I’ve been playing a bit more sim recently and wonder what these 2 yellow numbers mean, now I understand that the first one is altitude in meters, but the second one is not distance and idk what it could be, also if you lock the target the first one changes to something completely different, this was on the CF-188 radar if that helps

When you’re using the FCR page on any plane that uses APG-65/73/79, it gives you the information on the range of altitudes you’re searching, left is down and right is up (and it’s in thousands of feet).
3008.0ft, 7400ft
