Determining the depth of a contact

[Henson]

Modern TMA makes a few assumptions about the battlespace, one of them being that both contacts are at the same depth. It makes the math a LOT easier, and is just as accurate from a purely TMA standpoint (though choosing search and evasion depths is something else entirely).

Don't worry about depth. If an ADCAP gains a track it'll feed depth back to you IRL.
