How to modify cruise performance in IFDG 767-400

[ecagan 0]

I've started flying the IFDG 767-400ER again and I have noticed that I am not able to get up to the cruise profile of .80 Mach. Is it possible to modify some parameter to increase the engine performance? When the tanks were almost empty, the most I got was .78 Mach. Due to my initial weight from PHNL to KATL, I wasn't able to get above FL 320 either. I didn't know if that sounded right to others more knowledgeable, but seemed that the aircraft was slightly underpowered.Thanks,Eric

You could reduce the inlet area in the aircraft.cfg, which especially helps with power in the flight levels. As for how realistic the end result would be, I can't comment as in most cases heavy jets often step climb when flying with a max pax load and full fuel.Regards,John

767s are reputedly slightly under-powered anyway, but I'm sure it gets to its published figures in level flight. If you really need to do it, an alternative would be to amend the following parameter in the aircraft.cfg file:[jet_engine]thrust_scalar=1.0This increases the thrust efficiency without increasing the thrust rating of the engines, but amend it carefully. Upping it to 1.1 will probably do the job. If teh section isn't there, then just add it.;)

Thanks, I'll give it a tryEric
