Zero Fuel Weight

[TonyC]

The Maximum Zero Fuel Weights for our 727s were 140,000lbs for the B-727-2S7 and 141,000lbs for the B-727-2M7. In the manual under "Limitations".

They gave you a MANUAL!

Man, do I feel ripped off!

Ha, I know what you mean...it was a different world back then. The bad part was...we were supposed to know what was in it.

Don't you use your ZFW to figure your gross weight?

ZFW + Fuel on board = gross weight

The formula is correct, but I don't do it. The Ramp Agent plugs the numbers in the computer (the computer handles all the limits automatically) and the Weight & Balance manifest is printed out for me. We plug the TOCG and TOGW into the performance computer along with the environmental variables, and it spits out Takeoff Performance data. I sign it, and we close the door.

Wouldn't you need it if you get a hold or something and got to figure holding speed/epr/fuel flow? You never know

Well, if you really wanna get down to the brass tacks, I can add the ZFW in thousands of pounds to the Fuel Weight in thousands of pounds, subtract 100, divide by 2, and add 107 to get the V ref for the Gross Weight. But again, the Flight Engineer has a table for doin' all the guzzinta's and a computer for spittin' out all the speeds, so I'm really only backing him up.
