## Takeoff Distance Formula

The following formula is used to calculate the Takeoff Distance.

**TD = GR + D50**

- Where TD is the Takeoff Distance (FT)
- gr is the ground run (ft)
- D50 is the distance to reach 50 vertical feet (ft)

## How to Calculate Takeoff Distance?

The following example problems outline how to calculate Takeoff Distance.

Example Problem #1:

- First, determine the ground run (ft).
- The ground run (ft) is given as: 1000.

- Next, determine the distance to reach 50 vertical feet (ft).
- The distance to reach 50 vertical feet (ft) is provided as: 70.

- Finally, calculate the Takeoff Distance using the equation above:

TD = GR + D50

The values given above are inserted into the equation below and the solution is calculated:

TD = 1000 + 70 = 1,070 (FT)

Example Problem #2:** **

For this problem, the variables needed are provided below:

ground run (ft) = 500

distance to reach 50 vertical feet (ft) = 80

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

TD = GR + D50** = ?**
