A-10 stall behaviour in DCS is incorrect

[SCU]

I did a crude measuring, it seems that pilot pulled more than 5 degrees into the chopped tone, that would make him have in excess of 30 AoA units if I calculated correctly, but yeah, correct me if I'm wrong.

I retried the mission with temp 0°C and it seemed much closer to performance of the aircraft in the video when the sim aircraft was above 300kts. Still, the temperature couldn't be that cold in the video.

Plus, in the video he was 276 kts tops.

Try 15C (Standard Atmosphere) which is what the FM is tuned to AFAIK - and then step down by 5 deg to get the performance as close as possible.

Your other option is binary search: 20C is too much (Standard mission temp IIRC), 0 is too low, go for 10.

I had fun doing a mission at 40°C. I could only start one engine normally. I had to high speed taxi to use airflow to help the APU start the other engine. Without increased airflow the engine won't increase RPM past a certain point.

[Yo-Yo]

Is that AoA in degrees? Sorry if I missed something but I can't see the AoA indicator in the video.

But you were barely into the chopped tone, you had just gone from chopped-->steady-->chopped-->wing drop less than a second later, but I won't argue about that too much.

 

Can you tell me what you think about what I had to say here: https://forums.eagle.ru/showpost.php?p=3217697&postcount=169 ?

The pilot has chopped warning, but he increases his AoA even more and no wing drop?

 

You never look at the status bar??

You must have been doing something wrong on start-up because that shouldn't have happened and the real A-10 crew chief part of my died a little reading how you started #2. :pilotfly:

Yes I do, but rarely use it, and I only realised the one in your video a while after my post. But come on Yo-Yo, why can't we do like that pilot in the A-10 vs F-16 video, you know, the bit where he pulls 4-5 degrees more AoA into the choppy stall tone?

You are waisting my time. A-10 is one of the most forgiving planes in DCS as far as you can see.

 

AND NO CHANGES required.

Frankly I do not understand why you so interested in post -stall region. Steady tone is specially implemented as MAXIMUM PERFORMANCE. Balancing between two different tones you have THE BEST performance.

 

But enjoy.

 

[SCU]

I may be wrong by what they are describing..but

Nah, that's something else.

@Yo-Yo, nevermind, I'm sorry I wasted your time. I thought this was a bug reporting section and I spend a lot of time here trying to even prove what I reported was an actual fault/bug/whatever..

As I said before, once you get DCS re-installed, make a video of your flying, with the issue you see. Make sure your control monitor is up and showing, and we can see what you are seeing better. So far you havent really given anything concrete that there is an issue.

I thought that I got my thoughts through by now :s. There have been more than one video posted here where I have pointed out the exact issue, it's really simple it's just the wing drop (I thought it was a famous thing, apparently not lol).

But sure man, DCS is fully updated now, when I have free time from real life things I will be getting out my hotas and reconnect and put up a track.

Excuse me Yo-Yo, I wanted to use this opportunity to ask you a question about what you did in this video, talking about stalls and G's, the A-10 is rated at +7.3G, does that mean it should never be flown above 7.3 or this means, if the aircraft reaches 7.3 or more, it can cause structural damage to the airframe? Thanks.

[Buzzles]

The latter.

[Vitormouraa]

The latter.

 

Excuse me, what do you mean?

[Mud]

The latter = the last of the two items summed up.

As usual. If The maximal G-load is listed 7.3 it means that before this value the airframe is garanteed to be safe during it's lifetime. Generally 1.5 is a safety coefficient, so it means that at 1.5*7.3 you will get structural damage.

But 7.3g is stated for the certain mass, in the video the mass is not standard - 28% of fuel. So the g-limit is higher.

Could be, my second attempt worked fine. However, it is interesting that I could do a windmill assisted start. To be honest, my high-speed taxi was actually a takeoff run that required all of Vazani's runway to get airborne. At 130kts I was committed to climb or crash and the second engine was almost started, so I went for it and completed full start up after airborne.

[NineLine]

Not one pilot I have talked to in the real 76 or 75th has ever said anything about wing drop.

 

Do they push beyond the warnings usually? But I think my point about our controllers still stands, we can and do push probably farther than a real pilot does due to many factors not experienced by a virtual pilot.

I agree with Sith 100% as virtual Pilot you cant help but make inputs no pilot would make due to the lack of feedback.

A-10 stall behaviour in DCS is incorrect

 

Having not read the intervening 6 pages, could it be something as simple as the delay YouTube audio has? Are you seeing him pull further into the chirping when really it's the chirping in the video is delayed from the video?

No, the audio of the Aim 9 seeker, radio chatting and the trigger being pressed with the square block in the top left all indicate synced audio, plus in the time mark I linked he had been in the chopping tone for like hours, so it won't matter if the audio is early or delayed...

Call me an ass, but here's a good video with inside and outside with airspeeds...

 

 

Try going 410kts in near level flight in the DCS A-10...I don't think you can go that fast in a straight dive from 30,000 feet...let alone any where near level flight during a typical American summer...

Nice video. Good to know the A-10 can handle 7.5 G's at 3:50 in, that's a very light weight A-10 in those demos though.

Have you tried the A-10 bare naked and loaded lightly? Its quite a difference. I cant imagine for an air show they are packing much weight, do you?
