Cockpit textures mod for the standalone A-10A, and the Flaming Cliffs 3 module (where the aircraft is included).
Built and tested on DCS World version 1.5.8 - should also work as well with other versions (1.5.x and 2.x.x).
It is an adaptation, a conversion of sorts, from the amazing "HORSE of WAR" HD Cockpit textures pack, which Ricardo previously made and released for "DCS: A-10C Warthog". Just like before with the A-10C, these make a dramatic change (for the better) in the cockpit visuals of the A-10A, as you'll certainly realize.
