the training sights are on in the training arena up a buff or a jabo with eggs in the fighter you must select the bombs you will see a green x below the plane this is your ccip make your dive put x on target and release. allso works with rockets cept the x will appear right in front of you instead of below but only after you have selected your rockets and or bombs. buffs will see the green x all the time when bombs are loaded.
acording to another post I read if you have calibrated your level bombsight correctly the green x will converge with crosshairs when over target.
as far as using them offline I havent tried that but they work in training arena.
