This paper presents the improvements integrated into the second generation of Enhanced Vision System (EVS) or the Enhanced Flight Vision System (EFVS) (in comparison with the first generation). These improvements are based on the experience and knowledge accumulated during the last 3.5 years of observing more than 300 planes operating with the EVS system. Among the main improvements incorporated into the second-generation product are: - Higher probability of detection for runway lights and flashers, during bad atmospheric conditions. - Extended algorithm for ambient temperature compensation, eliminating the requirement for optics and dewar head temperature stabilization. - The sealed-off system that constitutes the second generation, not requiring any air flow supply or temperature stabilization. (The EVS first generation requires an air flow of 7 liters/second at 23° C with a relative humidity not higher than 30%. The airflow prevents water condensation on the optical parts and also enables stabilizing the optics and dewar head temperatures.) - Improved algorithm for the replacement of clusters of bad pixels. - Reduced size, weight, and power consumption.
