O.K., in modern radar symbology, i can identify the target's closing rate, altitude, heading, and speed. However, there are these characters that are bascialy in the top center of the radar that I have no idea of what they are telling me. It consists of any variety of numerical digits accompanied by alphabetical digits, mainly either R, L, or H (don't know if there may be any otheres, those are the only three that I've seen). At first, I thought it was telling me the type and number of weapons that were on board... R = radar, L = laser, and H = heat seeking. But then I would see double digits next to them and said to myself, "they can't have 16 radar guided weapons!" So, what do these alpha numeric digits mean? I did do a search and looked in the K.B. (since I am a stickler for people to do that first) and couldn't find anything relating to what I am discussing. I've been wondering about this for many months, and honestly, I was a bit too emabarrassed to ask since I am in the Air Force, and a jet junky, and figured that out of all people, I should easily know what these symbols are. But I don't, and I really want to know. So, I guess I have to swallow my pride and ask out in the public forum on what these things are.
