At least they acknowledged it, better than it staying without label… hopefully they won’t say “fixed in last update” as I didn’t have the time to upload the test for the current client and update the bug report
So basically IRL the F-16 FLCS completely took control of ailerons and rudder when AoA was above 29 degrees, but didn’t actually stop the aircraft from getting to 29 degree AoA in the first place, especially given that it loses pitch down authority above 25 degree AoA?
Then at higher AoAs than 35 degrees the F-16 should either flat spin or roll itself over and point the nose towards the ground

F-16MLU “China”;
F-16D Barrak II;
All seems fine to me, only thing I noticed is if you use the weapon selector the sight will default to CCIP even with a CCRP point set. You can swap the sight back to CCRP using the “Y” menu.

You still got the AOA limiter but it can be defeated by pitching and rolling the aircraft at the same time, which is also known as inertia coupling maneuver, that creates pitch-up moment with increasing roll rate and AOA. An example:
Once you go beyond the 25 deg AOA limit, things go south very quickly as there’s a strong instability region seen on the Cm curve. Chances are you’re thrown to the post 65 deg AoA region and got just enough pitch-down momentum to recover the aircraft, or you get stuck in a deep stall as demonstrated in the video.

Hey Gunjob,
thanks for your attention. But the bug appear only in the last patch before the “kings-update”.
But now it works great. Also the implemantion to the HMD is great.
greetings

According to the Cm curve I posted above, the F-16 do have the ability to generate pitch-up moment until ~65 deg AOA by full stabilator deflection. Coupled by the moment of inertia of pitch/y-axis (Iyy), it’s possible for the aircraft to overshoot 65 deg AOA momentarily. I would say an instantaneous 70-90 deg would be possible, depends on the gross weight/inertia. But it doesn’t have the lateral-directional stability available to steadily fly the AOA.
GAS out.
Love that folks originally said that the dev F-16s had no actual tangible change on dev and are now clamoring that the instructor, by design, is allowing the 16s to bypass FCS limits and control departures.
Is the heading indicator on the F-16C HUD still 90 degrees off?
Amazing detailed and informative video from Real Engineering on the F-16 dropped today.

I remember they did one of these on the Abrams and managed to be littered with inaccuracies. Often you’ll find a similar level of quality information on wiki, more so if you check the references at the bottom.

I spy the extra CM pod, anyone have info on that?
On the outboard wing station above the Sidewinder?
It’s the housing for the AN/ALE-50 which comprises a set of towed IR and, or DECM sacrificial decoy(s) of various designs.

Datamine shows a 7% reduction in Oswald’s efficiency for the F-16s. Should fix the overperforming low speed sustained turn rate a bit… The high alpha has not been corrected yet. I await the day deep stalls are modeled.
Forgot to mention a reduction in “ClCritHigh” value from 1.75 to 1.7
As well as reduction in “MultMachMax5” value from 1.2 to 1.12
dunno what multmachmax5 is but iirc ClCritHigh is lift at high or “critical” AoAs
Apparently multMach5 is drag related, which means lower might improve performance? Hard to say since it’s supposed to have the sustained turn at low speeds reduced.
@Giovanex05 -edit- Appears the high subsonic sustained turn rate is correct. I may have some sort of glitch where the HUD isn’t updating the fuel quantity when it’s adjusted in the localhost dev commands.
I’m just not so certain the reduction in weight of the aircraft warrants the low weight sustained turns it can achieve. I’ll have to look into it for both the F-16s and the MiG-29SMT since the aircraft weight has a pretty big effect on the turn performance. I don’t think there is a disparity with the SMT, but perhaps there is something going on with the F-16 since they modified the relaxed stability per my report.
From the test I have done the F-16 performance seems to be somewhat in line with what it should be, didn’t do any extensive test though.
Max AoA seems to have been fixed as I struggled to exceed 36 degrees AoA.
They didn’t really adjust it much, I’m seeing more than 40 degrees still and no modeling of the deep stall
