Welcome to Traffic Cone's ERAU Cessna 172 Weight and Balance Calculator!

You are using V3.5.2 What's new?

Fill out the info below to calculate weight and balance for your aircraft!

DISCLAIMER: These calculations are provided as reference, with no guarantee of accuracy, and should be checked against your own calculations. You, as either the pilot in command or acting pilot in command, are ultimately responsible for ensuring accurate weight and balance and performance calculations, and verifying they are within the limits outlined in the Pilot's Operating Handbook and the ERAU Flight Operations Manual.

Rounding: Most numbers in the table are rounded UP to 2 decimal places (except ETA data). Performance numbers are rounded up to the nearest whole number. Climb rate and maneuvering speed are rounded down.

ETA data accuracy: These numbers from ETA are up to date as of March 22, 2025, but may not be completely up to date.
Please double-check with the POH during your preflight or check with the numbers on ETA to ensure accurate calculations.
