Enter the horizontal and vertical velocities into the calculator to determine the cruise velocity.

Cruise Velocity Formula

The following equation is used to calculate the Cruise Velocity.

Vc = Vy + (Vy-Vx)
  • Where Vc is the cruise velocity (m/s)
  • Vy is the vertical velocity (m/s)
  • Vx is the horizontal velocity (m/s)

To calculate the cruise velocity, add the vertical velocity to the difference between the vertical and horizontal velocity.

What is a Cruise Velocity?


A cruise velocity describes the speed at which an aircraft travels while cruising.

How to Calculate Cruise Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Cruise Velocity.

First, determine the vertical velocity. In this example, the vertical velocity is found to be 100 m/s .

Next, determine the horizontal velocity. For this problem, the horizontal velocity is found to be 75 m/s.

Finally, calculate the Cruise Velocity using the formula above:

Vc = Vy + (Vy-Vx)

Vc = 100 + (100-75)

Vc = 125 m/s
