As I attached below, the HUD was missing from display. Up to a deeper dive, I found there is a piece of glass near the HUD equipment bay which correspond to the position where HUD screen is when stowed (pic 2). It feels like the HUD object that actually received the projection is not moving. Also I receive this message of several problems when loading .acf. I am running on X-Plane11 version, ver. 1.9, VRAM less than 6 GB. Could you look into it? Thanks!
