How Fast Does a 747 Cruise At?

By Robert Palmer

Have you ever looked up at the sky and wondered how fast a Boeing 747 flies? The answer is not as straightforward as you might think. The cruising speed of a 747 can vary depending on a variety of factors, including altitude, weight, and weather conditions.

What is a Boeing 747?

Before we delve into the cruising speed of a 747, let’s first take a closer look at this iconic aircraft. The Boeing 747, also known as the “jumbo jet,” was first introduced in 1970 and quickly became one of the most popular commercial airplanes in the world. With its distinctive hump on the front section of the aircraft, the 747 has been used for both passenger and cargo transport.

How Fast Can a 747 Fly?

The cruising speed of a Boeing 747 is typically around 570 mph (920 km/h), although it can vary depending on factors such as altitude and weather conditions. At maximum cruising altitude – around 35,000 feet – the typical cruising speed for a 747 is Mach 0.85, which translates to around 567 mph (912 km/h).

Factors Affecting Cruising Speed

As mentioned earlier, several factors can affect the cruising speed of a Boeing 747. One such factor is altitude – at higher altitudes where there is less air resistance, planes can fly faster. Weather conditions can also play a role – headwinds can slow down an airplane’s speed while tailwinds can increase it.

Another factor that affects cruising speed is weight. A fully loaded plane will typically fly slower than one that is only partially loaded because it requires more power to maintain lift.

Interesting Facts About the Boeing 747

  • The first Boeing 747 was flown commercially by Pan American World Airways on January 22, 1970.
  • The 747 has a wingspan of around 211 feet (64 meters) and can carry up to 660 passengers.
  • The maximum range for a 747 is around 8,000 nautical miles (14,800 km).

Conclusion

The cruising speed of a Boeing 747 is typically around 570 mph (920 km/h), but this can vary depending on various factors. Despite being introduced over 50 years ago, the Boeing 747 remains an iconic aircraft and continues to be used for both passenger and cargo transport.
