Ram Air - Automation

For those that use Ram Air, one of the concerns is having it open when on the ground and bypassing the engine air cleaner thereby sucking up all the dirt and grit from the airport environment. I've determined that with the VP-200 system you could have a 4th Ray Allen servo control the Ram Air butterfly valve and then use the VP modes and rules to control when the Ram Air is on. For example, you could switch it on/off based upon a specific ground speed, or airspeed, of if you wanted you could switch it on/off at specific altitudes, or maybe even times of flight, etc. Within reason, the possibilities are endless. In my case, it only took using the 2nd servo control function on the second CU in a VP-200 system.
