> Adding computer redundancy won't fix single sensor screw up. Will they retrofit all planes with dual sensors? There are already two sensors. There are also already two computers. Each computer is already connected to one (and only one) of the sensors. Therefore, making the software use both computers at the same time allows using both sensors at the same time, with no hardware changes.
