length and heading associated with waypoint?

[Snakeice]

Hi, I saw this feature in the changelog: 

• NEW: Added ability to enter length and heading associated with waypoints on TID. 

Whats the use of thsi function? Are there any tutorial/references? 

Thanks!

It was used, for example, to highlight ground features (handy for coasts, for example). It is a simple way to provide more SA since we do not have a moving map.

 

I have not used it yet, but I guess it can be handy for tight IP→TGT. Perhaps highlighting the axis around the Echo point when practising and training CAS? Or even part of the FLOT if relevant?

It's for marking stuff on the TID
You can mark shorelines, orbits, flight paths, runways, and really anything you can think of

As for how to use it, you'll have to select a waypoint (either thru CAP panel or hooking it on the TID), and then on the TID panel use the speed button (i think it's nr.3) to change the length of the vector, and the heading (or bearing) button to adjust it's angle from 0 to 360 degrees

Note: I don't remember exactly which button adjusts the direction of the line, but it's one of the two mentioned above
The other one changes the position of the waypoint, taking the heading you intput it, and placing it on the designated distance on that bearing from your plane

Note 2: Don't use the range pushbutton (nr5). That will change the position of the waypoint in relation to your plane. It will put it on the same bearing, but change the distance to the waypoint

Disclaimer: These conclusions are just me messing around with this for some 10 min, so take it with a grain of salt and experiment a bit
Cheers

It would make sense, it's SPD and HDG of a WP, so I guess it's just a matter of hooking/selecting the WP, selecting SPD or HDG and enter the values. Something similar to how the NAVGRID works.

Don't use BRG though, it will move the WP to that bearing (not the ATA).

 

I applaud your artistic skills, @BonerCat :D

BIO used it for example during Earnest Will to depict the Iranian coast line, etc... It helps to stay out of no fly zones, and so on and so forth. Basically you can draw limits or borders (for whatever reason) on your "map" (TID). Or, as demonstrated, it can serve to unleash your endless creativity upon the world... Although I am not sure why he chose to draw mittens, I mean those Bernie memes are getting out of hand for sure!

Hmmm ... can I use it from the front seat (via Jester) to draw a line through a waypoint (or bullseye) on a given bearing??

No, we might add that at a later point.

[Kula66]

Ok, thanks IM, that would be really useful.

It seems like the length of the vector seems to be capped around 3000? or so SPD. Is that a limitation on the real 14?

Might be related to the updated TID: "Fixed max length of all TID vectors from 1.35" to 1.5" "

[BonerCat]

I think it's capped to roughly 4000 (or something around that)
I think that's because (again, this is a guess) it's the highest closure speed that the AWG-9 can still detect a target, therefore, there's no reason to draw a vector longer than that
Something worth noting, is: since you're adjusting speed, not length of the vector, it'll always take up the same amount of space on the TID, regardless of the scale the TID is currently in
Therefore, the further you zoom out, the longer (in miles) the vector would be when overlaid on the map, but keep it's length on the TID
A max speed vector will always be 1.5'', regardless of the TID scale

Thanks Guys for all your info! So we can tecnically use it to make a route between waypoint right? There is a relation between SPD import and lenght in nautical miles of the segment?

Thanks to All!

No, it's just a speed vector and does not represent any lenght in nm, especially when it does not change its lenght in different TID scales. Read again BonerCat's post. So, depending on the scale and distances it can be connected as a route between waypoints (say it was done at 100nm TID range), it will have gaps in 50nm range, and twice overdrawn in 200nm scale.

so i think i've absolutely misunderstood everyting. good. What exactly is a speed vector?. IronMike told that it was used to drow borders, but if the dimension doesn't change with the TID range, i can't have a correct information right? ( probably i'm 1000% wrong, in case,please tell me!)

Thanks

Speed vector is just the line on the TID that represent the direction of move of the target, which shows its lenght as the speed (longer is faster) and heading (depending on the TID mode, related to ground or your aircraft). Using it for waypoints is just a creative way done by RIOs, it was not designed for that in the first place. Drawing borders or CAP lines was used just as reference for SA, not as a precise drawing tool. You can use it and it will be correct information but you have to know its limitations.

ah ok, make sense. i haven't understood the purpose of the speed vector of a fixed point (speed 0, no vector lenght) but now it's clear. 

Another question: in the first bonercat's post at note two, he told that we mustn't use RNG button as it change range from our position to waypoint. so i suppose that i can add a waypoiint if i know Bearing from my position and distance? 

Thanks!

If you input the range and bearing to the waypoint, then yes, you can change a position of a waypoint
It probably won't be very accurate if you're moving tho, unless flying straight towards that point
