Title:
FLIGHT TRAINING HOOD
Document Type and Number:
Japanese Patent JPS52103232
Kind Code:
A
Abstract:
Instrument flight training glasses including a voltage-controlled, liquid crystal viewing lens system operable to a first state of transparency when wearer is viewing the instrument control panel of his aircraft and operable to a second state of opacity to instantaneously occlude viewing when wearer changes his line of vision outside of the aircraft. A lens position sensing system monitors the relative position of the lens system with respect to the aircraft windshield for lens state actuation responsive to a lens position permitting the wearer to view through the windshield along his greatest, upper peripheral line of sight. A manual switching arrangement permits maintenance of lens transparency to provide vertigo simulation capabilities upon flight landing approach whereby wearer changing his line of sight outside of the aircraft to occlude his viewing, and thereafter manually switching the lens to its transparent state enters a condition of vertigo.
