Rate of Climb Calculator

Calculate the vertical rate of climb for an aircraft based on thrust, weight, and airspeed

Input Parameters

Calculation Results

Calculation Formula

Rate of Climb = (Thrust - Weight) / Weight × 9.81 × (1000 / Airspeed)

Where:
Rate of Climb = Vertical speed in meters per minute
Thrust = Force propelling the aircraft forward (Newtons)
Weight = Aircraft weight (kilograms)
Airspeed = Speed of the aircraft (kilometers per hour)

Rate of Climb Calculator Usage Guide

Learn how to use the Rate of Climb Calculator and understand its working principles

How to Use the Calculator

  1. Enter the aircraft's weight in kilograms (kg).
  2. Input the total thrust produced by the engines in Newtons (N).
  3. Provide the current airspeed in kilometers per hour (km/h).
  4. Click the "Calculate" button to compute the rate of climb.
  5. The result will be displayed in meters per minute (m/min).

Understanding Rate of Climb

The rate of climb indicates how quickly an aircraft can ascend vertically. It's an important performance parameter that helps pilots understand:

  • Time required to reach a certain altitude
  • Ability to clear obstacles
  • Performance in different flight phases

Important Notes

  • This calculation assumes level flight conditions and does not account for wind effects.
  • The formula used is: Rate of Climb = (Thrust - Weight) / Weight × 9.81 × (1000 / Airspeed)
  • Higher values indicate better climbing performance.
