OI 108209: Increase Capacity and Efficiency Using Area Navigation (RNAV)
and Required Navigation Performance (RNP)
Both RNAV and RNP will enable more efficient aircraft trajectories. RNAV and RNP, combined with airspace changes, increase airspace efficiency and capacity.
Task Force: Runway Access
Use Converging Runway Display Aid (CRDA)
This activity is assessing the current use of CRDA functionality and facilitating the development of procedures to extend its use. It also supports the implementation of an arrival/departure window tool at selected sites.
Task Force: Increase Capacity and Throughput for Converging and Intersecting Runways (9)
OI 102140: Wake Turbulence Mitigation for Departures (WTMD): Wind-Based
Wake Procedures
Procedures are developed at applicable locations based on the results of analysis of wake measurements and safety analysis using wake modeling and visualization. During peak- demand periods, these procedures allow airports to maintain airport departure throughput during favorable wind conditions. A staged implementation of changes in procedures and standards, as well as the implementation of new technology, will safely reduce the impact of wake vortices on operations. This reduction applies to specific types of aircraft and is based on wind transporting an aircraft’s wake away from the parallel runway’s operating area.

OI 102141: Improved Parallel Runway Operations
This improvement will explore concepts to recover lost capacity through reduced separation standards, increased applications of dependent and independent operations, enabled operations in lower-visibility conditions and changes in separation responsibility between air traffic control and the flight deck.
Task Force: Runway Access
Additional 7110.308 Airports
This increment provides airports with maximum use of closely spaced parallel runways by authorizing participating aircraft to operate at reduced lateral and longitudinal spacing on dependent, instrument approach procedures to runways with centerline spacing less than 2,500 feet. It will expand the application of FAA Order 7110.308 beyond the locations and the runway ends already approved and implement this capability using available ground and airborne equipment, existing displaced runway thresholds, historical wind data and procedural modifications to instrument approach procedures to maximize the reduced separation benefit.
Task Force: Increase Use of Staggered Approaches (12)
Implement Satellite Navigation (SATNAV) or ILS for Parallel Runway Operations
This increment will enable policy, standards and procedures to allow use of SATNAV or ILS when conducting simultaneous independent and dependent instrument approaches, and implement this new capability at approved locations.
Task Force: Implement CSPO: SATNAV or ILS (37a)
Amend Independent Runway Separation Standards in Order 7110.65 (Including Blunder Model Analysis)
This increment amends runway spacing standards to achieve increased access to parallel runways with centerline spacing less than 4,300 feet and implements this change at approved locations.
Task Force: Revise the Blunder Assumptions (13)
Wake Turbulence Mitigation for Arrivals-Procedures (WTMA-P) for Heavy/757 Aircraft
This increment allows Heavy and Boeing 757 aircraft to lead a dependent, staggered instrument approach procedure to closely spaced parallel runways at spacings less than the single-runway separation used today.
Enable Additional Approach Options for New Independent Runway Separation Standards
This increment will enable use of additional Global Positioning System-based approach options with vertical guidance that may include Lateral Navigation/Vertical Navigation, RNP, and RNP Authorization Required for use in performing simultaneous independent parallel instrument approaches to runways at reduced lateral runway separation, i.e., less than 4,300 feet. Further analysis is required to determine the supported lateral runway spacing. These additional approach options will allow for continued use of higher throughput procedures, for example, if the Instrument Landing System (ILS) is out of service or where no ILS currently exists.
Amend Dependent Runway Separation Standards in Order 7110.65
Based on data collected and analyzed in connection with the amendment of independent runway separation standards in FAA Order 7110.65 (including blunder model analysis), it is likely that a reduced diagonal stagger separation standard can be supported and meet the required level of safety. Work accomplished under this increment will support the safety analysis and additional work required to identify a revised separation standard and revise 7110.65 to permit this operation.
