Benefits and Possibilities

The benefits of SVS are evident for pilots; it provides the pilot with a dynamic perception of position, trend, and motion. In addition, the vision system lowers mental workloads, enhances visualization in low-visibility conditions, reduces flight technical error, and improves the ability to detect and avoid Controlled Flight Into Terrain (CFIT) situations, where a piloted aircraft is inadvertently flown into the ground, mountain, water, or other obstacle.

In the future, other SVS possibilities exist, such as lower landing minimums. A pilot’s landing minimum determines an appropriate altitude for an aircraft’s approach, based on factors such as weather and visibility.

Established in 2006, RTCA Special Committee 213 (SC-213), an international collaborative effort of government and industry, creates consensus requirements for SVS and Enhanced Flight Vision Systems (EFVS). The group is currently developing Minimum Aviation System Performance Standards (MASPS)-level guidance for SVS, Enhanced Vision Systems (EVS), Combined Vision Systems, and EFVS. RTCA SC-213 Synthetic Vision Guidance System (SVGS) MASPS is expected to be released in upcoming months, and will capture SVGS operational credit requirements for a lower minimum of 150 feet height above touchdown. The system will be used during published Instrument Approach Procedures (IAP) with operational minima that are less than the minima for current Category-I landings. Lower minimums could increase landings under a range of weather conditions.
