Initiatives Currently Underway

• Reduced Longitudinal Separation Minimum (RLongSM) – 5-minute longitudinal separation applied between eligible pairs – Gander & Shanwick Control Areas – Eligibility: MNPS Authorization, FANS 1/A CPDLC & ADS-C

connection – Tracks to be loaded using RLongSM at a TBD future date

• Data Link Mandate (DLM) Phase 1 – 2 core OTS tracks (identified in OTS track message), FL 360-390

(inclusive) – Data Link authorization in accordance with State requirements – FANS 1/A (or equivalent) CPDLC & ADS-C operation required

5

RLongSM & DLM Phase 1

-

Initiatives Currently Underway

• 30 NM lateral, 30 NM & 50 NM longitudinal separation – Applied in New York Oceanic between eligible aircraft pairs – 30 NM requirements: RNP 4, CPDLC & ADS-C – 50 NM longitudinal requirements: RNP 10, CPDLC & ADS-C

• 50 NM lateral separation in Santa Maria Oceanic – Starting 6 March 2014, 50 NM lateral separation applied to aircraft

authorized RNP 10 (minimum) or RNP 4 – MNPS authorization required – Aircraft not authorized RNP 10 or RNP 4 will be accommodated

using 60 NM lateral separation

Initiatives Currently Underway (cont.)

• Used currently in Canadian coastal regions and southern Greenland primarily to aid in enabling climb and descent

• Iceland and Portugal scheduled to implement ADS-B services in 2014

• Compliance required with EASA AMC 20-24 or equivalent • Avionics functionality compliant with DO 260, Do 260A or

DO 260B • NavCanada AIC 31/11 addresses operator requirements for

Operational Specifications or completion of an equipment survey • NavCanada AIC 29/13 supplements AIC 31/11 with Flight Crew

& ATC procedures

ADS-B Out (5-10 NM separation)

.

FANS 1/A (or equivalent) Data Link Mandate

• Equipage with and use of CPDLC and ADS-C required in DLM airspace with limited exceptions (e.g., State, Humanitarian)

• Objective: enhance comm, surveillance and ATC intervention capabilities to reduce collision risk

• Plan announced in ANSP AICs and FAA Notice in 4/Q 2013 • Non-DLM airspace: DLM not to be applied in NAT ATS

Surveillance Airspace, north of 80 north or, until regulatory action completed, in New York Oceanic

• NAT ATS Surveillance Airspace: surveillance provided by radar or ADS-B to suitably equipped aircraft (transponder/ADS-B Extended Squitter transmitter)

NAT DLM Plan Overview

-

NAT Data Link Mandate

• DLM Phase 2A: 5 Feb 2015 target date – DLM to be implemented on all NAT OTS tracks between FL 350-390

(inclusive). Operation in non-DLM airspace remains an option • NAT DLM Phase 2B: 7 Dec 2017 target date

– DLM to be applied in all NAT Region airspace between FL 350-390 (inclusive)…except specified non-DLM airspace

• NAT DLM Phase 2C: 30 Jan 2020 target date – To be applied in all NAT Region airspace at FL 290 and

above…except specified non-DLM airspace • See previous slide for non-DLM airspace

Preliminary Depiction to be updated in 2014

.

Reduced Lateral Separation Minimum

• 25 NM lateral separation and ½ degree track spacing to be applied on designated tracks

• ½ degree waypoints to be used to define RLatSM tracks (e.g., 54 degrees-30 minutes North, 30 degrees West)

• Only RLatSM eligible aircraft will operate on RLatSM tracks and adjacent tracks

• Operators need to determine if their aircraft nav databases will need update with NAT ½ degree waypoints (NavCanada leading effort to make ½ degree waypoint data package available in November/December timeframe)

• Strategic Lateral Offsets (SLOP) will continue to be used

11

RLatSM trial provisions

.

RLatSM Trials

• ADS-C functionality includes: – Conformance monitoring alerts controller when reports do not match current flight

plan (monitors NEXT waypoint and NEXT PLUS 1) – ADS periodic contracts at specified intervals – ADS event contracts include the following:

• lateral deviation event (LDE) of 5 NM or less; • level range deviation event (LRDE) 300 ft. or less; and • waypoint change event (WCE) at compulsory reporting points.

• CPDLC provides enhanced ATC intervention capabilities

• Operator/Aircraft Requirements – MNPS authorization – RNP 4 authorization – CPDLC and ADS-C equipage and operation – All RLatSM CNS systems required to be operational

12

Enabling technology

.

RLatSM Trials

• RLatSM Phase 1 trial planned start date: 5 Feb 2015 – 25 NM lateral separation to be applied on three core OTS tracks

between FL 350-390 (inclusive) – RLatSM tracks to be identified in OTS track message

• RLatSM Trial Phase 2: target date 1/Q 2016 – RLatSM planned to be applied on all OTS tracks between

FL 350-390 (inclusive) • RLatSM Phase 3: target date is TBD

– RlatSM planned to be applied between eligible aircraft in the NAT Region between TBD FLs

13

(Trial Phases)

-

RLatSM Trials

• Pilots must understand ½ degree waypoint display on aircraft maps and FMCs

• Pilots must be disciplined in executing waypoint insertion procedures to avoid navigation errors – Will need to independently confirm correct insertion of degrees and

minutes of latitude and longitude for each waypoint – Will need to independently perform checks to compare Computer

Flight Plan to FMC track and distance • Pilots must be prepared to execute ICAO Doc 4444 contingency

procedures for turn-backs, diversions and for weather deviations to avoid conflict with other aircraft

14

Operator responsibilities

.

RLatSM Trials

• Pilots should maximize use of TCAS II (ACAS II) for situational awareness and collision avoidance – Provisions for operational TCAS II (ACAS II) under discussion

• Operator guidance and direction on RLatSM operations being developed in NAT SPG working groups

15

Operator Responsibilities (cont.)

.

MNPS to PBN Transition Plan

• 2013 – Use of RNP 10 as Navigation Specification (NavSpec) to qualify for

MNPS authorization endorsed in NAT Regional SUPPS – Use of MNPS NavSpec remains valid

• 2015 – Proposed for 1 Jan 2015: RNP 10 (minimum) and RNP 4 to replace

MNPS as NavSpec for NEW MNPS authorizations – Existing MNPS authorizations not affected – Date TBD: MNPS designation for NAT airspace will be replaced

with designation oriented to “Performance Based Operations” – Current proposal is: “NAT High Level Airspace”

16

Performance-based Navigation (PBN) transition

-

MNPS to PBN Transition Plan

• 2020 – All aircraft operating in NAT “PBO” airspace will be authorized

RNP 10 (minimum) or RNP 4 – MNPS NavSpec no longer valid

• State (country) authorization processes – Individual State authorization processes and documents will need to

be updated to reflect MNPS transition provisions – Operators will need to coordinate with their State authorities to

determine State requirements as transition progresses

17

Continued

.

Performance Based Comm & Surveillance

• Required Communication Performance (RCP) Type: a label (e.g., RCP 240) that represents values for communication transaction time, continuity, availability and integrity parameters

• Required Surveillance Performance (RSP) Specification: a set of ATS provisions, including communication services, aircraft and operator requirements (e.g. RSP 180) needed for surveillance performance within a defined airspace.

• NAT PBCS Implementation Plan being progressed by NAT SPG working groups. NAT CNS Group is the lead.

18

PBCS Implementation Plan

.

NAT PBCS Implementation

• RCP 240 and RSP 180 being used to assess CPDLC and ADS-C performance in NAT operations

• Provisions to incorporate RCP and RSP into operator data link programs and, where applicable, operator data link authorizations are being progressed in ICAO Panels and NAT SPG groups

• Suggest that operator groups remain informed on development of PBCS implementation plans

19

Status

.

Conclusion

• Operators need to remain informed on status of NAT projects

• ICAO EUR/NAT Office Website and FAA NAT Resource Guide For US Operators serve as sources for operator information

• NAT Doc 009 (NAT Service Development Roadmap (SDR)) posted on ICAO Paris EUR/NAT Office Website under NAT Documents

• SDR provides a listing of NAT initiatives along with schedules for their progression
