Instrument Inoperative Cover
The instrument cover is a plastic disk approximately 2 3/4” in diameter and 1/16” thick. By use of the attached suction cup, the cover will mask the face of most general aviation flight instruments. It is useful in many training situations one of which is partial panel work. As a safety aid, the cover can be used to mask an instrument when it is non-functional, as is required by Regulations. Each package has two covers.
