Trim problems in F-16

[marcelbrabson]

I'm having trim problems when I fly DCS F-16 & F/A-18. I have a Thrustmaster Warthog setup and have the trim settings mapped. But no matter what I do while in flight the jet wants to descend. Does anyone know how to rectify this?

Make a new ME mission with an F-16, air start. Start mission and active pause. Look at the needle dials on the aft left console when you actuate the trim directions. See that the needles move in response.

Will do. Thanks

I had the same issue with both jets as well. Turns out I had inadvertantly assigned nose down trim to a second button that was already in use. Unmapped and all down trim issues went away.

Assuming you don't have any control mapping issues, this is how trim should work in the Viper (and it does):

 

With less than 15 units of AOA on the jet, the flight control logic is looking for G inputs. In level unloaded flight at less than 15 units of AOA, one click of trim = 0.1 Gs.  So the jet will try to hold 1.0 Gs in level flight with no trim input. If you give it one click of nose up trim, it will try to hold 1.1G. 2 clicks is 1.2G, etc. Same for nose down. So, if you have the jet behaving oddly, unload the pull with the flight path marker on the horizon and look at the G meter in the Hud.  If it reads something like -0.5, then you need 5 clicks of nose up trim.

What's a "click" of trim? You mean a dot on the scale?

Click as in a push on the trim hat on the stick.
