Currently in-game, the distance to target shown in the targeting pod uses the “Altitude” measurement unit setting as its basis for what unit of measurement to use within the targeting pod
Altitude set to ft:
Altitude set to m:
This is a strange choice and can be problematic for a number of reasons including the fact that the stat cards on the weapon systems use the “Distance” measurement unit and not altitude, which can create confusion. It would be far more ideal if the targeting pod either also used the “Distance” measurement unit or if targeting pods had their own setting within the options.
I personally prefer my alititude set to ft, but this means I have to convert on the fly ft to km before firing weapon systems such as AGMs. Managable but not ideal or easy.
