    (1)     fully functioning dual controls are installed in the aircraft3; and


    (2)     an additional qualified pilot ('a safety pilot') occupies a control seat to act as safety pilot for the person who is flying under simulated instrument conditions; the safety pilot must have adequate vision forward and to each side of the aircraft, or a competent observer in communication with the safety pilot must occupy a position in the aircraft from which the observer's field of vision adequately supplements that of the safety pilot
