707 Pilots,

I need help with some planning and i hope here are pilots that are willing and able to help me.

I have downloaded all the performance maps and want to plan my flights realistic.

Now for the tables i need my takeoff gross weight. But the TOGW is included fuel. and the fuel is the thing i want to plan. so How do i determine the fuel without knowing the TOGW?

Kindly regards,

Rick Winkelman
