PMA209 2012 Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2012 Appendix A-5Mandates and Milestones:DoD Encryption of Data at Rest Policy Memorandum. (Jul 2007) Establishes policyfor protection of sensitive unclassified information on mobile computing devices andremovable storage media. All unclassified data stored on removable storage devicesmust be treated as sensitive and be encrypted per standards set by the NationalInstitute of Standards and Technology (NIST) Federal Information Processing Standard140-2 (FIPS 140-2). This standard affects data storage devices as well as missionplanning and mission recording information handling. This policy is an extension ofguidance provided in DoDI 8500.2, Information Assurance (IA) Implementation.OPNAVINST 13210.1A Naval Aviation Policy for Aircraft Safety Systems Avionics.(03 Sep 2009) Directs incorporation of specified flight safety capabilities: Controlled Flight Into Terrain (CFIT) avoidance. Crash survivable aircraft parameter, flight information and audio recording. Airborne collision avoidance protection. Military Flight Operations Quality Assurance (MFOQA).Required system performance parameters are delineated for each of the capabilities. Itcalls for compliance reviews to be conducted at each program milestone, andencourages pursuit of common system solutions. Waiver requests are to be submittedto OPNAV (N98) and must include type/model/series, which safety element is beingrequested for waiver, justification for the waiver, assessment of risk, actions takentoward compliance and plan ahead to achieve compliance.Automatic Dependent Surveillance – Broadcast Out (ADS-B Out) in NationalAirspace. (2020) FAA established the requirement for aircraft operating in high densitytraffic airspaces within the National Airspace (NAS) to be equipped with ADS-B “Out”functionality by 2020. Non-compliance may result in airspace exclusion.Capability Element Evolution:A. Terrain and Obstacle Avoidance. This capability element addresses thecapability to provide awareness to the pilot of potential ground and/or man madeobstacle impact to prevent CFIT mishaps.1. Current capabilities. Predictive terrain awareness warning.There are two primary CFIT avoidance solutions integrated into several platforms.Ground Proximity Warning System (GPWS) software is an embedded implementation ofan algorithm that uses aircraft dynamics and sensor data to determine whether there isa high risk of CFIT. If such a risk is found to be present, the pilot is provided a directivecue (i.e., the pilot is told what maneuver to execute in order to initiate safe recovery ofthe aircraft from the CFIT condition). Terrain Awareness Warning System (TAWS) usespredictive software algorithms improve CFIT warning capability by comparing aircraftaltitude, attitude, and airspeed developed from GPS and/or Inertial Navigation System(INS) against on-board Digital Terrain Elevation Data (DTED) database information.This capability is only available to those platforms that can host the database and havesufficient processing power to drive the TAWS algorithm. TAWS provides improveddynamic flight profile protection over GPWS as well as aural or visual cues that havebeen credited for saving aircraft. Since incorporating TAWS, there has not been oneF/A-18E/F CFIT mishap.A-5 Flight Safety 3
