:'(
When you start planning a flight you need to know:-

1. Empty WT
2. Payload Weight

How are you matching this up with CS757?
What aircraft profile are you using and how do you know what the ZFW of the 757 is?
The ACE isn`t much help as it dosn`t load the correct amount of weight and dosn`t give as much info as the LVLD767 weight planner does.

Please help.
