Zeus67 Posted August 24, 2016 Share Posted August 24, 2016 In a couple of posts up I mentioned the erratic behavior of the ILS HUD localiser line and anchor point. This video is of an A319 ILS approach. It clearly shows the logic of how the Localiser HUD line and its anchor point should behave in the MIIR2K HUD. The A319 HUD has both the Synthetic runway ILS localiser line and the ILS Anchor point. It differs in that the Pitch ladder is caged to the centre of the HUD rather than the velocity vector To get to the main ILS HUD video start at 9:54. This is a turn to intercept the localiser. Thanks for the video. "Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots.

SCU Posted August 30, 2016 Author Share Posted August 30, 2016 The FPM didn't get linked to the pitch ladder with weight on wheels/on the ground, can you fix that when you have time?

SCU Posted September 11, 2016 Author Share Posted September 11, 2016 To be honest, we took care of a handful of HUD issues but I think there is still work to be done, if you seen anything in this latest updates, please let me know so we can get them figured out. The FPM and pitch ladder are so close to being accurate to reality, but it still needs some fine tuning. The lower limits of the FPM in 'normal' Nav mode should be lower down in DCS, it's too shallow at the moment. While in 'app' mode the opposite is true; it's slightly deeper (lower) than reality. I suggest that you work on normal mode FPM limits first and then match 'app' mode to it. It's easy to figure out precisely where on the HUD the FPM limit is by watching the video & comparing the pitch ladder's numbers to the Magics' G & D indications while in a 90 degrees bank angle. Because the Magic missile indicator are in a fixed position, we can get an accurate modeling of the FPM in the sim assuming the G-D are correctly positioned (<--they seem fairly accurate to me).

Should be the same for Approach mode as far as I know. Note: the upper limit needs to be slightly higher than it is now, just a tad more above the heading tape.

Thank you SCU, greatly appreciated :) "Witness mere F-14s taking off from adjacent flight decks, gracefully canting left and right, afterburners flaming, and there’s something that sweeps you away—or at least it does me. And no amount of knowledge of the potential abuses of carrier task forces can affect the depth of that feeling. It simply speaks to another part of me. It doesn’t want recriminations or politics.

SCU Posted September 12, 2016 Author Share Posted September 12, 2016 Thank you SCU, greatly appreciated :) Thank you! :thumbup: Please can you also look at the FPM not being linked to the Pitch Ladder while on the ground (Weight on Wheels).

IvanK Posted September 17, 2016 Share Posted September 17, 2016 I also think that the "fly-to" direction in the ILS glideslope "box" is reversed in the horizontal. I can confirm Catseye's observation. The Localiser Arrows on the ILS Flight Director HUD box are reversed. Should be as in the inset , See below: Steering cues to Glideslope are correct.

I've reported it a couple of times and the last I heard from Zeus was that he would look at it later when he started to work more on the ILS system. This was several months ago. Hopefully, this is in his upper file folder now. :) Cheers, Link to comment Share on other sites More sharing options...

Thanks for the video. Is there an update on attaching the localizer HUD line to the synthetic runway/anchor point so it is 'ground stabilised' and doesn't swing about due to roll, etc. i9 9900K @4.7GHz, 64GB DDR4, RTX4070 12GB, 1+2TB NVMe, 6+4TB HD, 4+1TB SSD, Winwing Orion 2 F-15EX Throttle + F-16EX Stick, TPR Pedals, TIR5, Win 10 Pro x64, 1920X1080 Link to comment Share on other sites More sharing options...
Azrayen Posted July 1, 2017 Share Posted July 1, 2017 (edited) Agreed, Ramsay. The localizer HUD line should be attached to Runway position (not to the synthetic runway itself, because you may have the line displayed without the synthetic runway, IIRC - will check). What's needed to display correctly the loc line: - Current Wpt (should be the runway position) - CP parameter (runway heading); As you may know, CP (and PD) parameters of the INS are not active at the moment (but the runway heading can be known if there is a "landing" waypoint set in the ME). - Aircraft current position & heading, of course. Perhaps an update should look at that too (or first), to be able to display correctly the Loc line. Edited July 1, 2017 by Azrayen Link to comment Share on other sites More sharing options...

Hi everyone. This didnt get fixed, right? Cause the closed box still behaves wrong during ILS approaches. The video clearly shows how the FPM is centered on the box based on roll and pitch like an FD. 1 Intel Core i5-8600k + Cooler Master Hyper 212 EVO | Gigabyte GTX 1070 Aorus 8G | 32GB DDR4 Corsair Vengance LPX Black 3200MHz | Gigabyte Z370 Aorus Gaming 3 | WD Black SN750 NVMe 500GB | Samsung 850 EVO 250GB | WD Green 240GB | WD Caviar Black 1TB SATA 3 | WD Caviar Blue 500GB SATA 3 | EVGA 650 GQ 80+ Gold | Samsung CF391 Curved 32" | Corsair 400C | Steelseries Arctis 5 --- Razer Kraken X Lite | Logitech G305 | Redragon Dyaus 2 K509 | Xbox 360 | Saitek X-52 Pro | Thrustmaster TWCS | TrackIR 5 Link to comment Share on other sites More sharing options...
rrohde Posted February 21, 2020 Share Posted February 21, 2020 @Ramsay: If that would get fixed as you suggested, the whole ILS approach concept would make a lot more sense in the M2000.

StrikeTrigger Posted February 21, 2020 Share Posted February 21, 2020 I just went towards the TACAN selected heading at very low speed and got into within 10 nm, after which I checked out runway shape and then maneuvered to visually line up with the runway heading, hoping I'm not taking the 180 degrees opposite heading XD Later on I just started checking the Caucasus aerodrome chart to figure out the right heading for my runway.
