- Digital Terrain System: Completely missing including its subsystems like PGCAS, TRN, OW/C, DBTC & PR. An essential system from the earliest tapes of the F-16CM-50 where you load the terrain data of a 480x480 nautical mile area wherein the DTS has features both to avoid CFIT (controlled flight into terrain) which was the biggest cause of death in the USAF at the time, to providing various subsystems to facilitate safer low altitude operations including a kind of digital "terrain following radar" mode, to decreasing INS drift by comparing your radar altitude to the know terrain elevation in different parts of the map, and also to allow more accurate targeting without using active sensors. This is for example what makes high angle JHMCS markpoints accurate, as it can reference the known ground elevation of the location you're looking at. Without the Digital Terrain System implementation, the DCS F-16C has much higher risk of CFIT, much higher risk of flying into terrain/obstacles during low altitude operations, much lower targeting accuracy (especially at longer ranges and in uneven terrain), and higher INS drift over non-flat terrain than a real F-16C of our block and tape would.

This is locked as I investigate.
