Mirage INS Guide

[Rlaxoxo]

I've made a guide how to operate the Mirage INS (Aligning, changing waypoints, editing/creating waypoints, inputing coordinates to mark a GBU-12 drop spot etc ...)

 

First part is finished here it is:

 

Part 2

Thanks for the guide. =P

 

But how do i change the Lat long before i start Aligning (to where they correspond with real location of the aircraft)

 

You explained how to check the location but not how to change it if its not the correct one.

 

Since that is one of the main problems i have (and the reason why i cant get set up correctly to start with)

 

=P

 

I know how to start aligning etc but i dont know how input the correct coordinates to start with.

 

Edit:

I figured it out after watching the second guide =P.

 

But it would be helpful to have had that info in the start up section.

Edit: too slow :). Oh well.

 

Part 2 of Rlaxoxo's video shows inputting coordinates. If you're super impatient, skip to 2:00. For startup you modify the position of "waypoint" 0, the aircraft's current position.

 

Set the parameter knob to L/G so you get the coordinates displayed. Your PREP waypoint should be 00 - it'll start there but you can always get back to it if you've changed it by hitting PREP, 0, 0.

 

To edit the left parameter (for L/G, it's the latitude value) press either 1 or 7 on the keypad.

 

When you begin editing, the selected parameter will be blanked out (--:--.--) and both direction symbols will be displayed. So for the left side, it'll show both N (north) and S (south).

 

The 2 and 8 keys have "N" and "S" on them which should be your clue that pressing 2 will allow to input a latitude north of the equator. So, press 2 and the "S" will disappear.

 

Now you just enter the degrees north in decimal format. So for 41 degrees 36.60 minutes north, you just enter 4, 1, 3, 6, 6, 0. If you make a mistake, you can press the EFF key to start over. Once you've entered all digits correctly, press the INS key to commit it.

 

Now you've entered the latitude, you can enter the longitude value in the right side of the display. By pressing either 3 or 9.

 

For the right side, it'll show both E(ast) and W(est). You'll note again the W and the E on the 4 and 6 keys, so press 6 to enter a longitude east of the meridian.

 

Note that the longitude field is longer, as it allows for 3 digit degrees (---:--.--). On the Black Sea map you'll be between 37 and 45 degrees east, so you need to enter a leading 0 to get the required number of digits.

 

So if you're at 41 degrees 47.35 minutes east, you'll enter 0 4 1 4 7 3 5. Then press INS to confirm your input.

On second thought i cant get it working...

The manual is updated with a step-by-step procedure for INS alignment, including editing the latitude and longitude. If you just follow the procedure you can't go wrong.

Thanks for these videos man, helped a lot

[Kayos]

Thanks, good vid +1

[grunf]

Thanks for the guide! :thumbup:

Any particular step that's troubling you?

This whole thing may be a bit confusing, but once it "clicks" you realize how simple it actualy is. :D

[gavagai]

The second video is great. I don't fly a lot of CAS but you make me feel like attempting it now.

[bushido]

Thanks for the video.

 

In the second part how did you manage to move the HSI bug ? The left rotary under HSI that is supposed to do that does not work for me.

Trim keys

[gavagai]

which ones? rudder trim?

[Rlaxoxo]

Aileron to move the bug left/right

 

Elevator trim up/down to move the aircraft up down

[bushido]

When I use the trim well it trim my aircraft but does not change the HSI bug.

Turn on the autopilot.

[spiddx]

You are mistaken, that rotary is not supposed to do that. Its function is not implemented yet, so it does nothing atm. As mentioned above, use trim left/right while AP is engaged to move the heading bug.

Ok you need to trim for a long time before it move, a small imput will not work.

Thanks for the tips.

Can someone explain how I can add a new waypoint at an impromptu airfield, program in the correct values, and get a synthetic runway display?

Not sure that's possible

[gavagai]

Autopilot is on, but the trim just tries to roll the aircraft. Anything else I could be missing?

That's (probably) what it's supposed to do. The heading bug is the course the AP will follow, so if you move it (with the trim hat) then the AP will turn the aircraft to the new heading.

[EntropySG]

great guide, thanks! I start to like the Mirage more and more :)

[bushido]

Maintain the trim imput, it will eventualy move the HSI bug.

If you only give brief imput and not continuous one it will not work, I had the same issue and coulden't understand how it works at first.

[Azrayen]

The move is slow at first (one or 2 seconds) then accelerates. That allows to be precise (little moves) and quick (big changes).

So just maintain the trim hat left or right if needed :)

[Rlaxoxo]

To be fair it does feel like it's moving way to slowly ...
