Abstract: A optical assembly is utilized in various applications including in a display assembly. The optical assembly includes a first translucent substrate, a second translucent substrate, a first layer of adhesive, and a second layer of adhesive. The first layer of adhesive is bonded to the first translusive substrate and the second layer of adhesive is bonded to the second translusive substrate. The first layer of adhesive is configured for diffusive effects, and the second layer of adhesive is configured for diffusive effects.

Abstract: A turbulence data circuit for use in an aircraft. The aircraft can include a radar system configured to transmit a first radio frequency wave and receive a second radio frequency wave and a display for receiving a display signal representative of turbulence. The aircraft can further include a flight management system configured to determine a phase of flight, an aircraft inertial/air data system configured to determine an altitude and an airspeed. The turbulence data circuit can include an interface for coupling to the radar system, the display, the flight management system, and the aircraft inertial/air data system. The turbulence data circuit can be configured to determine the display signal representative of turbulence based on at least one of the phase of flight, the altitude, the airspeed and the second radio frequency wave.
