Aircraft file type for the cdu

Hi

i have some query s about the aircraft file type that we use for the CDU.

I want to write the correct values for the aircraft model that i use.

I need some help in the follow.

The parameters in the aircraft file are:

NETWeight=
Payload=
Fuelmax=

the values of the airplane that i use say the follow:
All the follow values are in pounds

Empty weight : 314,000 pounds
Payload :60,810 pounds
Fuel : 267,836.81 pounds
Cross weight : 642,646 pounds
Max.gross weight : 656,000 pounds
Max allowable fuel : 269,339.99 pounds

--------------

2.the follow equivalence is correct:?
NetWeight is the Empty weight ------------>314,000 pounds
Payload is the payload -------------------->60,810 pounds
