jazjar Posted November 13, 2011 Posted November 13, 2011 Ok for all those with compass issues, take a look at this compass rose http://en.m.wikipedia.org/wiki/File:Windrose.svg print it out or view it on an iPhone or whatever, and look at it from an angle. Think about it literally, don't let your brain filters filter it or anything. This explains the crosses being close together and short And everything. [sIGPIC][/sIGPIC]
jeffyd123 Posted November 13, 2011 Posted November 13, 2011 OK thanks guys... i guess I get it... If the pod is looking straight ahead (like the 2nd pic in post 14) then the arrow would be mostly aligned with the planes compass. But if the pod is looking left or right, off axis of the plane, then the N arrow will be out of alignment with the plane even though the pod N arrow is pointing north, right? i7 8700K @ 4.4Ghz, 16G 3200 RAM, Nvidia 1080Ti, T16000 HOTAS, TIR5, 75" DLP Monitor
hassata Posted November 13, 2011 Posted November 13, 2011 (edited) Think of it as a huge compass sitting flat on the ground. The arrow is always pointing north irrespective of where the pod is looking. So when you get a call that friendlies are e.g. two thousand meters north of a landmark then you know a) which direction to move your eyes when looking at the TGP image and b) using the right horizontal line of the cross, how far to move them. I may be wrong, but that is how I understand it. Edit: so looking at the screenshot in the first post, 18 meters north of the end of the runway means moving your eyes in the direction of ten o'clock from the end of the runway for a distance equal to the right side of the cross, roughly.

Frostiken Posted November 13, 2011 Posted November 13, 2011 Wait, what? North? Looks to me like the arrow is pointing to the left, definitely not along that runway. It's the taxiway that appears to be north/south oriented. EDIT: Nevermind, missed Dragon saying the left/right runway. [sIGPIC][/sIGPIC]

Ok, I understood WHERE to look North, but not how far....I got some questions: 1 - Which cross are you talking about? 2 - Where is "the right horizontal line of the cross"? And why right and not letf? 3 - If JTAC gives me something like this " Vehicles on the west of the city", where is WEST on North arrow symbol? or EAST? I saw in the manual "A second line, with no arrowhead, represents East-West". There is a static line crossing the N, but always displayed horizontally. And if it doesn´t move, it doesn´t show anything, right? Where is this second line, that should change together wiht the NORTH arrow? Thx in advance
Dejjvid Posted August 20, 2012 Posted August 20, 2012 Imagine that the compass is on the floor. The arrow points to the north, and if you know the direction of north. Everything else should be self explanatory. http://en.wikipedia.org/wiki/Compass i7 8700K | GTX 1080 Ti | 32GB RAM | 500GB M.2 SSD | TIR5 w/ Trackclip Pro | TM Hotas Warthog | Saitek Pro Flight Rudder [sigpic]http://www.132virtualwing.org[/sigpic]

It´s not visible, right?So what is that horizontal line crossing the N for? And how do I know where the target is (distance)"using the right horizontal line of cross"?
FreeFall Posted August 20, 2012 Posted August 20, 2012 Ok, so East-West will be an imaginary line perpendicular to the North Arrow, right? It´s not visible, right?So what is that horizontal line crossing the N for? Horizontal line is the West-East line. It is visible. It is not perpendicular because of the perspective.
Direwolf Posted August 20, 2012 Posted August 20, 2012 Horizontal line is the West-East line. It is visible. It is not perpendicular because of the perspective. Ok, so let´s say north arrow is pointing at 2 o´clock on TGP. If I want to move TGP cursor to East ( the target is located to the East of the TGP cursor), do I move it to the right (3 o´clock) or down (5 o´clock)?

SmokeyTheLung Posted August 20, 2012 Posted August 20, 2012 Direwolf, The TGP yardstick has nothing to do with the north indication. It's the actual aiming crosshair of the Pod. One of the four distinct segments. You'll notice that as you zoom out the number to the right increases, the opposite for zooming in obviously. If my description here wasn't clear I'll explain on TS3 later tonight Rabbit System specifications: Computer, joystick, DCS world, Beer

Evil.Bonsai Posted August 21, 2012 Posted August 21, 2012 Try this at home, for those that have trouble with the tgp compass: Take two Popsicle sticks. Tie/tape them together to form a cross. On one of the tips, write the letter "N". Now, point the "N" north and lay it on the ground. Walk about 50 feet away. Using a pair of binoculars, look at your popsicle stick cross laying on the ground. Pretty much the exact same thing. :) Interesting side note: was watching the video for the SpaceX Dragon capsule re-entry, there was an exact duplicate of the tgp compass, only it was as though you were UNDER the compass, since the tracking plane was well below the capsule. As the capsule moved below the tracking plane, the compass turned into a line. It was really cool to see that and know exactly what it was!
SmokeyTheLung Posted August 21, 2012 Posted August 21, 2012 That's a great way to explain it! Especially if you try walking around and viewing it from different perspectives System specifications: Computer, joystick, DCS world, Beer
