Takeoff Distance Calculator

The Takeoff Distance Calculator helps you calculate the total takeoff distance for an aircraft based on its gross weight, ground roll, and initial climb speed.

Calculation Formula

Takeoff Distance = Ground Roll + (Initial Climb Speed / 18) * Gross Weight / 1000

Where:
Gross Weight is the total weight of the aircraft including passengers, cargo, and fuel.
Ground Roll is the distance the aircraft travels on the ground before takeoff.
Initial Climb Speed is the speed of the aircraft during the initial phase of takeoff.

Takeoff Distance Calculator Calculator Usage Guide

Learn how to use the Takeoff Distance Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Gross Weight of the aircraft in kilograms (kg).
  2. Enter the Ground Roll distance in meters (m).
  3. Enter the Initial Climb Speed in kilometers per hour (km/h).
  4. Click the "Calculate" button to compute the takeoff distance.
  5. The result will be displayed in meters (m).

Working Principle

The takeoff distance is calculated by adding the ground roll to a factor that depends on the initial climb speed and the gross weight of the aircraft. The formula used is:

Takeoff Distance = Ground Roll + (Initial Climb Speed / 18) * Gross Weight / 1000

This formula provides a simplified estimate of the total takeoff distance required for the aircraft to become airborne.
