Is it possible?Not with dedicated instrument. But you just need to manouver to have the arrow pointing the opposite of the desired course, and steer towards the waypoint.

Ramsay Posted May 8, 2020 Posted May 8, 2020 I usually set a course for runway orientation from a tacan beacon to intercept. Can't see how to do this in the Mirage. Is it possible? Not as far as I know. Normally I'll aim to intercept the runway azimuth @45° (DME approx 10-12 Nm) and make my turn to final just before the TACAN needle aligns with the runway heading on the HSI. I'll then fly an ILS or TACAN approach as necessary. Both Razbam's and Chuck's guides describe using VAD (TACAN offset), which can setup a navigation point to align with an approach but I've never made use of it outside of training missions. In real life, runway direction may be entered on the PCN for the synthetic runway/landing waypoint but it isn't modelled in DCS. AFAIK there isn't a CDI (Course Deviation Indicator) for the radial, etc. i9 9900K @4.8GHz, 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 11 Pro x64, Odyssey G93SC 5120X1440
imacken Posted May 8, 2020 Author Posted May 8, 2020 I can see how VAD could be useful, but that would mean calculating a point along the azimuth of the runway which could be messy. In any other jet I can think of, I just put in TACAN info, define a course as per the runway heading, intercept the line and head on in.

Britchot Posted May 8, 2020 Posted May 8, 2020 (edited) Setting an offset from the TACAN along your landing runway's back azimuth at a distance of 10-12 nautical miles would not be messy, at all. Plus, just turn to TAC and the needle will point towards the TACAN for you to follow in to the runway. Or, if you have a VOR on the same runway, you have the thin needle.

TaleSpin Posted May 9, 2020 Posted May 9, 2020 (edited) I usually set a course for runway orientation from a tacan beacon to intercept. Can't see how to do this in the Mirage. Is it possible? Since the Mirage "only" has (a type of) RMI (radio magnetic indicator) you would have to "memorize" the course to intercept; then flying the intercept procedure and watch the needle turn towards the desired track. Then turn in towards this track and keep the needle there. Not easy without wind, quite tough with :) Just treat the TACAN approach like an ADF approach (you're familiar with that?). Maybe this graphic can clarify what I mean: https://www.aopa.org/-/media/Images/AOPA-Main/News-and-Media/Publications/Pilot-Magazine/2018/1803/1803p_pe_oninstruments1/1803p_pe_oninstruments1_16x9.jpg?h=675&w=1200&la=en&hash=492A0D96B964D21459C716CCE507CCB9 EDIT: And yes, there is the INS option.

Sorry, I didn't mean that setting the VAD offset would be messy. It is the fact that offset is a point, not a line, that could end up being messy compared to a course line that can be intercepted anywhere along its length.

imacken Posted May 9, 2020 Author Posted May 9, 2020 Guys, thank you all for your help. I was asking if a course line could be set in the Mirage, and I think the answer is no!

TaleSpin Posted May 9, 2020 Posted May 9, 2020 ...and I think the answer is no! I am not sure if this conclusion is correct :unsure: It is not possible with TACAN, yes, but IIRC the INS training mission stated a method that does exactly what you want - creating a "line" (track xxx°) to guide you in. This of course requires a waypoint "on the airfield" as destination, so if you don't want to program this one (either on ground or during the flight) then yes, the answer is most likely no :book:
imacken Posted May 9, 2020 Author Posted May 9, 2020 Guys, again, thanks for all your comments. I think the thing is, that there are a few ways of achieving this in the Mirage, but there is no course setting available. All other methods are more involved. But, at least my question has been answered.

=36=Witcher Posted May 12, 2020 Posted May 12, 2020 (edited) Thanks for that. Could you expand on that a little as I don't really get what you mean? Sorry, I forgot to check for replies in this thread. To answer your question: no, there's no "Course" selection in the Mirage HSI. You only have an arrow pointing to your destination (it may be a waypoint, an offset from the waypoint, a TACAN or an offset to the TACAN according to your HSI and INS settings). What I suggested is the method I use to intercept a course in the Mirage. Let's say I am 10nm west of my waypoint: my HSI will show an arrow pointing east, so towards 090; the back of the arrow will of course point the opposite, 270. In other word, I am on radial 270 of the waypoint. Now, I want to reach the waypoint from the radial of, let's say, 300. Of course I have to point north to intercept radial 300. How do I know I am on the correct radial? I will be when the back of the arrow will be at 300. As soon as it will be, I will turn to heading 120 (opposite of 300) and I'll reach the waypoint on the desired course. After all, if you look at it, despite being "fat", the HSI arrow has a thin line at the end, that serves exactly this purpose: know exactly on which radial you are related to your current destination.
