// @Description: This parameter allows you to control whether the order in which the tubes are attached to your pitot tube matters. If you set this to 0 then the top connector on the sensor needs to be the dynamic pressure. If set to 1 then the bottom connector needs to be the dynamic pressure. If set to 2 (the default) then the airspeed driver will accept either order. The reason you may wish to specify the order is it will allow your airspeed sensor to detect if the aircraft it receiving excessive pressure on the static port, which would otherwise be seen as a positive airspeed.
// @Description: Changes the pitot tube order to specify the dynamic pressure side of the sensor. Accepts either if set to 2. Accepts only one side if set to 0 or 1 and can help detect excessive pressure on the static port without indicating positive airspeed.
