Hey mate,
thank for that info. I tested it some minutes ago and can confirm that.
If you use HMD, your HMD crosshair is your marking point for CCRP. If you disable that, your normal gun marker is the point for set a CCRP point.
Did not make sense before the update and does not make any sense now… I also don’t know if I should make a new bug report about the rate, as while the old one is still there and valid (tested F-16A rate in the same configuration and the difference was 0.1 deg/sec in favour of the older model, which is well with in the test error), it has also been almost 2 weeks since I made it and it wasn’t even acknowledged.

Well, the FM changes are live. I’ll ask them about it.

Making a new report sounds like a good idea, but i think they are intentionally going to hold the current f16 till the addition of new stuff, there’s absolute no reason to not change it’s FM after all the proofs and tests made by the community.
No need, just wait to see if they’ll acknowledge the current one.
Both static and dynamic directional stability would come to their lowest at 35 deg AOA, which means the most yaw departure susceptibility. Any sideslip developed (induced by adverse yaw, kinematic coupling, etc.) at such an AOA would just increase rapidly and went out of control. That’s why the irl FLCS incorporates a Yaw Rate Limiter which overrides pilot control above 29 deg AOA (or 35 deg AOA for DFLCS equipped with sideslip feedback) and automatically deflect both aileron and rudder to kill yaw rate.
Static directional stability is already at neutral between 25-30 deg AOA. Any sideslip developed would increase steadily. Stabilizer effectiveness would also be reduced with increasing sideslip, to a point where the stabilizer would no longer suppress the pitch-up tendency due to the decrease of pitch-down effectiveness and also inertia coupling during the rolling and yawing motion.

@iso_gate So why was available AoA increased during this major patch? We already knew it was severely overperforming in high alpha performance and stability?
@Giovanex05 Apparently it is only a suggestion to lower the sustained turn rates to realistic values and model the F-16 similarly to what they’ve done to the M2K and MiG-29… accurately…

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-16C;
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?
