Flight Length Formula

The following two example problems outline the steps and information needed to calculate the Flight Length.

FL = FS * FT

• Where FL is the Flight Length (miles)
• FS is the flight speed (MPH) 
• FT is the flight time (hours) 

To calculate the flight length, multiply the flight speed by the flight time.

How to Calculate Flight Length?

The following example problems outline how to calculate Flight Length.

Example Problem #1:

1. First, determine the flight speed (MPH).
   • The flight speed (MPH) is given as: 400.
2. Next, determine the flight time (hours).
   • The flight time (hours) is provided as: 2.5.
3. Finally, calculate the Flight Length using the equation above: 

FL = 400 * 2.5

The values provided above are inserted into the equation below and computed.

FL = FS * FT = (miles)

Example Problem #2: 

For this problem, the variables required are provided below:

flight speed (MPH) = 500

flight time (hours) = 3

Test your knowledge using the equation and check your answer with the calculator..
