1. The autopilot is now much more effective at much lower IAS values. Where it used to have to be engaged at above or equal to 560 Km/h, that figure now is significantly lower, somewhere between 320 and 340 Km/h IAS. At around 330 Km/h IAS a slow but significant yaw & roll sets in, particularly at very high altitude, but if IAS increased above ~340 then it damps out.
THEY FIXED THE AUTOPILOT!!!! WOOOHOOO!!!!!!!!!!!! :sorcerer:
This has opened up the region between 10,000m and say 12,500 - 13,000m to autopilot use for high-altitude cruise. If you're going up there then I'd advise very gradual rates of climb and to keep your IAS as high as possible. This will make flights beyond 1,500Km in range much, much easier now than they were before where the autopilot could only really be used up to 10,000m for safe cruise at 85-87% RPM.
2. The AOA limited / stick pusher is now significantly more proactive in limiting AOA and hence G values to safe levels. Essentially the limiter will now save you under any weight / speed conditions, as it did before, but now with a much wider margin of safety. For example, I was in a descending turn at around 5,000m, ~1.3M with full stick back. G was limited to roughly 5.5-6. Weight was 27,720Kg.
3. The effect of turning off the limiter with the "W" key is now much more pronounced. If you turn off the limiter the ACS will (obviously) allow you to go to maximum aerodynamic G values which can and will destroy your airframe. Changing the ACS to manual mode with the "S" key still does what it does. Use above ~450Km/h is not advised unless you know exactly what will happen when you switch to manual mode and are ready for it. Otherwise, instant G lock and pilot death and/or airframe destruction.
All in all the Su-27 has become much more care-free, but with the ability to push beyond what the ACS wants to allow you to do, if you're prepared and are able to fly manually within the safety limits of the airframe.
Awesome work ED!!
Edited to add: This is it! This is the ACS update I've wanted for months. The only things that are ever going to prise me out of the cockpit of my Su-27 are the Spitfire and the Typhoon...

ASC inserito, premo S e lo disinserisco (Direct Control)...
la W (che sembra mantenere l'ASC ma senza limiti di G) è una cosa che già c'era e me la sono persa o è una novità, o non ho capito una minchia?
Ironhand;2943327 ha scritto:After some quick and dirty tests this AM it seems that:
1) the limiter now holds you to rough maximum of 120% of max operational Gs
2) AP: "A" and "LALT-6" (the 2 Route Following modes) behave differently. "A" follows the route AND assigned altitude. "LALT-6" follows the route but holds your current altitude.
3) The 3 "Barometric altimeter hold" keys all work the same and hold your current altitude.
4) LALT-3 (Wings Level to Horizon) does what it's supposed to do--level your wings.
5) "A" will now take you smoothly in for a landing. You need to be landing by the numbers though. No zooming in and expecting to stilll land safely. Darkfire, my landing weight was somewhere around/below 23,000 kg. I was under the impression that the AP was supposed to release at 150 m altitude but it didn't. It brought me right down to touchdown and I had to manually disengage it on the runway.
EDIT: I have to admit to rarely using the AP. So it may be that some of what I think of as different really isn't. But the slow speed handling of the AP is definitely fixed.
