Core Avionics Master Plan 2011 Appendix A-52. Advanced Research and Technology Development.DVE Situational Awareness (SA) Enhancement. (2010-2012) There are severaladvance research activities underway to explore technologies that could supportimproved SA in DVE scenarios. PMA261 (H-53 variants) is currently managing industrydemonstrations and reviews of prototype systems, analyzing them for weight, size,power requirements, versatility, effectiveness and cost. PMA209 is tracking two SmallBusiness Innovative Research (SBIR) initiatives that are testing the use of FlashLADAR to enable aircrew to see through airborne particulates or to “see and remember”an environment so that a virtual representation can then be created for safemaneuvering. The Office of Naval Research (ONR) is managing the Helicopter ProductII effort in support of associated Future Naval Capabilities (FNCs) which is exploringboth LADAR and Passive Milli-Meter Wave (PMMW) technologies for similar objectives.These pursuits can also serve to achieve improvements in obstacle avoidance.3. Funded Enhancements and Potential Pursuits.Improved CFIT Warning (DTED Level II). (2013) Higher fidelity DTED informationis required to adequately protect platforms when they operate closer to the ground.DTED Level I is the basic medium resolution elevation data source for all militaryactivities and systems that require landform, slope, elevation, and/or gross terrainroughness in a digital format. The information content is approximately equivalent to thecontour information represented on a 1:250,000 scale map (100 m post spacing). DTEDLevel II (DTED2) is a higher resolution elevation data source that is equivalent to thecontour information represented on a 1: 50,000 scale map (30 m post spacing).Improved Degraded Visual Environment (DVE) Situational Awareness. (2016)Naval Aviation Center for Rotorcraft Advancement (NACRA) has adopted the DVEissue as a primary objective for a streamlined solution. Several technologies andoptions are being reviewed for affordability, degree of capability provided and potentialfor near term implementation. Potential solutions include improved aircraft attitude, driftand hover cues, automated hover controls, sensors that could either enable the crew tosee through the degraded environment or sensors that detect the ground and obstaclesand then present a clear virtual visual presentation.Obstacle Avoidance (TAWS2). (2016) TAWS managers are integrating obstacledatabase information into DTED2 database information (TAWS2) and designingalgorithms to provide warning and maneuver guidance for avoiding collisions with fixedobstacles such as towers. DTED Level I is the basic medium resolution elevation datasource for all military activities and systems that require landform, slope, elevation,and/or gross terrain roughness in a digital format. DTED1 is a uniform matrix of terrainelevation values with post spacing every 3 arc seconds (approximately 100 meters).The information content is approximately equivalent to the contour informationrepresented on a 1:250,000 scale map. DTED 2 is a uniform gridded matrix of terrainelevation values with post spacing of approximately 30 meters. The information contentis equivalent to the contour information represented on a 1:50,000 scale map. Modernsystems are hosting the significant increases in memory and processing power requiredto enable TAWS2. The increased database fidelity is required for low level operationsand improved obstacle avoidance.A-5 Flight Safety 4
