It should be in yards, I think, but it is difficult to be sure. I've certainly been working on the assumption that it is in yards. |
The PPI shows YARDS.
To convert to Nautical Miles (nm) you need to dived the range in yards with 2025 or just 2000 to make it easy.
I have found if you stop the beam right on the contact and then line the PPI up so the buttom of the station is horizontal, you can then take a pice of paper and line it up with the peak and read the more correct range from the scale. Now click on the A-scope and line that one up. Take transparent bearing tool and read the bearing off it. With out touching anything press the keyshortcut for navigationsmap - the radar operator now says the bearing to the contact so you can check that with the one you read your self.
Now plot it.
