Sensory-Spatial Conflict and Control Reversal Error (Patterson et al findings)
Control reversal error during IMC “out” to “in” visual transition.
References on reversal errors:
Patterson, et al, 1997
Braithwaite,et al, 1998
Gallimore, et al., (1999)
Liggett & Gallimore (in press)
9 errors out of 24
8 errors out of 24
6 errors out of 24
What happens during the transition from visual to instruments?
1. Recognition of pilot spatial awareness strategies (Patterson et al findings)
3. Avoidance and recognition
of Visual Illusions (perspective illusion)
2. Avoidance and recognition
of spatial disorientation
(VMC-IMC form/ reversal error)
4. Design of flightdeck displays
