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
7
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)
8
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 NEW target date: 12 Nov 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 Phase 2 trial target date: approx. one year after
Phase 1 start date
– 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

.
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
