Approach ACS

[dresoccer4]

hi! can anyone tell me how the approach ATC actually works, or point to a good tutorial? i'm struggling with it.

 

thanks!

If you're referring to the Automatic Carrier Landing System (ACLS) it's not implemented yet.

i'm sorry, wrong acronym! I meant approach ATC, the auto throttle :cry:

also not implemented

If you are just asking about Auto throttle, just assign the button to your hotas and when pushed it will keep your current speed. I use it all the time when flying lead, especially when in the stack (250 knots). Moving the throttle alot will turn it off.

I believe auto-throttle in landing mode will pretty much work the same way. When you're in landing configuration (gear down, flaps full) just hit the ATC button on the throttle.

 

I've heard both that this mode isn't implemented and that it is implemented but not working right. I'm unsure which is true.

it definitely does something, the throttle moves, and it feels like the sticks does too? but yeah i thought i was doing it wrong, but turns out it just not behaving correctly

i dont think you'll need ATC for approach just use pitch trim its better

ATC Cruise - works OK, but Power Approach doesn't work like it should. Power approach - when Flaps are in Full - still WIP.

With gear and flaps down, the ATC button on the throttle should maintain AOA, instead of speed. It doesn't work correctly now. Every time I tried using auto-throttle during an approach, it tried to kill me.

Because its not tuned and it's WIP.

I agree. I posted my comment the same time you posted yours, I hadn't seen it.

Well, I tried ATC approach mode a couple of days ago and it worked as intended. First fly on speed AOA, trim for that AOA and then engage ATC while flaps full. - You change you flight path with the stick, but use only minor corrections. ATC approach mode will just look at your AOA and adjust power accordingly. Easy to over-control. If you make changes more than 1 or 2 degrees ATC will have trouble catching on-speed again, resulting in oscillations.

 

BUT

 

After that I tried it two times more - both didn't worked. ATC approach mode just went to IDLE power and at 120KIAS I had to disengage it and land manually. I will investigate more on that topic. Maybe I was doing something wrong or a criteria wasn't met. It was strange that ATC only engaged when pressing the button a second time. (Edit: Maybe you need to engage ATC cruise mode in flight at least once for it to work?)

 

Oh yeah, no throttle movement with ATC (auto throttle control) and if you want to test ATC approach mode for yourself, try it in at least 1,500 AGL, so you don't die. :-P

The double press after cold start bug is known.

As for the ATC Approach working once; I suspect you didn't have full flaps on the one time it worked as it is known that it will work with half flaps.

Hmm, I don't want to deny this possibility, but as I use the TM Warthog Flaps Switch for Flaps, I am relatively sure I was in flaps full. My Approach speed was also around 132KIAS. Wouldn't that be to low for flaps half?

 

Nevertheless I will test around. Tomorrow I have surely time. Maybe I can even fly today.

[sebihepp]

I did some tests and this is what I found out:

 

ATC Approach Mode with Flaps Half works perfectly. (Couldn't test initial nose down - see below)

 

ATC Approach Mode with Flaps Full is kinda working.

On first engagement it reduces throttle way too much resulting in nose down and loss of altitude. If kept on it will return to a stable on-speed AOA after a while.

Then it works nearly as designed - but the throttle is not aggressive enough. It would need to correct way more.

 

From my point of view it is nearly finished. They only need better response in throttle to AOA changes with flaps full - maybe the issue with the initial drop will be solved through that.

Any updates from the Devs on this topic? Do you work on it or is this part on ice? Any suggestion when it will be finished?

By the F14, it works there, sort of, somewhat, you'll and up on the deck, surprisingly.
