COVID Impacts to Terminal Flight Data Manager

• All TFDM-related travel, since March 20th, has been restricted only to

activities related to sustainment of critical NAS systems.

• Limited access to the FAA Atlantic City tech center for testing

‒ Currently, no access to training academy (for training technicians)

• No access to air traffic facilities (to conduct installation, testing, training)

• NAC Milestones on “TBD” status until there is better fidelity of information

regarding re-planning efforts and COVID-related constraints.

‒ TFDM B1 IOC in PHX will postponed till 2021

• While TFDM deployment activities are restricted, FAA continues to make

progress:

‒ TFDM software development and adaptation continues

‒ TFDM software “remote testing” initiated

TFDM Testbed

• Flight Operators connect to a Simulated NEMS node and SWIM cloud

to connect to TFDM’s TTP and TFCS services

• Allows flight operators to understand new TFDM data and how that

data is interfaced to flight operator systems

• To help flight operators prepare for TFDM and new data flows, TFDM

program will offer a testbed to connect with

• Testbed will start in Fall 2020

17

SWIM Industry FAA Team (SWIFT)

• SWIFT addresses our industry’s evolution toward actionable data and insight

• Collaborative Decision Making (CDM), admittedly the gold standard in traffic flow

management, began with a simple premise on exchanging data to better manage

the NAS.

• Designed to address a NAC request to provide operational context to the IT-centric

documentation for information available on SWIM, SWIFT has grown to improve

communications across a broader set of NAS stakeholders needs with NAS SWIM

producer systems

• As the aviation community becomes more data-centric, operationally and analytically,

the SWIFT forum is evolving to capture the myriad needs of industry and FAA alike as

a clearinghouse for collaborative engagement around NAS information and data

sharing and producer system data requirements

• SWIFT supports digital collaboration across the traditional aviation community as

well as new NAS entrants, enabling iTBO/TBO and Future Flow Management

• SWIFT Meetings are held quarterly and are included in the industry NJIP

46

Northeast Corridor - Key Issues and Status

• 2020/2021 Commitments

‒ Due to COVID-19, facility access limitations, travel restrictions and fiscal

austerity will delay completion of several commitments (e.g. ACR and GBAS)

‒ Virtual meetings allow continuation of coordination and planning (e.g.

Industry TOS discussions)

• Advancing pre-implementation milestones

‒ LGA Runway 31 RNAV GPS collaborative meetings are continuing

‒ High-performance escape routes for TEB/HPN

• Looking ahead – meetings planned thru Nov NAC

‒ Additional discussion on pre-implementation milestones

‒ Support to Ad Hoc Teams and other NIWGs

‒ Focus on priorities that support agile recovery, specifically within the NEC

Task 18-4: Northeast Corridor: Implementation Risks and Mitigations of the NextGen Priorities Joint Implementation Plan

“The FAA requests that the NAC identify Northeast Corridor risks and

mitigations to the successful operational implementation of industry

commitments with respect to the NextGen Priorities Joint Implementation

Plan through calendar year 2021. This should also include any needed

industry mitigations to support successful operational integration of the

joint commitments.”

‒ Operational facilities are most impacted

‒ Simulators and laboratories also impacted

• FAA and Industry training impacted

‒ Access to training labs and availability of personnel

• Travel has been suspended for FAA and Industry

• Fiscal austerity impacting investment

• Dramatic reduction in traffic levels across US but very pronounced in

the Northeast

54

COVID Impact on Initiatives Highlighted at December 2019 NAC

Atlantic Coast Routes (original Nov 2020, now late 2021):

• Meetings with flight planners can continue virtually

(e.g. briefing to JetBlue in March 2020)

• Controller training and facility access are challenges

• Aligning with other project waterfalls

Philadelphia Metering Initiatives

(still late 2021):

• SW development can continue

• Controller training and facility

access are challenges

Washington Center Redesign

(original Oct 2020, now late 2021):

• Controller training and facility access

are challenges

55

Impact on Remaining 2019-2021 NJIP Commitments

• Five remaining NEC implementation commitments

‒ Four in CY2020: Delays expected for all remaining CY2020

commitments

o Improved departure management for flights destined to LGA

o DSP enhancements

o Eastern seaboard high-altitude routes (Atlantic Coast Routes)

o PDRR/ABRR

‒ One in CY2021: No delay reported yet

o Arrival time-based metering (TBFM) for PHL

56

Impact on Remaining 2019-2021 NJIP Commitments

• Eleven remaining NEC Industry commitments

‒ Seven in CY2020:

o PHL airport infrastructure assessments completed early

o Delays expected for four CY2020 commitments

GBAS implementation at LGA

GBAS evaluation at BOS

DCA north end hold pad evaluation

Industry support to ACR implementation (tied to FAA delay)

‒ Four in CY2021:

o Delays expected for one commitments

GBAS implementation at JFK

57

Unique Circumstances Leading to Unique Opportunities in NEC

• Lower traffic levels may provide opportunities to introduce concepts and revisit completed post-implementation milestones

• Returning fleet may have different characteristics

• Focus on operational priorities that support agile recovery

NEC Inputs to “Opportunities” Discussion

LGA RNAV GPS approach to Rwy31: public instrument approach procedure that can

provide a stable and guided path to the threshold of RWY31, enhancing the safety

• LGA GLDMN and JFK 31L SKORR departures: use altitude separation to allow

simultaneous departures; dispersal headings from LGA 13 provide departure

efficiency; also improves efficiency by providing JFK with opportunities to utilize 31L

for departures

• EWR 22L/29 operation: address the loss of a second landing runway at EWR during

southwest to west winds, enabling a significant reduction in minutes of arrival delay

• LGA ILS 13 approach deconflicting TEB/EWR/LGA: deconflicts the three airports, to

improve overall airspace operations and reduce the number of configuration

changes

TEB/HPN escape route: provides for an alternate route out of the airspace for

capable business aviation aircraft

FAA has agreed to pursue

NAC Task 19-1: Minimum Capabilities List (MCL)

Ron Renk, United Airlines

Greg Young, Delta Air Lines

How We Got Here...

• NextGen Integration Working Groups (NIWGs):

‒ Northeast Corridor (NEC)

‒ Performance Based Navigation (PBN)

‒ Data Comm

‒ Surface

‒ Multiple Runway Operations (MRO)

• Many had a common thread in their reports:

*MIXED EQUIPAGE impedes NextGen*

61

Refresher – What is MCL?

The Minimum Capabilities List is a forward-fit list of equipage

that was created by a large segment of the aviation industry to

avoid mixed-equipage issues when implementing NextGen in

the National Airspace System.

Sub-Task 3: Adoption and Commitment

• Scope – To whom does the MCL apply? (DONE)

• Retrofit – “If I took delivery of airplanes just last year, what items would I

need to buy so as not to become an impediment to NextGen?” (DONE)

• Cost/Benefit – “What will this cost me and what will I get in return?”

(INCOMPLETE)

67

Conclusion

• 2 year effort: Level of interest and collaboration was robust

• The Baseline and Supplemental matrices are complete

• No doubt a “WIN” for all stakeholders

‒ Path forward to use technology to improve NAS operations

• In order to assure MCL success, it needs:

‒ High level of participation/adoption from Industry, and

‒ Corresponding FAA investment response

68

Conclusion

• Best outcome – Airlines and General Aviation Operators, that are within

scope, elect to use the MCL to establish aircraft equipage specifications

for OEMs (MCL Baseline becomes standard equipment).

• Though NAC tasking, in spirit, is “complete;” completion of the final

three issues are critical to its success. Due to COVID issues we request

one additional meeting cycle to finalize the effort and provide the NAC

a more detailed conclusion.

Q1 2019

71

Background

• JAT Tasking:

‒ Evaluate expanded consistent usage of defined and existing capping and

tunneling (escape routes) for departures/arrivals to/from the NEC through

required advisories

• What is an escape route?

‒ Escape routes offer a means to increase departure capacity during

significant Severe Weather Avoidance Plan (SWAP) events and during

special events or holiday traffic volume situations

72

Escape Routes - Summary Findings

• Escape route usage increased 92% from 2016/2017 baseline to 2019

• Additional average flight time of ~11 minutes for each escape route

flight

• System delay savings estimated at 10 times the average additional flight

time for escape route usage. Additionally, estimated a savings of one

cancellation for every four escape routes used

• Conservative estimate of achieved benefits delivers increase from

baseline

‒ Baseline: 2016/2017 is $15.5M

‒ 2018 resulted in $8.7M additional savings over Baseline

‒ 2019 resulted in $14.6M additional savings over Baseline

73

Escape Route Usage

74

JAT Goal and Approach

• Evaluate the savings from delay and cancellations enabled by ESCAPE

routes compared to the additional flight time and fuel cost

• Agree on methodology to both determine escape routes flown and

model the expected delay if they were not able to be used

‒ Perform sensitivity analysis to account for uncertainty with weather

events

‒ Calculate change in escape routes flown from 2016/2017 baseline to

2018/2019

‒ Apply standard FAA/JAT valuation for delay and fuel by phase of flight,

and cancellations

• Present final findings to NEC and NAC SC

FAA SMEs: Clark Desing, Wendy O’Connor, & Aaron Wilkins

78

Task 19-4: Performance Based Navigation (PBN) Clarification

The NAC is asked to provide aviation community consensus advice by:

• Developing consensus agreement on a PBN baseline

‒ FAA Procedures

‒ Industry Equipage;

• Developing consensus agreement on a joint definition of a PBN NAS; and

• Developing consensus agreement based on gaps in baseline analysis at Core 30 airports (minus HNL, plus TEB), on a list of specific desired outcomes.

‒ MITRE

81

PBN Baseline for Procedures

• Existing procedures in the NAS

RNAV SIDs and STARs

RNAV GPS Approaches

RNP AR Approaches

RNP to xLS (ILS/GLS)`

Advanced RNP (A-RNP) (SIDs, STARs, Approaches)

Ground Based Augmentation System Landing System (GLS)

Approaches

RNAV Visual Flight Procedures (RVFP)

• A-RNP exists in the NAS but is in various stages of development and

maturity

• All but RNAV Visuals are part of the NAS NAV Strategy

82

PBN Baseline Equipage

• NAC Minimum Capabilities List (MCL) was used to identify the PBN

capabilities for Approach and Terminal phases

• Information from Table 1 from Operations Specifications (Ops Specs)

C052, C063 and C384 were used along with the total fleet size to calculate

equipage percentages

• Updated in June 2020, but subject to change

83

Consensus Agreement on a PBN NAS

• The Ad Hoc Team endorses the 2016 NAS NAV Strategy as the

definition of a PBN NAS

‒ Including the “Key Principles” and “Navigation Strategy

Overview”

• The introductory remarks of then-FAA Administrator Michael P.

Huerta are still relevant and are an accurate reflection of the

definition of a PBN NAS:

“A truly PBN-centric NAS, that is, a NAS where PBN is used as the basis for daily operations. It charts a course that will allow the public and private sectors to advance the NAS collaboratively and constructively for the benefit of all aviation stakeholders, including aircraft operators, the traveling public, as well as new entrants such as unmanned aircraft systems and commercial space vehicles.”

84

Consensus Agreement On Specific Desired Outcomes

• Identify gaps in baseline analysis at Core 30 airports (minus HNL, plus

TEB)

• Post tasking airport considerations

‒ Cargo Carrier airports and other vital airports outside of the Core 30

‒ DEN, LAS and Florida Metroplex excluded

• Airports were individually prioritized by the operators

‒ Desired PBN outcomes proposed for each airport

• Ranking the procedures was based on Readiness and Return scoring

metrics

85

Summary of Aviation Community Readiness and Return

NOTE: This is the list the FAA will work from to

determine what procedures are within scope and

can feasibly be developed

86

FAA Procedures Analysis and Final Outcome

• The Aviation Community has submitted 48 proposals as “Desired Outcomes” from the modified Core 30 airports and some airports not included in the tasking letter

• The FAA SMEs have conducted an initial internal analysis to determine the status of some recommendations. Further FAA analysis needs to be conducted regarding scope, feasibility, environmental considerations, and available resources to provide a final list of procedures consistent with FAA planning.

• The PBN Clarification Ad Hoc Report contains the list of recommendations to move PBN development forward in the near term
