Understanding Cruise Speed

Airbus A319 Jet Charter



  • Top speed vs. cruise speed: Top speed is the fastest, but least fuel-efficient option. Cruise speed, reached after climbing, balances speed and efficiency.
  • Cruise speed examples: Boeing 747 cruises at 490 nautical miles per hour, while the Cessna Citation X is a “speed king” at 604 mph.
  • Factors affecting cruise speed: Various factors like temperature, wind, and altitude can impact a plane’s cruising speed.

While spending time in the sky on a private jet charter, you may find yourself wondering what it takes to keep the jet in the air. What does it take to reach maximum heights and settle at an efficient cruise speed?

Velocity, power, and consumption all play a key role in determining how fast a private jet can go. They also determine how quickly it can get to cruising speed.

Let’s take a closer look at what maximum cruise speed looks like. We’ll cover how planes reach their maximum performance and how Stratos calculates average airplane cruising speeds.

Maximum Speed vs. Cruise Speed

On average, an aircraft typically flies at 85% of its top speed when it reaches its cruise speed. Max cruise speed would be 100% of its top speed. This is when the most fuel consumption occurs.

Cruise speed, on the other hand, is the average speed an aircraft reaches once the aircraft is no longer climbing.

Cruising speed meaning can be compared to using cruise control on your car. Once you reach a desired highway speed, activating cruise control maintains that speed without needing constant acceleration.

Similarly, an aircraft reaches its cruising speed after its initial climb, offering a consistent and efficient travel pace. This can also be referred to as the cruise velocity. In many ways, this may be considered the most efficient positioning of the plane. The amount of fuel and effort it takes to climb is far less efficient than a plane at cruising altitude.

What Is the Difference Between Top Speed and Cruising Speed?

Top speed is the fastest speed an aircraft can reach. This isn’t usually maintained as it isn’t very fuel efficient and it can cause undue wear and tear on an aircraft. Cruising speed is the average speed an aircraft flies at once it’s finished its ascent.

At top speed, the pilot cannot maintain the velocity of the aircraft. At cruising speed, there’s a more sustained travel experience, making for better fuel, speed, and travel efficiency.

Reaching Peak Performance

Commercial and passenger aircraft are designed for peak performance at their cruise speed. However, some factors can affect the performance desired while maintaining average jet speed.

Some of these factors include:

  • Payload (the weight of passengers, crew, and cargo)
  • Center of gravity
  • Humidity
  • Speed
  • Temperature

Understanding the Cruise Speed of Common Aircraft

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 747 cruising speed is 490 nautical miles or Mach 0.85.

In comparison, a Cessna Citation X boasts a cruising speed of 604 mph. This typical private jet is the undisputed king of speed. Because of its ability to fly so quickly, it can make the flight from New York to Los Angeles in less than four hours.

Calculating Airplane Cruise Speed

The average plane cruise speed can be found in the specs or performance charts. When determining this speed several factors are involved, including:

  • Atmosphere temperature
  • Wind direction and speed
  • Altitude
  • The aircraft’s performance
  • The speed of sound
  • And more

And when you look at the relative velocity of the wind and apply it against the in-flight cruising speed, you can determine the ground speed of an aircraft.
