The INSCO 2202-1002 Rotor Speed Warning Unit was developed as a
rugged, dependable replacement for the existing overspeed warning
unit for the MBB BO-105. Employing totally solid state circuitry,
the unit provides crisp, precise switching for both aural and visual
warnings.
The unit mounts without modification to the aircraft structure or
wiring, and is housed in a heavy anodized aluminum case.
The 2202-1002 is STC approved for use on the BO-105.
