Abstract: An assemblage of instruments such as in an aircraft instrument panel, either actually in an aircraft or training simulator pictured in various states of activation, are positioned behind a selectively programmed viewing device. Various individual instruments are programmed for viewing (one or more) while the remainder of the instruments are obscured behind a ported plate having partial instrument indicia on the face thereof and with the pattern of instrument ports having individual windows individually actuated by a control circuit controlling timing and sequence. This is a training aid with timing and sequence viewing improving the viewing comprehension skills of a pilot or student pilot using the training device. One embodiment is a timed and sequentially controlled system using on and off back lighting of individual instruments of a translucent aircraft instrument panel portrayal in order to enhance a users instrument viewing skills.
