Alpha Call-up
Alpha call-up in the AIDS for FAC calculated gross weight is GWFL for weight in pounds, and GWFK for weight in Kilo's.
We use standard weight that aren't too realistic and at very light weights, say a ferry flight, the FAC calculated weight is very close to the weight on the load sheet. With more and more passengers or bags the difference increases. In the summer with a full load in the A320, 5,000 pounds difference is common at our operation.
