Abstract
An instrument verification system which causes the instrument needles to 'bob' periodically--a sharp momentary deflection from center. If desired, the flags can also be 'dipped' at the same time, verifying their operation as well. The pilot can easily distinguish the momentary deflection of the needles from the more gradual changes caused by deviation from true course, and is assured that the centered needles mean perfect flying and not instrument failure.
