I have read the manual, and searched the NATOPS for information on the HUD symbols as shown in the screen shot. I am referring to the screenshot below showing the lines in a radial pattern with AE, 49, 49 and 49 on top of the lines. They appear when Tacan is used and start bunched together at the top of the HUD when you are distant from the boat and than spread out around a circle as you get closer. Once you past the boat they move forwards the bottom of the HUD becoming a line at the bottom once you are a good distance from the boat.
I am a newbie so if this is explained somewhere, please point me to it.
Thanks for yOurhelp
