Checking if others experience the same issues: Air air TACAN + radar back to SIL issue? + decol light

[Leviathan667]

Hi all, do you experience the following issues with the Mirage?

1. I seem to have an issue with AA TACAN (it simply does not work) while ground (T/R) TACAN works fine
2. Radar when I go back to EM a 2nd time after having switched to SIL after having been on EM a 1st time
3. The BIT for the FBW system most of the time fails - I have to start over the testing 3 - 4 times before it succeeds (decol light will remain lit until such time comes when the test has been passed successfully - green light)
4. Decol lights up again on the warning panel after having landed even when the BIT for the FBW system has succeeded prior to take-off.

1. I have AA Tacan issues with most DCS modules, AFAIK it's a DCS core issue and we need to wait for ED to fix it.

2. Radar SIL not something I usually do, so it might be worth adding a short track and elaborate on your issue.

3. Is this despite having done a couple of control "wipes" first to warm up the Hyd fluid and remove any trapped air in the system ?

4. After landing (weight on wheels) the aircraft is out of trim for takeoff (hence the Decol warning), pressing the Autopilot Standby Mode (AP Disconnect) switch on the stick will reset the trim and cancel the warning lamp and alarm. If like me, you don't have a spare button on your stick for AP Disconnect, toggling the autopilot [A] will achieve the same result.

This Decol behaviour after landing is normal, are you new to the Mirage or has the behaviour changed in someway ? Might need a track or further explanation from you if it has ?

User above explained the FBW test — you have to sweep the controls before you run it.

 

I regularly use A/A TACAN mode and it works with my wingman giving yardstick distance (you are not supposed to get bearing) when the IDN is set to tac mode. If you’re trying to use it to find tankers then ones in DCS need to (incorrectly) use T/R mode I think. The TACAN implementation for the tankers is a bit messed up in DCS in general. The KC135s are not supposed to give bearing at all.

I also regularly toggle between SIL and EM mode for the radar with no problems. What exactly is the issue you’re running into with this one?

I also frequently toggle the radar between different modes in my flight, but don't have any issue on it.  Maybe save a track next time so we can understand the problem.

 

Some small addition for the DECOL warning,you can double press the Autopilot Standby Mode button after you have touched down on main landing gear but before the nose gear have dropped on the ground.

In this way the DECOL warning will never come up on landing.

ED broke A/A TACAN in the whole game, and the worst part is that they believe its [correct as is] i think it works only with human-controlled planes now.

Thank you all for your replies.

 

Following your advice, the Decol issue has been solved for me. In a way I am new to the Mirage as I flew it a month of so in 2018 then went on to other modules until I came back to it a few weeks ago.

I understand AA TACAN is incorrectly implemented. Finding the tanker works with it in TR mode.

For the radar EM to SIL then back to EM behaviour: call it Murphy's law (or the opposite) but since I posted my message, I haven't been able to experience it anymore while I remember I consistently did before.

If it happens again I'll make sure to save the trk file

The current M-2000C is like a new aircraft compared to the version released in 2018 with many improvements and refinements made with the help of the AdA i.e. most youtube guides more than 12 months old are more or less out of date.
