Default Calculating Airliner Fuel/Payload

hey again guys,

for any of our real airline pilots, (i know this is a dumb question, but i need to know ), how do you calculate your aircraft's required fuel, fuel burn, payload, and estimated flight time? any help would be great.

I worked weight and balance at JAL in SFO for a while, the way we did our load plans was actually quite simple. Figure out how many pax are booked, estimate 165 lbs each, and two 30 lbs. bags each. Figure so many bags per LD3. It was all a guessing game for the first two hours or so, until we got our cargo final. Then we'd make some final adjustments to the load plan, give the thing to the dispatcher, and he'd take it from there. It was actually pretty cool to watch it all take shape throughout the process. Sometimes we'd be WAY off, sometimes spot on.

... and then we'd get the magical 26.0% MAC every now and them. That's when the dispatcher would usually take me to lunch after work.

... ahhh, I miss those days!

My company uses a computer system for flight planning fuel burn...It looks for a routing that is most economical and feasible based on a planned payload...Then as departure time gets closer we use an onboard computer to make the final weight and balance calculations for performance based on airport conditions...Runway, obstacle, known payload, and weather....On the paperwork I receive there is an adjustment to the fuel burn if the payload is different from the planned payload...
