Narrative:
While in cruise flight we were in high cirrus clouds with limited visibility and little or no turbulence. We had the weather radar on; alternately scanning at the 80 mile and 40 mile scales; and had the tilt set to minus 4 degrees. We encountered approximately 5 seconds of light chop followed by an abrupt decent with moderate turbulence in what can be described as a 'downdraft'. This downdraft condition lasted approximately 10 seconds; and we lost 800 ft of altitude. We advised the ATC facility of our deviation and returned to our cleared cruise altitude of FL430.
