The aircraft cockpits are 3D model programs with indexed instrument textures. The original virtual cockpit uses static mock MFD artwork on its screen faces; the faithful preview retains it. This inspection camera sits inside the cockpit. The bitmap overlays below are captures of original x86 drawing programs, with their exact pixel coverage masks.
Artwork loaded by the native HUD initialiser. All frames are shown below. The optional capture layer uses native placement with supplied telemetry; a complete live flight HUD is not simulated.
