ILS 50% Working

[BlackMagic]

Hello All

I have noticed the ILS hasn't been working correctly for a while now. While intercepting the ILS on approach to the runway seems to not to receive centerline information. Glide slope interception is received but center line needles on the HSI doesn't represent the center of the runway correctly.

 

In example I have found a older ILS training video that shows the correct function of ILS in DCS. Starting from

you can see the center line move on the HSI and ASI in sync. Here is another

showing the same. This no longer happens.:joystick: The only current work around is to use HSI for center line reference. Currently if you bank left and right while on final approach the center line (Yellow) needle will also move left and right. Which isn't suppose to happen.

 

Second issue I have noticed is the ILS no longer tracks out at the same distance. In the second video you can see that he has captured the ILS at about ten miles which is correct. Shown

. On recent flights I have capture the ILS at 3 - 4 miles. Which is unacceptable for night and IFR approaches.

 

This currently takes away from the IFR approaches that I use to love to complete in this SIM. I will record some approaches to show the difference of the video compared to what is happening currently.

 

If anyone is having this same issue please comment and post so we can get ED to look that this. I will record my findings and reply to this post. Thanks.:helpsmilie:

The change in the crossbar behaviour is actually a fix of a long-standing bug. It is not an ILS repeater, even though it was implemented as such in DCS, but rather command steering - a flight director. Well covered in these fora, search and ye shall find.

Thanks for the response

 

I agree the needle is a flight director while not in the ILS mode, but when ILS is selected it is a repeater for centerline and glide slope. The bug is that it does go into ILS mode when selected. I fixed this system for 8+ years in F/A-18C, trust me I know how they work. If the needles move when the pilots banks according to attitude in ILS mode. The ADI is bad. In civilan applications is exactly the same. Show

with ATP. The only difference is HSI is only used in this example. Military Applications use the ADI to repeat that input.

Just go to DCS: A-10C Warthog » Bugs and Problems » A-10C Avionics and Weapons and look for "ILS". There are several, long threads about ADI and ILS and how they did work in the past (ILS repeater) and how they should work (command steering bars). Several people - who have proven to be a capacity (i.e. RL A-10C crew chiefs) when it comes to the A-10C and it's avionics - support the idea that the ADI in ILS mode has to show steering bars.

I have also found another post that show exactly what the currently issue is with DCS ILS needles. Shown

. Thanks for the previous post by Mr. Fabrice Nizet.

The idea behind me pointing you to these threads was not that you simply re-post the issue there, but that you actually _read_ what was written there. :doh:

 

There are several postings in those threads that explain why the ADI should work as flight director when in ILS mode and not as ILS repeater. If you have counter arguments, then bring them on - simply saying that it is wrong is not enough ...

 

Afaik the DCS manual AND the RL dash-1 only speak of "steering bars" and it took ED quite some time and efford to correct the previously errorneus behavior ... but all this can be found in the mentioned threads ...

What I read was more misconceptions of the system operation. I understand the hard work ED has put in. If you remember that this sim was originally made for the military. When a military contract is made there are specific guide lines for operational training. I was part of that training process for the military. I trained countless military personnel on the operation of this specific system. So if ED doesn't want to listen to me or any other vet who is either currently part of that process or use to be. Well I have nothing left to say. It will just stay broken like many other parts.

I can vouch for BlackMagic's credibility.

 

It is my understanding that civilian air craft do not do this, but military aircraft do.

[Rongor]

As already said, these are steering bars in the ADI. You find ILS information on your HSI only. And that is why you have to select ILS on the NMSP before. No bug.

So it's not the result of a bug, its just wrong?
