Why couldn't you mount a mini 360 degree camera on the top of the cockpit that feeds the video straight to a HUD display in the pilot's helmet? As he looks around, he sees the video feed coming from that direction. Heck, mount one to the underside of the plane too and have software stitch the video feeds into one cohesive display so the pilot could look in any direction and see his cockpit controls in front of him and the ground below him, beside him, behind him, etc. It'd be like he was flying in an invisible plane.
That'd be the way I'd solve that. But what do I know?
