Hey, when using TOPCAT, I always get thrust figures that are way to weak to keep the bird in the air. It always uses the full(and I mean full) runway on takeoff and the aircraft does not climb properly. Could somebody post a screenshot of his TOPCAT settings for the 763?

A few posts back I mention how to configure it. Never use Derate + assumed.

I know, but when it comes to a heavy take-off, the derate causes my aircraft to stall when handing over the control to the autopilot when the acceleration is still to be passed...

Look at the EPR difference - I have to enter a temperature of 29 degrees to get the EPR of 1.50 (which is the value that TOPCAT gives me for an assumed temperature of 44 degrees)

The Topcat Values don't agree with the CS 767, for that reason I match based on EPR and not flex temp.

The EPR vs Temp also not match the simple table I can find on realworld table find on both FPPM and QRH Sad
