Total Moment Calculator
Compute the moment of a weight applied at a given arm.
Description
Calculate the signed weight-and-balance moment from one weight and its arm from the datum.
Total Moment Calculator calculate the signed weight-and-balance moment from one weight and its arm from the datum.
Use this for an individual loading station before summing moments and dividing total moment by total weight to obtain center of gravity.
When to use Total Moment Calculator
Use this for an individual loading station before summing moments and dividing total moment by total weight to obtain center of gravity.
How it works
Moment equals weight multiplied by arm. A negative arm produces a negative moment, preserving the chosen datum convention.1
Interpreting the result
Keep the input units, direction conventions, encoding, and ordering rules visible when reusing the result. Preserve the full returned value for downstream calculations and round only for presentation.
Assumptions and limitations
Use one consistent datum and compatible units across every station. This one-station calculation does not establish loading limits or certify the aircraft is within its envelope.
