Frogfoot1606687865 Posted October 18, 2010 Posted October 18, 2010 Hi , I was trying an ILS approach to Kobuleti last night in poor visibility and could not get it to work as expected. I set the freq 110.30MHz in the ILS and made sure it was powered on, Set the course bug for 70deg (I zoomed in on the f10 view and used the ruler to determine the exact runway orientation.) I switched on the ILS mode on the NAV mode select panel, and flew towards the steerpoint marking the Runway. After a while I picked up the ILS signal and got steering cues on the ADI, I flew down the glide slope following the cues. Feeling really pleased with myself.... Until I clear the cloud base and I am not aligned with the runway at all. I am heading for the threshold but offset about 5 degrees to the stbd. This resulted in a missed approach, I found I had to adjust the course knob to 65 on the HSI to compensate. I found the steering cues to be very different to what I am used to, the vertical cue was Ok once I realized that that changes with Roll angle rather than heading, but the Horizontal cue seemed pegged out of sight until the glide slope indicator (GSI) was very close to being lined up. Then it flashed into view and as soon as I was very slightly off the GS it vanished again, It seems slightly over sensitive, The small GSI tick on the left of the ADI was much more useful.

RogueRunner Posted October 18, 2010 Posted October 18, 2010 I have not tried the ILS in this yet but the real world version has nothing to do with what your course setting is, the needle will just prob not point straight up but the localizer and glideslope should work normally. In your example, was there some deviation on the localizer or did it show you lined up correctly? I'll try it tonight in the A10 ans see what happens. Remember, the localizer needle covers 5 degrees deviation on each side only so they will only get active in that zone. The further you are away the less sensitive the needles will be for deviation. As you get closer they will get more sensitive. With the price of ammunition these days do not expect a warning shot.
SinandGrin Posted October 18, 2010 Posted October 18, 2010 I have tried an ILS approach and I too felt the sensitivity in general, for both the localizer and the glideslope were a lot more sensitive than they would be in real life. Also the OBS knob in real life has no effect on the CDI indication of the localizer it simply helps the pilot with situational awareness to align the CDI with the extended centerline of the landing runway (you are correct RogueRunner) but in the game it was affecting the CDI's deviation which it should not do. I had to fly the approach visually the first time to "find the best" OBS setting that would give me reliable localizer cues to compensate for this issue. Once I had that dialed in it was ok, other than the extremely over sensitive glideslope and mildly over sensative localizer. All in all it was do-able to get the plane on the ground, but not 100% correct or realistic in my opinion, but maybe military ILSs are slightly different than civilian hardware, although I doubt it.
CrashEd Posted October 18, 2010 Posted October 18, 2010 (edited) I noticed this the other night whilst performing an ILS approach in to Kobuleti. If you follow the ILS localiser to the needle, you'll end up approx 5 deg off course (equates to about a plane width to the right of the runway). I even took a screen shot as I was quite surprised (will post later). The localiser sensitivity of the needles seems about right, so I don't think there is anything wrong there however the GS does seem a bit tetchy. Could be WIP so I'll await the next beta before I make any decisions on it. I love how you can pick up the localiser back course, particularly when you circle around after a 'touch and go'. Awesome.

RogueRunner Posted October 18, 2010 Posted October 18, 2010 I but in the game it was affecting the CDI's deviation which it should not do. Ahh thanx SinandGrin, Yeah, that most certainly is not correct. WIP I guess then :music_whistling: With the price of ammunition these days do not expect a warning shot.
CrashEd Posted October 18, 2010 Posted October 18, 2010 Incidentally, has anyone got the outer/inner marker beacons to annunciate? I tried enabling/turning up the volume on the intercom panel, but no joy as yet. Could also be WIP...
asparagin Posted October 18, 2010 Posted October 18, 2010 Sounds like the ILS is directing same as TCN. For TCN it makes sense, because the TCN beacon is between the runway and taxiway and you get a 5° deviation in respect to the runway. ILS should direct you to runway though, must be the beta gods.

You may well be on to something here. Lets hope it's fixed in the next beta (assuming it's not something stupid that I'm doing ;))
kylania Posted October 18, 2010 Posted October 18, 2010 This resulted in a missed approach, I found I had to adjust the course knob to 65 on the HSI to compensate. This post about a known HSI bug might be related? Sounds similar to me at least. :) [sIGPIC][/sIGPIC] Christmas Cheer - A Landing Practice Mission : Beta Paint Schemes : HOTAS Keyboard Map : Bingo Fuel - A DCS A-10C Movie

Scabbers Posted October 18, 2010 Posted October 18, 2010 I am going to go home tonight and play with this. The theory for ILS and tacan being merged is wrong. two completely different systems. The steering data is derived differently too. Reading the theory in the manual has left me just a little befuzzled. Now where is that speed brakes control again? [sIGPIC][/sIGPIC]

Scabbers Posted October 18, 2010 Posted October 18, 2010 on the nellis tacan. CH 12? so 012 and X or Y. Tacan is 126 channels. R and TR are matched mode and channel. Mode being X or Y. A/A and A/A TR are 63 channels apart. So one aircraft is 63 and the other is 126. Now where is that speed brakes control again? [sIGPIC][/sIGPIC]
