Airline operations today can be adversely affected by low visibility weather. When fog conditions occur, airlines are limited to certain operating minimums for landing and takeoff. Millimeter wave (MMW) radar systems are now demonstrating the ability to see in fog. Providing the pilot with a system to see through the fog may result in FAA certification to lower landing and takeoff minimums. This paper discusses the use of MMW radar technology to provide pilots with enhanced vision and enhanced situation awareness.
