Plan Loads With Confidence
A weight and balance sheet protects every trip. It turns scattered loading details into one clear center of gravity result. This calculator helps you review empty aircraft data, crew, passengers, baggage, cargo, and usable fuel. It also separates ramp, takeoff, zero fuel, and landing conditions.
Why Balance Matters
Weight alone does not show the full risk. A light aircraft can still be unsafe when weight sits too far forward or too far aft. Forward balance can increase control force and landing speed. Aft balance can reduce stability. Both problems matter during climb, cruise, and landing.
Use Moments Carefully
Each station has a weight and an arm. The arm is the distance from the reference datum. Multiplying them gives a moment. Total moment divided by total weight gives the center of gravity. The same rule works for pounds, kilograms, inches, or centimeters when units stay consistent.
Fuel Changes The Answer
Fuel often sits at a fixed arm. As fuel burns, weight and moment both change. That is why this tool shows ramp, takeoff, and landing values. Taxi fuel is removed before takeoff. Trip fuel is removed before landing. The landing balance may differ from the takeoff balance.
Limits And Envelope Checks
Entered limits are compared with each phase. Maximum ramp, takeoff, and landing weights are checked. Forward and aft center of gravity limits are checked too. The result shows warnings when values fall outside the entered envelope. Always compare the output with the approved aircraft manual.
Better Record Keeping
The CSV export helps save the load sheet. The PDF option creates a simple record for dispatch notes, training files, or trip folders. Keeping each calculation can help explain decisions later. It also makes repeated routes easier to review.
Common Input Checks
Review one unit system before calculation. Check that arms share the same datum. Confirm that baggage weights include containers. Small entry errors can move the final center of gravity quickly before departure.
Practical Use
Use measured or approved station arms. Avoid guessing baggage locations. Enter the actual fuel density used by your operation. Recalculate when passenger seating, baggage, or fuel changes. Treat this calculator as a planning aid. The approved flight manual remains the final authority.
