NASA's Synthetic Vision Systems (SVS) project is developing technologies with practical applications to eliminate low visibility conditions as a causal factor to civil aircraft accidents while replicating the operational benefits of clear day flight operations, regardless of the actual outside visibility condition. A major thrust of the SVS project involves the development/demonstration of affordable, certifiable display configurations that provide intuitive out-the-window terrain and obstacle information with advanced pathway guidance for transport aircraft. The SVS concept being developed at NASA encompasses the integration of tactical and strategic Synthetic Vision Display Concepts (SVDC) with Runway Incursion Prevention System (RIPS) alerting and display concepts, real-time terrain database integrity monitoring equipment (DIME), and Enhanced Vision Systems (EVS) and/or improved Weather Radar for real-time object detection and database integrity monitoring.A flight test evaluation was jointly conducted (in July and August 2004) by NASA Langley Research Center and an industry partner team under NASA's Aviation Safety and Security, Synthetic Vision System project. A Gulfstream G-V aircraft was flown over a 3-week period in the Reno/Tahoe International Airport (NV) local area and an additional 3-week period in the Wallops Flight Facility (VA) local area to evaluate integrated Synthetic Vision System concepts. The enabling technologies (RIPS, EVS and DIME) were integrated into the larger SVS concept design. This paper presents experimental methods and the high level results of this flight test.

“…In many cases the image will be so compelling that the pilot will be slow to detect a problem with the terrain database, so other integrity checks are needed. NASA and others have evaluated a number of integrity monitoring schemes 6,7,8,9 and reported that the detection and warnings are effective.…”

Displaying video on a head-up display from an Enhanced Vision System camera or Synthetic Vision System engine presents some unique challenges not seen on conventional head-down flight deck displays. All information displayed on the HUD has to be seen against a background that can vary from bright sunlight to a dark night sky. The video has to include enough grayshade information to support visual identification of runway features and the image shown on the HUD has to be visually aligned to the real world accurately enough to support low-visibility operations at airports. The pilot needs to clearly see the image on the HUD but also needs to see the real world through the display when it can be seen with the naked eye. In addition, the video display cannot interfere with the display of existing flight information symbology.

“…Methods do include direct and indirect evaluation of the sensor outputs such using terrain database to monitor the integrity of synthetic vision systems [6] and using forward-looking remote sensors to monitor the integrity of stored geo-spatial data [7]. Other methods include the integration of the two information sources in a complementary manner, GNSS and IRS for example, and evaluation via a screening test of the innovations (on a per measurement basis).…”

In order to pursue solutions that simultaneously increase the flight crew's ability to avoid, detect, and recover from unexpected events while also providing countermeasures to pilot error, an onboard Hazard and Integrity Monitor (HIM) function as well as an Integrated Alerting and Notification (IAN) function have previously been proposed to detect and assess hazards, and issue integrated and prioritized alerts and notifications to the flight crew. The objective of these functions is to mitigate hazards introduced by the operators, the application of automation, and the environment. This paper presents a simulation environment developed for verification and validation of the HIM and IAN concepts.This simulation environment models aircraft communication, navigation, surveillance, and health reporting systems and sensors, along with their respective error models. The environment allows for test and evaluation of HIM and IAN concepts under varying sensor and data link configurations and can easily be interface with human-in-the-loop simulators as well. Because of its flexibility of the onboard avionics configurations, this simulation environment can also be used to test other new avionics sensors and algorithms.
