Constantly drifting upwards

[Dionysus 🐭]

I don't know if this normal or not, but if I want to maintain a level flight, I have to constantly push forward on my flight stick. If I don't, the jet ends up going upwards. Is there any fix?

Which aircraft? It's likely because the aircraft you're flying does not have fly-by-wire and you need to trim it according to the speed, in order to keep level flight.

have you tried to use trim to stabilize?

Nope, how do I do that.

Search in commands for TRIM nose up, nose down, L wing down, R wing down (the spelling may differ a little depending on which aircraft we are talking about) and bind those four to different keys. When you accelerate, the aircraft's nose tend to go up; hence, TRIM nose down. Viceversa when you speed down. Similarly, you may need to compensate the wings when you asimmetrically release ordnance.

Go into adjust controls and figure out what you have your trim up, down, left, and right binded to, if you like the binding it pre-selected, keep it , if not change the buttons. I set mine up so that it is right next to my view adjustment hat. Then when you are in flight, adjust your trim accordingly. You should note that trim is something you will constantly be adjusting. After take off, in flight, configuring for landing, you trim the aircraft to a speed, not an attitude. so with every variation of your speed on most aircraft, you will either see your nose start to climb or drop ever so slightly. As that speed increases or decreases, the pitching motion will increase as well. Just a matter of flying the aircraft, getting a feel for how they respond at different speeds, and what speed you want them trimmed for. I'd say start working on getting it trimmed to your liking for speeds below 350kts first, then move on to faster flight.

Hi, you have to use trim to balance your aircraft. The reason is the center of lift is not in the same point as the center of gravity.

Those can not be in the same point because the aircraft woul'd be very unstable and also the center of gravity is changing because the aircraft weight is aslo changing.

So, if you fly straight level foward and increase thrust, the common aircraft will not fly faster but will start climbing. To fly faster you have to push nose down. If you don't want to harm your hand, you have to use trim. The trim controls the trim tabs or the whole main flight control surface. It depends on used technology.

"By definition, to "trim" an aircraft is to adjust the aerodynamic forces on the control surfaces so that the aircraft maintains the set attitude without any control input."

The trim belongs to secondary flight controls as the flaps, slats, slots, spoilers and speed brakes.

Depending on the jet some autopilot modes will help you keep level / direction.

Thanks for the advice, i'll set the trim and attempt the tutorial again.

I sometimes have the same problem with the SU-25T when I release the autopilot in non level conditions. The problem causes a force in pitch, mostly upwards, but sometimes even rolling or yawing. I think that maneuvering with the autopilot set or changing speed drastically is the cause for such kind of issues.

What I do is setting it back to level flight (ALT-3) and that fixes my problem in DCSW. After I have the aircraft flying level I just turn the autopilot off (ALT-9). I have no idea this works in aircraft like the F-18 or F-16. But it probably works in several Russian aircraft.

As far as I know, it doesn't work this way (in game) in Su-27, Su-33 and MiG-29. The default trimmer bind keys are "RCTRL + ;" for "UP", "RCTRL + ." for "DOWN", "RCTRL + ," for left and "RCTRL + /" for "RIGHT", at least for "Flaming cliffs 3" planes.

By the way rolling and yawing can occur after dropping a bomb or shooting a missile from one wing only. Because the other wing will be heavier and it will also change the aerodynamics of a plane. The airflow around the wing that have more weapons will differ from the airflow around the wing with less weapons and it will result in unbalanced air drag effect.

yup simple fix

go into game options
then gameplay
click on Simulation button over there (its like bottom of left column on that page)

What you are talking about is related with trimming controls bindings in DCSW.
What I am describing above is the lost of pitch, yaw or roll controls when you mess it with the autopilot (like forcing direction or height while the autopilot is on), or due to big changes of speed and extreme direction change.

In most cases this happens right before or even while you are in combat (in my case CAS mostly) and there is no time to fine adjust trimming, because you are turning and diving and climbing like crazy, dodging IR SAMs and AAA.

It´s the way I have been managing for weeks with the SU-25T, these issues described by aaronth07. And it works perfectly.

Yes your way is good. But what I'm trying to tell, that it doesn't work the same way with Su-33 for example. If you press the "LAlt + 3" in Su-33 while flying, it will bring the plane to a horizontal fly, but once you press the "LAlt + 9" it will return to the prevous trimming that you did before engaging autopilot. So manual trimming is necessary for some planes.

I understand the way you describe it here for the Su-33.
The SU-25T issue I am talking about is mostly not a problem of trimming. It is some sort of disadjustment caused by the autopilot. An issue with a sort of bug or an abuse of autopilot handling. At the beginning of DCSW I used the trimming to fix it and it worked some times and others not.
Unfortunately I do not have yet the SU-33, so I can´t replicate the same situation.
