A convenient quick on/off “Angle of Attack” (AOA) vane protective cover. This cover uses two mechanical suction cups to secure it to the area around the AOA vane. These high-quality suction cups eliminate the possibility of the cover becoming misaligned or falling off. It does not attach directly to the vane or put any pressure on it, but provides comprehensive protection from fluids and physical damage. These covers are effective in a temperature range from -15F to +120F for extended periods of time. Our covers are made of high-quality aircraft grade aluminum allow and are coated with a resistant bright red coating. We include self-stowing streamers for high visibility and added safety.
