FLC Issues

Recommended Posts

I am not quite sure how FLC mode is supposed to work. I do understand it is not the same as an auto-throttle, but I have been having issues with the plane pitching way up or down when it is enabled in cruise. Is this a bug or am I not using it correctly? I also own the Embraer Phenom 300 from Carenado and I do not have the same issues with that aircraft. The aircraft also fails to hold altitude with FLC mode on.

FLC mode is not intended for use during cruise. Its designed to cause the aircraft to pitch up or down to hold a selected airspeed during CLIMB or DESCENT.

Ok thanks. Is there a better way to manage speed then? I feel like the aircraft is really sensitive to airspeed changes when it is managed manually. Unless its just my joystick that is causing the issue.

You're correct in your assessment that the aircraft is very sensitive at the upper end of the throttle range. A tiny movement on my throttle also causes significant power / fuel burn changes.

 

Not sure if there is a fix...... I usually fine-tune it to my planned fuel burn, then just make sure I don't touch the throttle until descent. Often just nudging the throttle-base on my X52 will change the numbers.....

 

Perhaps someone else has any ideas? I suppose it might be possible to create a profile through FSUIPC and maybe alter the control curves...but I've never played with that.

I was actually able to solve the issue for the most part by making finite changes using the "F2" and "F3" keys. That allows for more precise changes in N1. It is not a perfect solution, but it works for the most part. Not sure how they do it in the real world though. But thank you for your help.

No problem!  Glad you could make it work

 

I can almost guarantee that this issue doesn't exist in the real world. Throttle response is likely much more linear (and the Fuel Flow readings on the MFD actually work).
