New to the Harrier, but what is this on the HSI?

[Eisprinzessin]

Hi!

 

I did not find anything about this in the screenshot market "sign" "needle" or how ever you may call it.

 

Its allways the same. If i turn or not...look at the pictures. Can someone please explain to me what this means/shows?

 

 

Thanks in advance

Here you see it in the video. It jumps on the beginning ant after it stays fix...

 

i am really confused.

Its called the Ground Track Line.

 

What it exactly does though, Im not sure. But on the EHSD if you select MAPM, then you can remove it by selecting TRAX. In NATOPS they refer to it as TRAK.

If you select TRUE, the compass rose displays true heading, and now the Ground Track Line aligns with your heading.

Kinda feels to me that the Ground Tracking Line points to twice of what it actually should. On Nevada its 24 degrees off and on Caucasus its 12 degrees of your heading.

I don't know the Harrier that well either. But can it be related to True Heading / Magentic Heading? Overkill has created two very good video tutorials on the subject of TACAN for the FA-16 & F-16. The difference is again well explained here. Possibly. could that help for a better understanding.

It should show the ground track of the aircraft (hence why it "jumps" when the aircraft starts moving).

 

AFAIK it shows the "true" ground track i.e. compensating for crosswind drift, etc. effecting the aircraft.

 

In DCS it only works correctly when the EHSI is using True bearings.

 

As NATOPS uses the term "true ground track", RAZBAM appear to assume the arrow points to a particular value on the compass rose (regardless of mode), rather than graphically reflect the "true" ground path the aircraft will fly.

Shortly saying, it is a very nice tool to do ground attacks as you get very good visualization that where you are going at the current moment.

 

Sad part is that the digital moving map tile set we have is just awful to be accurately used for many things.
