1.   Loss of spatial orientation is a serious problem for pilots.

2.   She suggested games like chess or jigsaw puzzles to foster spatial orientation.

3.   The indicator, which displays an artificial horizon, is used by pilots to maintain their spatial orientation when they cannot see the horizon out of the windows.

4.   Inertial reference systems, which calculate the precise position and spatial orientation of aircraft and nearby objects, are key components of aircraft navigation systems.

5.   This essentially made the game an incredible experience in spatial orientation.
