OI 108209: Increase Capacity and Efficiency Using Area Navigation (RNAV)
and Required Navigation (RNP)
RNAV and RNP can enable more efficient aircraft trajectories. Combined with airspace changes, RNAV and RNP increase airspace efficiency and capacity.
Task Force: Metroplex, Cruise and Overarching
Integrated Airspace and Procedures
Large-Scale Redesign of Airspace Leveraging Performance Based Navigation (PBN)
Airspace and procedures solutions that do not fit within the environmental and criteria boundaries of an Optimization of Airspace and Procedures in the Metroplex (OAPM) project become candidates for other integrated airspace and procedures efforts. Included in this increment are the legacy airspace management program projects. Although these are considered legacy projects, many of the efficiencies and benefit gains will come from optimized PBN procedures.
Task Force: Integrate Procedure Design to Deconflict Airport, Implement RNP with RF Capability, and Expand Use of Terminal Separation Rules (4, 21a and 32b), Increase Capacity and Throughput for Converging and Intersecting Runways (9)
Transition to PBN Routing for Cruise Operations
This approach augments the conventional navigational aid (NAVAID)-based Jet and Victor airways with RNAV routes, including Q- and T-routes. RNAV routes offer an efficient way to navigate the airspace instead of NAVAID-to-NAVAID routing.
Task Force: Develop RNAV-Based En Route System (30)
OAPM
OAPM is a systematic and expedited approach to implementing PBN procedures and associated airspace changes in major metropolitan areas. Expected improvements from OAPM include efficient descents, diverging departure paths and decoupling of operations among airports within the metroplex airspace.
Task Force: Optimize and Increase RNAV Procedures (32a and 29)
Navigation System Infrastructure
NextGen En Route Distance Measuring Equipment (DME) Infrastructure
Additional DME coverage over the continental United States is needed to optimize and expand RNAV routes by closing coverage gaps at and above Flight Level 240.
Air Traffic Tools/Automation PBN Route Eligibility Check
En route air traffic control automation systems will check the eligibility of aircraft to operate on performance-restricted routes.
Relative Position Indicator (RPI)
RPI is a tool that can assist both air traffic controllers and traffic managers in managing the flow of traffic through a terminal area merge point.
Flight Management Computer (FMC) Route Offset
Automation provides controllers with support to amend an aircraft’s flight plan to indicate that it has been placed on, or has been taken off, an FMC lateral offset.
OI 107103: RNAV Standard Instrument Departures (SID), Standard Terminal
Arrival Routes (STAR) and Approaches
RNAV is available throughout the National Airspace System (NAS) using satellite-based avionics equipment and systems.
Task Force: NAS Access
RNP and RNP Authorization Required (AR) Approaches
RNP and RNP AR approaches are PBN operations that are implemented to meet the needs of the airspace users and airports in terms of efficiency, safety and access. A key feature of RNP and RNP AR approaches is the ability to use curved, guided path segments known as radius-to-fix (RF).
RNAV SIDs and STARs at Single Sites
These RNAV procedures address location-specific requirements and seek to add efficiency and optimize existing initial capability PBN procedures.
