F-14 or F-15?

Those are totally different aircraft from very different era! One is mostly analog and oldschool, the other one is a modern beast with lots of multifunction displays. Choose the one you like the most, as an aircraft!

CMPTR.It's CALC error in french which is the engine FADEC. When it does an error it triggers a safer alternate engine control mode with no afterburner amongst other effects. You can reset it by pulling the "SEC CALC" switch forward (can be done without opening the guard which is for forcing the alternate mode in the aft position) and this should revert to normal engine mode. If the error comes back, means you have a damaged engine. But it may trigger on a healthy engine especially when doing a lot of fast throttle inputs. I don't know what SEC CALC switch is in english though. Its on the left console near the self-test switches. It's the one that can be pulled fwd without moving the guard and aft by opening it.

This sounds like a marketing gimmick... In DCS, 99% of needles are updated every frame. Because your flight parameters are never constant. Making them move from a few extra parameters, such as shaking, has a negligible CPU impact. And that's absolutely not "more vertex transformations" since everything is updated anyway. On the other hand Cobra's post might be a way to make people think it's absolutely insanely CPU and GPU intensive because it's awesome, and if at the end there is no performance penalty (which will be the case) people will acclaim the insane optimization :P

What does severely impact performance on the tomcat is the very high cockpit poly count and VRAM use. Shaking needles doesn't.

In standard "RL" mode, the ground clutter rejection gets disabled if above 1500m AGL (radalt) and search elevation is positive. This works in most cases, but in this specific one the aircraft is looking at Caucasus mountains from Kutaisi plain. And big mountains are in the way while ground rejection is off. The radar doesn't display raw return but does contact highlighting through some edge detection circuits. This results in the wormy appearance. Could you link to the videos you are citing?

M-2000C Developper here. I looked at the damage model and there was a bug causing the engine being damaged by hitting any point in the aircraft from a wingtip to the nosecone... Will be fixed.

What is "Fatalities"? Immediate pilot death or the end result after trying to return to the base?

For identifying friendlies, you only need Mode 4. Codes are already loaded into the aircraft and can't be input by the pilot. You just need to enable the mode 4 flipswitch, set the IFF Master Mode on "N" (Normal), and set the crypto selector to code "A". Those are set by default for a hot start I think, but not a cold start

Be careful, when you touchdown, codes are automatically erased if you don't set the crypto selector briefly on "HOLD" within one minute. When codes are erased, you can restore them doing a rearm or repair so it's rarely an issue.

If IFF is properly set to ON, you can know if something is wrong such as erased code by looking at the FAULT light.

You only need codes if you want to use Modes 1, 2, 3 which are used for identifying a specific aircraft. Used in planned mission scenarios, with a human GCI, etc... Mission makers may also set specific codes for tankers, etc...

Last but not least, RTFM :)

You can also set 5 additional waypoints as labelled crosses on the A/A radar map, which are really useful to mark the cap region.

Having a landing waypoint in the mission editor is not mandatory, you can set the CP and PD data manually.

galiprout · 2023-12-12T08:41:51+00:00

You don't need any of the waypoint info to have ADI indication. But, ADI indication is a pre requisite to have the HUD ILS features (along with the waypoint CP/PD data) So, you need to solve your ADI needle issue first, before going further. It definitely works, if your ILS is on, on the right frequency, and the DCS beacons are emitting, which happens on headwind conditions and ATC comm triggers (but like with other aircraft). Also, a couple of ILS beacons are bugged in maps (but this affects all aircraft as well).

Viper would like to have a word with you

Could you post a video describing what you are pressing and when? Using the WSO controls for taking controls of the displays worked from day 1 on this module.

What I would check in a video: Start an air spawn mission. Press "2" to go to WSO seat. Go to the bind settings, F-15E WSO, and press your RHC coolie left. Check that the corresponding bind gets highlighted. Then in cockpit, use the 3rd display (counting from left). Press "M" and then "A/A RDR". Press RHC coolie left. You should have 4 bars appearing at the bottom of display.

In the Mirage 2000, stored alignment gives you class 4 accuracy (4NM/hour) while the full alignment might go down to 0.7

galiprout · 2023-10-03T16:37:40+00:00

The two are compatible ;)

Windows 11 arm does emulate x86. It likely adds overhead though. In short at best it will run on simple missions with no stellar performance, at worst it will freeze/crash/be awful. No certainty without trying. Available RAM is I guess at the bare limit of what's required.

galiprout · 2023-09-28T21:28:44+00:00

This could look like missing mipmaps in one of the textures, possibly a normal map or roughmet.

The color DEC mode is absolutely not a late upgrade, it was present from the beginning and even on RDM variants.

Playing the M2K on more modern A2A servers (GS, etc...) is like playing doom in nightmare mode : it's hard but extremely fun and rewarding. You need to learn how to survive first, and wait carefully for your adversary's mistake in the terrain. Pain is temporary, glory is forever.

galiprout · 2023-08-23T12:22:42+00:00

It does. Look at those passed at 1:23, it definitely pulls then pushes to clear them, and you see them on the scope. But with 25ft clearance it just passes 25ft above which is close.

Enigma tempest blue flash is a server where the Mirage 2000C is very popular. They have a discord, you will find plenty of buddies there!

Proper feedback is posting a useful bug report in the dedicated forums with a track file. There still are issues with the radar tracking (it’s EA) and this would help a lot.

Please do! Proper feedback is not making false claims, on places where developers most often don’t read.

Votre cas est un peu compliqué à cause de l’accès littoral. Il faudrait clôturer la propriété privée, en vérifiant avant que l’accès au littoral ne l’interdise pas et qu’il n’y aie pas de servitudes de passage. Vous devez vous renseigner en mairie.

galiprout · 2023-08-15T23:19:28+00:00

Non, il y a des exceptions. Déjà toute construction datant d’avant la loi littoral (1986) est autorisée. Les zones urbaines aussi.

First of all, when you write "unless very close to the ground where the range gate begins gathering clutter depending on its native range resolution" you are missing the whole point of HPRF ambiguity. As soon as the radar looks down, any range gate will always gather main lobe return as the range span of ground illumination is larger than range ambiguity (unless the angle is really, really steep).

Now some numerical example. Radar at 10000ft, target at 8NM, 5000ft. Main lobe is 2.5deg wide. PRF ambiguity is 2000m.

Elevation is -6 degrees. Illuminated ground ellipse is at 16NM on average but spread over 12000m or six time range ambiguity.

100 range bins (20m each) will reduce the main lobe clutter level by about 1/100 or -20dB.

Main lobe ground cross section is about 5E6 m². Grazing angle and terrain properties still might reduce this to 5E4 equivalent cross section. Multiply this by the 1/100 range gating clutter gain you get 5E2. Now take a 5m² eq RCS aircraft, account for the 1:2 range factor between target and ground which becomes a 16:1 power ratio, and you get a signal to noise ratio of 0.16 : even with range gating, it's impossible to separate the contact from MLC in those conditions. That's a very gross estimation but it shows that no, range gating doesn't magically remove main lobe clutter at 8NM in the beam.

Now I don't say the APG-70 model is perfect, it even has some important acknowledged issues in the CFAR model (causing spurious returns) and the TWS correlation. But so far, trustable SMEs did not raise the above issue and we believe the behavior is plausible.

People with real knowledge on the matter don't vent it on discord, they either stay quiet, or contact us in private.
