investigating After "repair" of landing gear, A-10C pulls heavily to the right.

[Madman1]

I damaged one wheel on landing but I was able to make it to the parking area intact. I shut down, made sure the engines were completely stopped and then used the F8 menu to ask for repair. Got an affirmative reply from the Chief. Waited, countdown started, repair sequence ran. Chief comes back with "repairs complete." I restart the aircraft and get moving. Now the A-10 pulls heavily to the right, much more than it normally does. I know that the A-10 normally drifts when rolling on the ground becasue of the offset front gear but this is much worse than that.

SO anyways, after "repair" I need to hold the rudder to about ten degrees continuously just to keep it on the taxiway or I will end up in the grass. Is this working-as-intended or is this a bug?

Obviously after a repair the aircraft should be brand new, so if it doesn't behave like it should it doesn't sound correct. But now it would be good to know what actually went wrong, so we can figure out if it was actually a bug or something else that went wrong. So, can you replicate it? Do you have a short track?

[Madman1]

What's a "short track?" I can see tracks in my Saved Games\DCS\Tracks\Multiplayer folder but they're all the entire match, not just the incident. How do I trim them down?

[Madman1]

Oh god dammit, the track is larger than 50MB so this forum won't let me upload it. Really, a 50MB limit? Did 2008 barricade itself inside ED headquarters and hold the file server hostage?

Recreate the issue in a short flight, maybe from an Instant Action mission. Quit as soon as the issue is evident, then hit "Save Track" on the debriefing screen.

You can't. They begin at the beginning of your mission and then replay every single input you made.

This is a flight sim forum, not a file sharing site. With thousands of users uploading screenshots, tracks, missions and so on, I'm guessing the servers already have to handle quite the load.

Did the 2020s not tell you about actual filesharing sites from which you can then link the uploaded files?

Anyway, no one wants to watch players fumble around for 2 hours in order to spot one very particular issue. If you can't recreate it in a track that's maybe 10 minutes long, don't bother. Plus, track replays sometimes play out differently than when they were recorded. The longer they run, the higher the probability of replays going amiss. It would be close to miraculous if your tracks of more than 50 MB would play out exactly like your mission, and we'll all just have wasted a lot of time.

Also, please use the Caucasus map, because everyone has it. Make sure your mission doesn't require any mods.

I uploaded it to a third-party server: https://limewire.com/d/VskAK#fw958xMxG8

Ok I replicated the problem, only with two blow tires instead of one. But same result: A-10 pulls hard to the right. And I managed to keep it under 50MB this time so here ya go, fresh new track:4YA_CAU_PVE_V2.141[03_DEC_BKN]-20250903-162244.trk

It's on the Caucasus map. Only "mod" is a RCAF livery but that shouldn't matter should it?

Anyone? Hello?

Oh yes, apologies. After a long day at the office I would have preferred to respond sooner. But I had to watch your 48 and/or 23 minute long tracks, or else all I could have responded with would have been "Hello."

You omitted a few key parts in this initial description, but at least the 23 minute track does clear things up.

Repairs have nothing to do with your issues. The repair works fine.

I'm going to give you a hint without actually answering your question. You'll thank me later.

Just out of curiosity, whats the caution light panel say? I don't have 23 minutes to spend watching the track 

[Madman1]

I noticed that. To me that just means that the ground crew didn't finish fixing the aircraft; if it was actually fixed correctly there shouldn't be any caution lights after the startup sequence is finished. Instead it's showing that they left the right engine and hydraulics borked.... which is interesting becasue I didn't break any of those, just the landing gear. Do I just need to push the caution lights to fix it?

That's also what I saw in the track.

The right engine never finished the startup, and when you taxi on the thrust of the left engine alone, the thrust asymmetry causes a severe yaw to the right. It also means the jet barely gets airborne on the takeoff roll, where the yaw instability should be the least of your worries.

I'd recommend to make sure all caution lights are off prior to takeoff and give your engine instruments a good look-over to check they're all in the green.

That is correct, but doesn't mean the autostart sequence is going to work 100% of the time.

Anyway, in this particular case it looks like a know issue where the engines don't start up correctly when the outside air temperature is around or below freezing.

So the repair didn't cause the issue. The requirement of shutting down the engines for the repair and the consecutive attempt to start them up again caused it to surface, and it wasn't evident before in what I assume was a hot spawn.

The fact that the autostart sequence doesn't detect or report errors plays a role as well, compounded by the pilot's failure to monitor the aircraft systems after the automatic startup sequence.

ENG START CYCLE is still on and all the cautions you'd expect from the right engine being stuck at low RPM.

Ok thanks for the informative reply. I'll let you know if this crops up again.
