NAT Circle of Change 2018

For the latest changes and updates on the North Atlantic, including our most recent Guides and Charts, use our NAT reference page at flightservicebureau.org/NAT.

Update Feb 7, 2018: We screwed up the circle. NAT Tracks don’t all need CPDLC and ADS-C, just the ones from FL350-390. Circle admonished and corrected.

Confused and overwhelmed with the changes on the North Atlantic of late? Especially with PBCS, RCP240, RSP180, RLAT, RLong, and all that? Yep, us too.

So, we drew a circle. Tell us if this helps. Click on the circle to download the more detailed PDF.

2018
 is off to a flying start again with NAT changes – these are the latest important changes. These are also published in the latest edition of NAT Doc 007, January 2018.

  • PBCS From March 29th 2018, PBCS is a requirement for the NAT Tracks between FL350-390 – RCP240 and RSP180. Read more about PBCS in our article.
  • RLAT  From January 4th 2018, Shanwick and Gander increase the number of RLAT tracks – most tracks between FL350-390 will now be RLAT – 25nm separation between them.

And there will be more! Keep an eye on the FSB NAT Changes page, we’ll keep it updated.

 


Feb 2nd, 2018: FSB updated the full NAT Crossing Guide “My first North Atlantic Flight is tomorrow“.

– What’s different about the NAT, changes in 2018, 2017, 2016, 2015, NAT Quick Map
– Routine Flight Example #1 – Brussels to JFK (up at 5.45am)
– Non Routine-Flights: No RVSM, No RNP4, No HF, 1 LRNS, No HLA, No ETOPS, No TCAS, No Datalink – what you can do and where you can go
Take a look.


PBCS: New rule on the NAT from March 29, 2018 – RCP240 and RSP180

Update March 16th, 2018: PBCS is turning into a PITA. After OPSGROUP input, we have an update on the latest status including rumours of delays, A056 LOA’s, and Aircraft that have failed to comply with PBCS.

For the latest changes and updates on the North Atlantic, including our most recent Guides and Charts, use our NAT reference page at flightservicebureau.org/NAT.

ICAO is introducing another acronym in the North Atlantic Region. This time, it’s PBCS (Performance Based Communication and Surveillance), and from March 29th 2018 you will need to be compliant if you want to fly on the half-tracks between FL350-390.

Initially, there will only be a maximum of three daily tracks where you will need to be PBCS-compliant between FL350-390. These will likely be the same tracks as we currently see being assigned as ‘half-tracks’ each day.

This requirement will eventually be extended to all the NAT tracks between FL350-390, but we understand that will only happen when the filing of PBCS designators on flight plans reaches the 90% mark, or 28th March 2019 – whichever comes first. Either way, the ‘transition period’ for this PBCS implementation is set to last six months, so the roll-out of the requirement to all the tracks won’t happen until Oct 2018 at the earliest!

But from March 29th 2018, Shanwick and Gander will basically just continue the concept used in the RLatSM trial – whereby daily tracks spaced at less than 60nm from an adjacent track will be specified as a ‘PBCS Track’ and will be notified in the Track Message Remark-3.

So what is PBCS?

PBCS is the thing that will replace two trials in the NAT which are both coming to an end on March 29th:

  • RLATReduced Lateral Separation Minimum: where a reduced lateral separation of 25 nm has been implemented on the tracks between FL350-390 (so now there are extra “half tracks” each day, spaced by one-half degree of latitude)
  • RLong – Reduced Longitudinal Separation Minimum: in the Shanwick Oceanic Control Area (OCA), longitudinal separation has been reduced to 5 minutes between aircraft following the same track.

When these trials end, PBCS standards will be introduced to continue to allow the application of both reduced lateral and longitudinal separation for aircraft that meet the Required Communication Performance (RCP) and Required Surveillance Performance (RSP) specifications.

How do I comply with PBCS standards?

First off, it’s already the case that operators need to be RNP4-approved to operate anywhere on the tracks between FL350-390 anyway.

But now in addition to that, to operate on the PBCS tracks between those levels you’ll need CPDLC capable of RCP240, and ADS-C capable of RSP180.

But watch out! Some aircraft do have ADS-C and CPDLC but have never demonstrated RCP or RSP, and have no statement of compliance (e.g. most Honeywell Primus aircraft and several early Boeing aircraft). These aircraft may struggle to get approval to operate in PBCS airspace. Which brings us neatly on to…

Do I need PBCS approval from my state of registry?

PBCS approval will differ depending on which country operators are from.

For UK operators, check the requirements here.

US operators will need to update their LOA for Data Link Communications (A056). The FAA have published a new guide, which tells operators exactly what they need to do to get this authorisation, namely:

  1. Submit an AFM Statement of Compliance for PBCS, showing exactly what data link communication systems you aircraft has, along with the selected performance
  2. Since July 2016, various oceanic FIRs have been collecting data on whether certain aircraft meet RSP and RCP criteria. You need to make sure your aircraft isn’t already listed as having failed to meet these criteria, by checking here: https://www.faa.gov/air_traffic/separation_standards/pbcs_monitoring/

What new codes do I need to put down on my flight plan?

  • FANS 1/A CPDLC equipped aircraft planning to operate in the NAT HLA shall insert the appropriate designator (J2, J3, J4, J5 and/or J7) in Item 10a of the flight plan.
  • FANS 1/A CPDLC RCP 240 compliant aircraft intending to operate in the NAT HLA shall insert the designator P2 in Item 10a of the flight plan.
  • FANS 1/A ADS-C compliant aircraft planning to operate in the NAT HLA shall insert the designator D1 in Item 10b of the flight plan.
  • FANS 1/A ADS-C RSP 180 compliant aircraft planning to operate in the NAT HLA shall insert SUR/RSP180 in Item 18 of the flight plan.
  • RNP 4 compliant aircraft planning to operate in the NAT HLA shall insert PBN/L1 in Item 18 of the flight plan.

If I’m not eligible for PBCS, where can I go? 

ATC may allow you to do either of the following, depending on how stressed/busy they are (i.e. decided on a ‘tactical basis’):

  • You can infringe on the daily PBCS tracks between FL350 – FL390 at only one point (including Oceanic Entry/Exit Point) i.e. cross but not join an NAT PBCS track
  • You can climb or descend through levels FL350 – FL390 on a PBCS track provided the climb or descent is continuous.

In their NAT OPS Bulletin 2018_001, ICAO have published a handy little picture to demonstrate this:

North Atlantic 2018 Operational Changes – Shanwick, Gander, Iceland, Santa Maria, New York – and the NAT HLA

We’ll use this page for NAT changes, including EGGX/Shanwick, CZQX/Gander, BIRD/Iceland, ENOB/Bodo, LPPO/Santa Maria, and KZWY/New York Oceanic East.

2018

2018 is off to a flying start again with NAT changes – these are the latest important changes. These are also published in the latest edition of NAT Doc 007, January 2018.

  • PBCS From March 29th 2018, PBCS is a requirement for the NAT Tracks between FL350-390 – RCP240 and RSP180. Read more about PBCS in our article, and check out the NAT Circle of Change for an easier graphical representation.

2017

Lots of important changes in 2017

  • SLOP – Offsetting is now mandatory. Choose 0, 1, or 2nm right of track. We think 1 or 2 is best. Consider the recent A380 story.
  • TCAS 7.1: From January 1st, 2017, TCAS 7.1 is required throughout the entire NAT region.
  • Cruising Level: Effective 2017, you no longer need to file an ICAO standard cruising level in NAT airspace.
  • Gross Nav Error:  is now defined as greater than 10nm (used to be 25nm)
  • Contingency Procedure: Published January 2017, a new turn-back (180) procedure is introduced – turn back to parallel previous track by 15nm.
  • Datalink Mandate Exemptions: Phase 2B of the Datalink mandate started on December 7, 2017 (FL350-390). Exempt: Radar airspace, Tango Routes, airspace north of 80N, and New York OCA.

2016

  • Confirm Assigned Route Introduced August 2016, you will see this message when you enter NAT airspace with datalink, and you should reply with the planned route in NAT airspace. Designed to catch errors.
  • NAT HLA The airspace formerly known as MNPS. Changed February 2016. NAT HLA = NAT High Level Airspace. Now includes Bodo Oceanic, and aircraft must be RNP 4 or RNP10. Previous MNPS approvals good through 2020.

2015

  • RLAT Started December 2015, spacing on the NAT Tracks reduced to “Half Track” (30nm) for 3 core tracks. RLAT=Reduced Lateral Separation Minima. Next phase (ie. all NAT Tracks 350-390) now planned for December 2017.
  • SLOP Offsetting right of track by 1nm or 2nm became Mandatory.

More NAT half-tracks are coming

Update Jan 23: The current phase of the trial for RLatSM Tracks will come to an end on March 29, when PBCS standards will be introduced for the NAT tracks. More info on that here.

Since Dec 2015, there have been three daily NAT tracks spaced by one-half degree between FL350-390. These are officially called ‘RLatSM Tracks’ (Reduced lateral separation minima), but we all just prefer to call them ‘Half-Tracks’.

Separating flights by one-half degree of latitude rather than the standard one degree means that aircraft can be separated laterally by 25nm, which helps improve the efficiency of North Atlantic operations.

In Jan 2018 the Half-Tracks will be expanded from the three that now run each day, first by one additional track and then (maybe) to all NAT Tracks between FL350-390 inclusive. Jan 4 is the earliest day that this might happen, but because they will be decided tactically, it will most likely be the first busy day after Jan 4.

If you want to operate on the RLatSM tracks, you’re going to need CPDLC, ADS-C, and RNP4; along with the other standard pre-requisites for operating in the NAT HLA between FL350-390: an HLA approval, TCAS 7.1, RVSM approval, two LRNS, and a working HF radio. To figure out where you are welcome on the NAT, depending on what equipment and training you have, check out our quick and dirty guide here.

One thing to be cautious of when using the half-degree tracks – most aircraft FMC’s truncate lat/long waypoints to a maximum of 7 characters, so it will often show up as the same waypoint whether you’re operating along whole or half degree waypoints. So when operating on the half-tracks, just remember to double-check the full 13-character representations of the lat/long waypoints when you enter them into the FMC.

For more details about the new RLatSM procedures, have a read of the UK AIC 087/2017 here.


					
		

NAT Expanded data link mandate

It’s time for everyone’s favourite topic – DATA LINK MANDATE! New things are happening on December 7th. Don’t worry, we’ll help.

Right Now, if you’re using the NAT tracks, between FL350-390, you’re mandated to use data link services. Simply put, you must be equipped with CPDLC and ADS-C (FANS 1/A ready and able).

On December 7th 2017, the data link mandate will expand to the entire ICAO NAT Region between FL350-390, with a few exceptions. We’ve got the image below showing you the area. White routes are exempt, as well as the grey border areas (we like the Big Fish).

Exemptions:
-Everything north of 80°North
-New York Oceanic East FIR (was previously all of NY Oceanic)
-Routes T9, T213, T13, T16, T25. (see: The Tango Routes)
-The Blue Spruce Routes (white lines)
-Areas that currently have radar, multilateration (is this a word?) and/or ADS-B. (the grey areas)
Note: If any of the NAT Tracks go into the grey areas, you won’t be exempt while on the tracks.

Be ready, January 30th, 2020, all of the NAT ICAO Region will have the Data Link Mandate, above FL290, including the Tango Routes as well as those little grey areas.

To figure out where you are welcome on the NAT, depending on what equipment and training you have, check out our quick and dirty guide here.

For more details about the datalink mandate, you can read the UK AIC in full here.

CYYR/Goose Bay closed – sticky runways

CYYR/Goose Bay was closed by the Canadian Department of National Defence on Nov 8, following the discovery of a problem with their runways. During snow removal operations over the past few days, crack sealant was found on vehicles after they were used on the runways. Specialists are en-route to Goose Bay to assess the situation.

Runway 08/26 has been completely closed, and Runway 16/34 has closed to all except Medevac flights, with a shortened Landing Distance Available of 7600 feet.

The Airport has said that emergency flights will be considered on a “case by case basis”. However, for now, carrying CYYR as an ETOPS alternate does not make sense.

Current Notams show the airport closure has been extended until 2359Z today, Nov 9, though that may still be extended further.

Greenbacks and Greenland – $3000 to file as an alternate

Trans-atlantic operators who have been putting RALT/BGBW on their flight plans have been receiving hefty invoices post-flight.

BGBW/Narsarsuaq is a popular airport to use in flight planning as an emergency divert and for ETOPS, as it’s perfectly positioned right in the middle of the big empty chunk of nothing that exists between the east coast of Canada and Iceland.

BGBW is open Mon-Sat 11-20z (8am-5pm local time). It’s completely closed on Sundays and on holidays.

So if you file a flight plan with RALT/BGBW from Mon-Sat 11-20z, you won’t get charged.

But outside these hours, you will get charged. It gets slightly complicated here: the charges in the box below apply when they stay open for you to use as an ETOPS alternate at any time that they are closed, but there’s an extra 10% charge on top of that for any time they are closed and fast asleep in bed, which is between 00-08z (9pm-5am local time). Got it?

Important to note: these get charged even if you don’t actually divert to BGBW. To save you from having to Google it yourself, 15,870 Danish Krone equates to $2485 USD!

If you want BGBW to stay open for you to use as an ETOPS alternate, you need to put RALT/BGBW in your flight plan – they’ll see it, and will stay open for at the times you need. But bear in mind that if they’re closed already at the time you file your flight plan, they won’t see it! So they prefer you to do it properly and arrange everything in advance by email.

If you get an invoice from a company called Global Aviation Data A/S, unfortunately it’s not a scam email – they are the guys who work with Greenland Airports to collect the monies owed when operators request airports like BGBW to stay open for them.

NAT Airspace Closures

Update 18th Oct: No more events are planned at this time. However, we will keep this page updated with the latest news as we get it.

 

Sections of NAT airspace are set to close on various different dates in October. This is all due to U.S. and NATO joint military exercise that’s going on, called Formidable Shield, which will mean huge chucks of airspace will be closed to civil ops for many hours.

The basics for each event are the same:

  • Airspace closed, SFC-UNL.
  • Aircraft capable of flying in MNPS airspace will have to keep at least 30nm away from the area, other aircraft will need to keep 60nm away.

 

Event 1 Happened on 25th Sep. 

 

Event 2 Happened on 7th Oct.

 

Event 4Happened on 15th Oct. (Yes, Event 4 happened before Event 3 – just to confuse us!)

 

Event 3 Happened on 17th Oct.
