OK....what is a 'unit'? I could look it up, but I'd rather you tell us, in pounds.
A B757 has a Max Gross Take-off weight of about 250,000 pounds, depending on model.
Let's assume the Empty Weight is about 101,000 to 105,000 pounds. Now, let's add the weight of the fuel....say 80,000 pounds.
HOW MUCH 'payload' do we now have?
Here's a hint...for airline ops....Each passenger is given an 'average' weight of 170 lbs....this is the 'winter' weight, it's lower in the
Summer...OK, after you finish laughing (I am NOT making this up....this is FAA approved!) Each average checked bag is given a weight of 35 lbs.
THIS is the 'PAYLOAD' that is put on the manifest, before every passenger airliner takes off.
Here's how it works....there is the Aircraft Operating Weight, which is the airplane's empty weight, plus required crew and supplies, meaning Galley
weight....that is the OEW (Operating Empty Weight)
OEW plus FOB (That's Fuel on Board). These are required, and non-negotionable.
The rest, is the allowed payload. It's that simple. Once have the OEW, plus the required fuel.....the rest is Payload, up to the Maximum Taxi
weight, and then the Maximum Take-off Weight.
See, we are alllowed to leave the gate above Max Take-off weight, assuming we will burn off a few thousand pounds of fuel, before take-off, thusly
reaching the Max Take-Off Weight, prior to take-off.
Sorry if tis is too complicated....facts can be confusing, sorry.....
