to a museum in Virginia. This military aircraft was designed to outrun missiles, so was easily capable of the 2,124mph speed it averaged on its final flight!


Can a 747 break the speed of sound?

Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747-100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.


What speed does a 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 highest altitude a 747 can fly?

Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).


How fast is a 747 going when it lands?

At cruising altitude, most commercial airplanes fly at a speed of roughly 500 to 600 mph. When landing, however, they must reduce their speed. A typical 747, for instance, has a landing speed of about 160 to 170 mph. And upon touching the runway, airplanes must quickly brake until they come to a complete stop.


Can a plane fly at 60 000 feet?

Commercial jetliners have a limited elevation ceiling of about 45,000 feet. While corporate aircraft can fly higher, slightly above 50,000 feet, they are specifically designed for such purposes. However, reaching an altitude of 60,000 feet would require super-efficient engines and glider-like wings.


Why do planes speed up before landing?

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.
