Opportunities to Improve the Safety and Security of Airport Surface Movements at Airports Due to the WAAS Implementation

Dejan M. Damjanovic

Abstract:	Air Transportation must consider the safety of operations on the surface of an airport (known as Surface Movements) as an integral portion of the entire life cycle of a flight. Significant accidents include massive loss of life have focused the attention of the aviation community towards the development of tools and techniques to reduce ground accidents. While the technology of moving maps have been available to aid in enroute and terminal navigation, the use of this technology has lagged behind, due to a lack of the appropriate components or enabling technology needed to supply a complete solution. With the implementation of the WAAS and eventual LAAS systems to augment raw GPS, we can now look at the full implementation of navigation systems that can support low-visibility or zero-visibility taxiing operations on the surface of an airport. The paper will discuss a number of the other enabling technology that allow new Operational Concepts to be implemented, to significantly increase the safety and security for aircraft to conduct surface movements in low visibility or zero visibility conditions. A significant extension to this capability is the integration of ground vehicle position monitoring onto the surface of the airport in the areas that support aircraft operations (known as the Movement Areas). This would include runways, taxiways, aprons, ramps and parking positions. Those areas that do not support actual aircraft operations are known as Non- Movement Areas, and they include buildings, parking lots, and maintenance facilities for ground vehicles.
