220225 ILSGLSLPV Hot Temp Intermediate Segment
220225 Parc Steering Group Recommendations 03 Nav Incoming Letter
|
The Performance-based Operations Aviation Rulemaking Committee (PARC) Navigation Working Group recommends the FAA update the Appendix C. “PBN Transition to ILS/GLS/LPV Final” language in FAA Order 8260.58 to better protect pilots coming from downwind to a short Final Approach Segment (FAS), ensuring that aircraft “capture” the geometric glideslope or glidepath from below, without the need to update the procedures with lower altitudes that adversely affect the communities at the airports these approaches serve. | Open | |

220309 EOR Criteria Phraseology Harmonization
220309 Recs EOR Criteria Phraseology Harmonization
|
The Performance-based Operations Aviation Rulemaking Committee (PARC) Navigation Work Group (NAV WG) recommended the FAA amend the criteria for EoR to remove the requirement to have a unique path for at least 50 seconds prior to crossing the first Final Approach Course (FAC). The PARC Pilot-Controller Procedures and Systems Integration Work Group (PCPSI WG) provided the FAA with the report of the PCPSI Phraseology subgroup recommendations on how the U.S. might better align with International Civil Aviation Organization (ICAO) phraseology used for “Climb Via” and “Descend Via” |
Open | |
|
RECOMMENDATION 1: The FAA should standardize the survey requirements for the height and location of aeronautical obstacles across all lines of business.
RECOMMENDATION 2.: After standardizing the aeronautical survey standards and requirements, the FAA should standardize the procedure design criteria application of identified obstacles across all different types of procedures. |

20221013 PARC RF Construction on RNP APCH with Extended Visual Segment Recommendation
|
Combining the RNP APCH operations that include an Extended Visual Segment with the RF/TF concurrent operations would allow for maximum participation with the TF version but also allow the increased safety afforded by those that invested in RF capability. | Open |

210203 Standards for Implementation of RNP APCH procedures with Extended Visual Segment (PDF) PARC RNP APCH Recs Action Plan DS-Response |
The PARC Navigation Work Group (NAV WG) recommended criteria changes to normalize the construction and use of RNP Approaches (RNP APCH) with extended visual segments. The RNAV (GPS) Z RWY 13L procedure at JFK International airport is this type of approach and was an excellent benchmark to conduct an analysis and develop standards for these procedure designs which will enhance efficiencies and safety by providing continued lateral and vertical guidance in the visual segment of the RNP APCH procedure. | Open | |
| 210203 Use of DME Fixes in current or future RNAV procedures (PDF) | The PARC Navigation Work Group (NAV WG) recently completed a review and analysis of issues that have arisen when a VORTAC and VOR/DME is decommissioned, and a stand-alone DME facility remains at the same geographic location. Some inconsistencies in the process have led to confusion for flight crews and in some instances extends to communication confusion between flight crews and ATC. | Open | |
|
|
The Performance-based Operations Aviation Rulemaking Committee (PARC) Navigation Work Group (NAV WG) recommends the Steering Group (SG) adopt the criteria and forward the recommendations to the Federal Aviation Administration (FAA) for consideration and implementation. Adopting the criteria will standardize implementation of future RNP APCH operations requiring application of an extended visual segment. |

| RF/TF concurrent Ops Methodology Validation Report (PDF) | The PARC Navigation Work Group (NAV WG) recently completed an analysis for conducting instrument approach procedures (IAPs) using two separate RNAV procedures that are constructed using radius-to-fix (RF) legs or track-to-fix (TF) legs respectively, and flying those procedures to the same runway end concurrently.

| Removal of 2 NM FROP to FAF Requirements (PDF) | The PARC Navigation Work Group (NAV WG) recently completed an analysis of design criteria for RNAV approaches that use an RF leg to join the final course. Currently the criteria requires a 2NM straight segment prior to the PFAF. These criteria should be aligned with the existing criteria for RNAV to xLS in FAA Order 8260.58A Appendix C. | Revise Order 8260.58 policy for RF legs that join final segment by eliminating requirement from 2NM straight segment prior to the PFAF. Coordinate with Instrument Flight Procedure (IFP) Service providers to integrate change into IFP design software. Directive change targeted for coordinated software release/FAA implementation date. | Open |
| Recommendation for STAR speeds change (PDF) | Current procedure design criteria sets the minimum speed for design at 250 KT above 10,000 MSL for Category C and D aircraft on a STAR. This limits design options especially at high altitude airports like KDEN. The recommendation changes that to match holding airspeeds between 6000 and 14000 MSL fixing the minimum at 210 KTs. This will avoid many waivers that are routinely granted for STARs at higher elevation airports. |
