Target Aspect Question: How is this 11 Degrees to the Right?

[GrEaSeLiTeNiN]

Hi,

 

I have a question on target aspect in the F-15C VSD. See attached screenshot.

 

The top left portion of the VSD shows the designated target's aspect as '11R'. I presume that means '11 degrees right'. But how is that so when the nose of the designated target appears to be pointing to the far right? I mean it would appear more like '70R'. I understand 'H' (head on) and 'T' (tail) but I just can't figure out 'R' and 'L'.

 

Would appreciate it if someone could explain this. Thanks!

11r means 110 degrees aspect angle right

 

I think the picture in this post will help you

Aspect angle is the number of degrees measured from the tail of the target to your aircraft. Aspect angle is important because it tells you how far away you are in degrees from the target's stern, which is the desired position.

Oh I see... 11R is actually 110 deg right (not 11 deg). So DCS simplified things by using DTG instead of AA?

Not clear if it's correct representation or not. Get the feeling it is not. But people are talking USAF vs. USN/USMC procedure, and not sure that means a lot on a radar screen.

 

Some radars are likely used by both and who's to say if the display is customizable without a lot more kniwledge about the ststem than I have.

 

If not they'd pick one method...

I ment to use the picture only for reference. Since that thread is 8 years old now I believe it working correctly.

 

In your picture the target is slightly off to the right and just less than 90 degree parallel, so a aspect angle of 110 degrees to the right should be correct.

 

Think of a circle drawn around the target and your aspect angle is the amount of degrees you have to go around the circle to get to the targets tail.

No, ED implemented what you would see on the real VSD in this case.

AA is off the tail.

This so far is the clearest explanation I could find...

Aspect Angle:

Aspect Angle is the number of degrees, measured from the tail of the bandit, to your aircraft. Aspect Angle indicates your relative position to the bandits 6 o’clock position. Aspect Angle has absolutely NOTHING to do with the heading of your aircraft. Your aspect angle will remain the same regardless of your Angle Off. Aspect angle is determined from the tail of the opposing aircraft. The tail, 6 o’clock position, is 0° . The nose of the Bandit is 180° . If you are on the right side of the bandit, that is right aspect. If you are on the left side, this is left aspect.

That is correct.

You also have to remember 1 degree isn't really that important in this context, that extra information isn't actually useful, so if the second digit was a single degree, 11 isn't that much more significant than 10,

 

Increments of 10's of degrees is more useful.
