I wasn't sure about the STOW angles so I set the PNVS to 165 inboard (0=along the nose) and TADS 180' inboard. Activated via the NVS mode switch in the cockpit (or CTRL S). The CPG station doesn't seem to have the noeswheel/NVS panel unless we missed it. You'll just have to play as the pilot if you want to flip the switch by hand.
Switch has 3 position, off (stows the sensors for transitional flight), normal for tracking head movement and fixed for boresight (straight ahead).
The NVS Mode switch is located forward of the engine power levers, left side panel.
