How to use this calculator

What to enter

Enter or select the following as requested: Maximum takeoff weight (kg); Operating weight (kg). Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The aviation result is an estimate based on the aircraft, route, weight, speed, wind, fuel, or performance values entered. Check units, aircraft-specific performance data, atmospheric assumptions, and whether reserve, taxi, climb, descent, and regulatory factors are included.

When to use it

Use this for educational or preliminary flight planning only. Never substitute a general calculator for the aircraft flight manual, approved performance charts, current weather, official procedures, or a pilot’s operational judgment.
