Flight Computer Reduces G When Pulling Up Over ~350 Knots

[SCU]

When attempting to pull up, more or less in a sudden manner, at approximately 350 knots or more the jet reduces your commanded G's momentarily.

 

You can test this in any mission, but for me personally it happens in Caucuses at any weight, configuration or weather conditions. You will notice that as you pull up when over ~350 knots that you will get an uncommanded pitch down for a moment then it goes back to your commanded G. Hopefully ED notes this issue for future fixing, if they haven't already, as it doesn't seem to be correct behaviour.

Attached track file, using the free flight instant mission.

 

You can skip through my fuel dump phase, which was to increase my G-limit. Notice how when I initiate a sudden (as opposed to gradual) pull up how the G is reduced for a moment then goes back up to my target G, at a given stick position. The same can happen even when I pull more on the stick, as opposed to holding the stick position after the pull.

Does it do the same while using the G-limit override? If not, then this just looks like the flight computer easing on the control surfaces to reduce instantaneous G-load on the wings and then easing the plane to where you want it. I'd recommend another track with the FCS page pulled up on one of the DDIs and try a few maneuvers, one with no limiter override and then again with the override. Watch the stabs and see what they're doing.

Done. It does the same with the paddle override switch (when I pull up with the switch engaged, betty screams "flight controls", and every try after it is with override engaged).

 

I've noticed this behaviour since the first couple weeks the hornet was released, it's only now I've thought of reporting it, since I've seen no one else did. :)

The Hornet will always throw a "flight controls" warning when the G-limit override is activated.

Yep, I already know that. Was mentioning it so that whoever watches the track knows when i begin using the g-override switch.

Any chance a mod can change the missing track tag please? :xmas:

Long time lurker here and first time poster, extremely happy owner of the DCS Hornet, however I'm wondering if anyone else has experienced this same type of "bobble" when pulling aft on the pitch axis in the Hornet.

 

In my search for those potentially experiencing similar control issue, this was the closest thread I could find that seemed to describe what is going on. When pulling back on the pitch axis there seems to be two points where the bobble occurs in flight about 1/3 stab deflection and 2/3 stab deflection. I guess it could be described as a momentary "pitch pulse" in flight path while increasing back pressure on the stick.

 

I'm using a CH Fighterstick and also tried an older stick to see if my stick was potentially the problem, but saw the issue with both sticks, so can safely rule out the stick.

 

Also tried all types of control curves/saturation on the pitch axis with no success.

 

The exterior view of stabs during slow and gradual aft stick input shows smooth stab movement through entire region of deflection.

 

There were a few threads that described some pitch issues associated with the "auto-trimming" option in the settings menu, however with 2.5.6 OB, I'm unable to find that setting any longer, maybe I'm missing something.

 

None of the other aircraft I fly in DCS exhibit this, so just wondering if anyone else is experiencing this or if ED is tracking this? Thanks in advance for any help!
