Do you mean lock the nose wheel? No. There is always either “low gain” or “high gain available.

Welcome and enjoy.

It is I. And I’m still hanging around.

Very nice indeed.

Not sure what to make of this statement. The real world aircraft does have and uses the ACS for route following, return (either after the last waypoint is passed or when the return button is pressed), and approach down to a height of 50 meters. So ED’s only decision was to model the real world aircraft in that regard. Of course, how the ACS accomplishes that is more complex in the real aircraft than what FC3 aircraft model but the end result (route following, etc.) is there. Just for chuckles I flew with the ACS again this morning with a 15 m/s crosswind component—the max allowable for the Su-27–to see how it would do. It handled it without any problems. Just had to keep my speed above 450 km/hr (which is the issue) until I took control over the inner marker.

Well…it used to work fine and still works fine at times in the present. The modeling of the tone announcing that you are within parameters and the bombs are about to drop is there as well. ED has always modeled CCRP for the Su-25A. It’s just become corrupted and needs to be fixed.

Are these missions that you’ve created yourself? Are they SP or MP? I ask because external views can be closed off through various settings. To be honest, though, I’ve never heard of only the AWACS being allowed through. Why would that be worthwhile anyway? In case you don’t already realize this, you can edit the TRK files to remove any restrictions. They are simply ZIP files with an altered suffix. Open them and use NotePad++ to peruse the files—there are two that contain the reference but I’m not where I can check which they are. Change any references to external views to make them allowed. (Obviously, if they are already allowed in then this is not the issue.) Another thought, does the problem exist with both the MT version of the sim and the old version? Finally, if you have a TRK file small enough, post it here and I or someone else can rummage through it to see what we can see rather than guessing at what the problem is.

I suspect that, as far as landing mode is concerned, there is something wrong with the simulation. I took a quick look at the real world manual and have seen nothing warning you about speed restrictions. That sort of stuff is usually given it’s own WARNING section so as not to be missed. If I was in the habit of using it, I’d probably use the ACS landing mode in bad weather, too. Just keep your speed about 20 km/hr higher (which you should do in bad weather, anyway) than the adjusted speed I mentioned above so that the system can react even more firmly. Don’t forget that it’s the trim system controlling the aircraft. I’d also probably take manual control prior to the inner marker.

I’m lost. What are these two videos proving or disproving?

“Wonky” is probably an apt description for the current implementation of the Su-27 ACS (autopilot). To be honest, I’ve seldom used the ACS myself in the past, preferring to trim and fly the aircraft, and use it not at all currently. Depending on what you are attempting to do, though, it works okay if you’re careful. For barometric hold, you need to be well trimmed. If you’re not, the oscillations you experience will be extreme. (Being within 10 m/s on the VVI is far from adequate.) I don’t mind the mild phugoid oscillations that you get once you’re trimmed, when not using the ACS. Assuming you are trimmed and at constant speed (but not too fast) both baro-hold and route following work fine (assuming the WP transitions for the latter don’t require anything extreme). When I experimented with it yesterday, the transition from enroute to return mode and the return sequence itself worked well. EDIT: (Inaccurate conclusion concerning landing mode removed.) The following was only tested on a PRMG enabled runway. The ACS landing mode does work-more or less-though much differently than it used to. Your speed needs to be above 450 km/hr as you leave the IAF. Once you pick up the ILS at 8km on the HSI, you can begin slowing down but stay above 350. Taking manual control prior to reaching a height of 60 m above the ground would probably be best. It used to be you could leave the IAF at slower speeds but that is no longer the case. The system is unable to adequately adjust to the sudden pitch down requirement as you start down the glide slope at slower speeds. As a result you quickly end up out of phase with increasingly severe oscillations as the system attempts to catch up.

So now I have to learn to walk on water?

Might be minor but still worth the report. Something is not right about the struts.

Then we mostly agree. Like you, I never notice a bounce in a good landing even though the tires leave the ground in the external view. In fact, it was Tin_Rat’s post that alerted me that it was happening at all. Definitely a fun aircraft to fly.

That’s a valid criticism. In my defense, I know that a pitch of 14° at my height above the runway brought the nozzles no closer to the runway than the recommended 10° pitch up recommended for takeoff. And doing so allowed me to land as gently as possible. While I agree that the landing should be made with an 11° AoA (mine was 11.5° and the source I have says “about 11°”), I’m wondering why you state that the approach should be made at 11° as well. Is that your opinion or do you have a source? I ask because nothing I have states anything like that.

A small bounce, as draconus notes, isn't really an issue. In fact, you won't even notice them sitting in the cockpit. You'll only notice them in the external view. So I don't know how much of an issue it is. If you're landing properly, you'll only get a small bounce, at most, from one or both wheels. If you lightly kiss the runway in landing, there won't be any bounce at all because of the slow rebound. The absence of smoke in a very gentle landing is puzzling. The only scenario I can imagine is one in which you are skimming the wheels so lightly over the runway that there isn't enough friction to spin them up quickly. And, then, you finally settle down.

Had time this weekend for 3 quick landings at a gross weight of 13652 kg which is fairly close to @Tin_Rat’s landing weight in his original post. The first 2 were similar to the one I posted above with one wheel coming off the runway. The third resulted in both wheels sticking. Interestingly enough, there wasn’t any wheel smoke either. This was probably the smoothest landing I’ve ever made in this aircraft. TRK attached. (I porpoise in the first minute of the flight. It’s not the TRK misplaying.) Here’s a quick video at 1/8th speed of the few seconds before and after the landing: MiG-29A Senaki--GW-13652kg.trk

Never be afraid to ask a question, especially after you’ve done your due diligence and searched for the answer first. There will always be someone to help. Enjoy the Flanker.

Unfortunately, you read my post before I realized what you were actually referring to and edited it. The TD controller, whatever you call it, is only used to designate the target. TD Control is found in the non-axis section for assignment, while TD Slew is found in the axis assignments section. But both do the same thing. Use one or the other.

The TDC is just that. It moves the TD over the target in Bore and the target mark in the BVR modes in order to lock the target. What it’s called depends on whether you are using the keyboard assignment or binding it to an axis.

Looks like you’re right about that right tire. I didn’t check from that side. From the left side it looked like both stuck. At first I was going to protest that those images weren’t from my track but then I realized that I was using a custom Ukrainian skin. So, of course, you’d see the default Russian skin. Watched your video. From the cockpit, you’d never know that the tires left the ground.

Well… it’s not guaranteed that you’ll bounce. I was both lighter (40% vs 70% fuel) and careful to do this landing pretty much by the numbers (height and speeds over outer/inner markers, threshold etc). TRK attached. If time allows, I’ll try again this weekend with the heavier version. MiG-29A Senaki-No Landing Bounce.trk

I’ll add this track as well. From the cockpit I had no sense that I’d bounced. MiG-29A Landing Bounce.trk

Still…Anything is better than nothing. Great news!

No. You’re not going crazy. I checked from a different angle and the tires definitely leave the runway: As draconus suggested, it’d be best to create a new thread in order to report it. This isn’t the thread to leave it in. Include your track and, if you want, link the above video which is made from your track. Edit: I thought I had posted this 3 hours ago. Just came back and realized I had written it but not posted it. Anyway, I don’t think you have much more chasing to do.

Yes. Over use of the afterburner can boost you into the next century.
