admin I may have a possible fix for the lighting issue on Android devices where the lights of the aircraft do not illuminate the ground. The main issue is the Vulkan rendering engine for android which is causing the lighting shader incompatibility. So instead of shader based lighting, IPACS can implement texture based lighting (A lightmap) for android devices. GTA San Andreas also uses this method of lighting the ground by car headlights.
Example image is given in the attached file.
