Fraud prevention
My company operates 747-400 combi aircraft which are fitted with a W&B system.
Our pilots must make a logbook entry when the indicated ZFW differs more than 10 tonnes from the loadsheet ZFW.
Many times our aircraft took off 10 tonnes heavier than what we were paid for.
Because that´s the trick: 10 tonnes of cargo having a free ride.
Company detectives paid a visit to that specific station (JNB) and voilá, no loadsheet discrepancies anymore.
The W&B system pays for itself I think. Not to mention the safety advantage of a well monitored center of gravity.

Ballpoint.
