Correcting the throttle curve

Recommended Posts

Hi everyone

 

I wanted to know if there is a way to "correct" the throttle curve on an aircraft. What I mean is, I have an aircraft in which throttle movement is smooth and gradual up to 45% more or less, then extremely sensitive between 45% and 75% and then smooth from 75% upwards. The smallest motion between 45% and 75% causes large variations up and down and I find it hard to set precise N1 settings in that range - this is very unpleasant, as this range is critical for approach and landing settings.

 

I have already tried correcting this with the calibration slopes on FSUIPC. While this has improved the issue slightly, it's still nowhere near fixed.

 

Is there any other way I can fix this, by editing either the .air file or the aircraft.cfg? Or is there another approach with FSUIPC? Please note I do not wish to change power, fuel consumption or drag settings, I just want a smoother throttle curve in the range I mentioned.

 

Any help would be much appreciated.

 

Cheers

 

Antonio

Tables 1503 and 1504 in the .air file contain throttle vs N2 curves (assuming it's a jet we're talking about).

You also want to look at table 1505. your best bet is to do a search on FSdevelopers. As there, there is a lot of discussion about the various air files. Also remember that a jet engine response is much more sensitive at mid to high throttle settings. A 1 or 2% change in n2 at a setting of around 80% n2 can result in a large thrust change requiring almost no throttle movement. You will have to research the engine though to make sure that what you change works. Also bear in mind that the sim makes assumptions of its own so quite often an actual power curve has to be "adapted!".
