Joint Precision Approach and Landing System
Abstract
JPALS is an Acquisition Category ID program with joint partners for requirements and acquisition including the USAF, USN/USMC, USA, and the Federal Aviation Administration (under the Next Generation (NextGen) Air Transportation System Program). JPALS is being developed using an incremental approach employing a family of systems (FOS) to ensure joint, allied, coalition and Federal Aviation Administration/International Civil Aviation Organization interoperability. On 16 March 2007, the Joint Requirements Oversight Council (JROC) approved the Capability Development Document (CDD) for the JPALS Family of Systems (FoS) and Increment 1 for the Sea-Based System and designated the Navy as the JPALS lead Department of Defense (DoD) Component. On 19 January 2010, the JROC approved Increment 2 for the Land-Based System and designated the Air Force as the lead component for the Land-Based System. JPALS is the next generation global positioning system (GPS)-based precision approach and landing system for the DoD. It will replace several aging and obsolete aircraft landing systems with a FoS that will function in more operational environments and in a wide range of meteorological conditions. Because a cornerstone of the JPALS implementation strategy is worldwide and civil interoperability, JPALS must harmonize with US and International Civil Global Navigation Satellite Systems. This is being accomplished through participation in the development testing, and implementation of international standards through the North American Treaty Organization (NATO) the International Civil Aviation Organization (ICAO). Interoperability of the JPALS ground systems with all military and civil aircraft is a key aspect of the planned system. Military aircraft must have worldwide access to civil and military airfields/air stations/operating locations in benign and hostile (jamming) environments. The JPALS Land-based Increment 2 system will provide a civil interoperable capability and also a military interoperable encrypted, jam-resistant capability. FY12 efforts continue risk reduction activities related to incorporating JPALS capability in existing avionics and evolution of the acquisition strategy in preparation for Milestone B. This includes completion of the technology readiness assessment with the Office of the Secretary of Defense participation and a greater emphasis on aircraft integration activities. Test planning activity will ramp-up in advance of the Engineering, Manufacturing and Development (EMD) contract award in FY12. JPALS will close capability gaps identified in the Precision Approach and Landing Capability Initial Capabilities Document. These gaps include: interoperability for naval aircraft landing at shore-based airfields operated by other services, interoperability for Navy/Marine Corps and Army aircraft landing at civil airports, and for the Civil Reserve Air Fleet landing at DoD airfields. This program is in budget activity 4, Advanced Component Development and Prototypes (ACD&P), because efforts are necessary to evaluate integrated technologies, representative modes or prototype systems in a high fidelity and realistic operating environment.

- Change Summary Explanation
- The funding increase starting in FY12 reflects decision to move the JPALS Land-Based Increment 2 initial operational capability from FY19 to FY17 and Milestone B from FY15 to FY13. This change aligns the Land-Based Increment 2 with the Sea-Based Increment 1 initial operational capability timelines.
