With the F-15, what is the idea behind the range displayed in the HUD when selecting ILS not being the actual range to the field? It seems to go to an intercept point, when you get to 0.0nm it resets to airfield distance. Also, ILS HUD symbology does not appear until through this point, even though it is on the ADI.
Is this modeled in accordance with something on the real F-15, or is it the devs best guess? It doesn't work like that in other western aircraft.
