the 25 nautical mile (NM) reduced lateral separation minimum (RLatSM). After a short wait, our cockpit chime rings and our oceanic clearance is ready to view. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Want to talk to us? For our flight to London, AeroSavvy 105s dispatcher requests track Uniform in our flight plan. Loop Its easier than posting a Facebook status! The research paper, however, and associated media fanfare, has shakier foundations. Lets see why this is not the case. There was no fanfare or fireworks, but last Tuesday was a significant day in the history of transatlantic air travel. Daily updates for each direction allow for routing around weather systems and tracking of favourable tailwinds to improve efficiency. Latest Analysis| For example, if an aircraft can no longer maintain the speed or altitude it was assigned, the aircraft can move off the track route and fly parallel to its track, but well away from other aircraft. The concept of free-routing on the NAT is one that airlines in particular have been keen to see for a long time: the ability to decide their own routes, unconstrained by an . S The next big consideration is turbulence. It was a perfect time to test a new way to control air traffic across the ocean, one that uses less fuel and emits less carbon dioxide. F The difference? 16 March 2021. R You might consider an article on North American east and west and north feeder routes that join feet wet Atlantic routes or Polar routes. Check out this amazing visualization produced by NATS (National Air Traffic Services), the main air traffic control provider in the UK. Its easy to use and looks like a paper tower dispenser! Atlantic Ocean Westbound Tracks. WEST LVLS 310 320 330 340 350 360 370 380 390. I really appreciate your nice comments! they also found that when an eastbound track is very far away from the route . D NA Radar| Eastern Satellite| North Atlantic Tracks for the eastbound crossing on the evening of May 4, 2006. It traveled from New York's JFK to London's Heathrow in 4 hours, 56 minutes overnight Saturday. This allows the ATC agency to know what the route preferences are of the bulk of the North Atlantic traffic. - Customs available 24 hours daily. 6 HR | The Pacific is even larger than the Atlantic, and I believe the Japan-California routes would be very busy as well. The Oceanic Controllers then calculate the required separation distances between aircraft and issue clearances to the pilots. Help Center; Community; Blog 18 z Since the background to this article is considering the benefits of not having to follow prescribed NAT Tracks, the key question is where has most efficiency been lost on this flight? In the example above, Track C is the RLatSM track. In the case of HF reports, each aircraft operates using SELCAL: selective calling. The GC path is again shown in white. FL390 Ken, you might help clarify a little mystery for me. Turbulence forecast for North Atlantic Eastbound tracks valid on 2023 03 01 at 00 UTC for FL280-430. Turbulence and thundestorm historical data of the North Atlantic Ocean. The efficiency figure of 16.4% is created by dividing the air distance between LHR-JFK by additional distance flown on the least efficient eastbound NAT Track (2,997nm/503nm ~ 16.4%). . Before the COVID-19 pandemic, almost 2,000 airliners safely crossed the North Atlantic . Westward tracks are named incrementally from the beginning of the alphabet (A,B,C. Views: 13,129. They ensure aircraft are separated over the ocean, where 06 z Question for us? North Atlantic Track system (NATs) - Routes across the pond. North Atlantic Tracks, FANS 1/A+ required in all MNPS airspace FL290 and above required by, Equipment required to use designated ADS-C CPDLC Track, J5 - CPDLC FANS 1/A SATCOM (INMARSAT) and/or, Item 10b ( required in addition to equipment from item 10a), The next phase Phase 2b of the NAT DLM commences. Why those times? On a busy day, aircraft are spaced approximately 10 minutes apart. He currently frustrates air traffic controllers in the US, Asia, and Europe as a Boeing 757 and 767 captain for a package express airline. Europe loop| 340 350 360 370 380 390 400. Therefore, we have to disregard these higher numbers entirely. Thats a good point. Currently airliners emit 2.7% of the carbon dioxide in the atmosphere. Each route is uniquely identified by a letter of the alphabet: Points along the route are identified by named waypoints (or fixes) and by the crossing of degrees of latitude and longitude (such as54/40, indicating 54N latitude, 40W longitude). FANS 1/A+ required in all Minimum Navigation Performance Standards (MNPS) airspace FL350-FL390, inclusive required by, FL 350 to FL 390 (inclusive) all tracks within the Every day, from 0100z - 0800z (8 pm - 3 am EST) hundreds of airliners fly eastbound from North America to Europe. Conflict solved. or waivers will be permitted, due Atlantic AVN Loop, Canada - Obs/Tafs Sat links Radar links Notams 4 Day Model, Atlantic Sigmets [2], The specific routing of the tracks is dictated based on a number of factors, the most important being the jetstreamaircraft going from North America to Europe experience tailwinds caused by the jetstream. The following flight level allocation scheme (FLAS) should be used by operators for flight planning purposes: May be flight planned for both eastbound and westbound non-RVSM certified aircraft FL390 Q . Loop Westbound tracks are labeled A, B, C, D, etc. Im flattered that my article was your first cup of joe reading! North Atlantic Turbulence Westbound Tracks. This does not take winds into account, so to find the best wind route, we must add wind from the forecast for FL390 for our time of flight. O Each route is uniquely identified by a letter of the alphabet. Any NOTAMs pertaining to these tracks (waypoint changes, procedures) will be found by searching the ARTCC NOTAMs under Shanwick Center (EGGX), Gander Center (CZQX), Boston Center (KZBW) and New York Center (KZNY). The 25 NM lateral separation minimum will be implemented by applying 1/2 degree track spacing between three core NAT Organized Track System (OTS) tracks (NAT Tracks). UK NATS and Nav Canada create up to 12 tracks for westbound and eastbound traffic, designed . I would like to know what routes are followed from europe to south america and viceversa. Traveling from Europe to America: Westbound track. Very ocasionally, a track one north or one south is given by ATC. Therefore, the winds shown are those at FL390. The NAT region was the first to implement reduced vertical separation (RVSM), in March 1997, and subsequent improvements in surveillance (ADS-B, ADS-C), and communications (CPDLC), have led to lateral separation improvement from 60nm to 19nm, and longitudinal from 80nm (or 10 minutes) to as low as 14nm in addition to the altitude separation reduction from 2,000 to 1,000 feet. Each aircraft with HF has its ownSelCal code assigned to it. North Atlantic Tracks are calculated and published by Shanwick Centre (EGGX) at Prestwick Centre in Ayrshire, Scotland and Gander Centre (CZQX) in Newfoundland and Labrador, Canada. Source: turbli's historical database, built from the daily forecasts provided by NOAA and the UK Met Office. After another SelCal check, the crew will have an hour of peace and quiet before things get busy approaching London. NAT - FL 390 Westbound OTS (subject to eastbounds). This is not what happens in reality, by any stretch. Whole Atlantic / Thank you very much for an incredible website. . There is no "tend to fly northerly tracks" westbound and "more typically southerly tracks" eastbound. Any NOTAMs pertaining to these tracks (waypoint changes, procedures) will be found by searching the ARTCC NOTAMs under Shanwick Center (EGGX), Gander Center (CZQX), Boston Center (KZBW) and New York Center (KZNY). 15 z The polar jet stream can also be thought of as the "storm track", as it is associated with the powerful low-pressure systems we experience, usually in winter. M Canada|, Satellites- Tracks to Europe use the jetstream to their advantage by routing along the strongest tailwinds. In a domestic ATC environment, the approximate sequence of events goes like this (callsigns dropped from some calls for clarity): Controller (thought): Hmmm, Delta and Speedbird are getting a little close. | Figure 1(b) shows all eastbound tracks between JFK and LHR on the 3 December, 2019. North Atlantic (NAT) air traffic contributes to two major westbound and eastbound alternating flows. FL300-FL380 / 250 MB TURB No special authorization or LOA is required to operate in RLatSM. The long-awaited and much discussed scenario on the North Atlantic finally happened this week: No published NAT Tracks, with all aircraft on Random Routes. FL450 If the airspace permits it, you should be "randomly" offsetting, especially across the North Atlantic. The operators relay information between air traffic controllers and pilots. Im wondering if theres a way for me to determine ahead of time if the trafic will be overhead or out of my field of view. 25 NM lateral separation will be applied between flight level 350-390 (inclusive). The three North Atlantic Routes used for Concorde were as below. Also, pilots on North Atlantic Tracks are required to inform air traffic control of any deviations in altitude or speed necessitated by avoiding weather, such as thunderstorms or turbulence. Aircraft VHF radios have a very short range, so they are of little useover the ocean. Before we can fly across the Atlantic, we need to select a track (or route). Well written article for the aviation enthusiast, aviation professional and general public alike. Facilities with a call sign suffix of Radio (like Gander Radio) are typically HF radio services staffed by professional operators. 15 z [citation needed], Additionally from 10 June 2004 the strategic lateral offset procedure (SLOP) was introduced to the North Atlantic airspace to reduce the risk of mid-air collision by spreading out aircraft laterally. If the aircraft is equipped with automatic dependent surveillance, (ADS-C & ADS-B), voice position reports on HF are no longer necessary, as automatic reports are downlinked to the Oceanic Control Centre. Update: August 2019 - you can now "MicroSLOP" in the NAT. NAT - FL 340 . However, its a bridge too far to assume that just because surveillance is good, we can start treating the Air Traffic Control of NAT aircraft as if it were somewhere in the centre of Europe. Every day, from 0100z 0800z (8 pm 3 am EST) hundreds of airliners fly eastbound from North America to Europe. Current Turbulence Sigmets Click on image to access plots Current Turbulence Aircraft Reports Click on region names to access plots Graphical Turbulence Guidance Click on image to access GTG plots Page loaded: 00:40 UTC | 04:40 PM Pacific | 05:40 PM Mountain | 06:40 PM Central | 07:40 PM Eastern ADVISORIES. 200 MB The radio operators are based just to the north of Shannon but the ATC service is provided by the Scottish Centre at Prestwick. ADS and CPDLC can send data over SatCom (satellite), VHF, and HF radio so they work great over the ocean. Atlantic Satellites North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), is a structured set of transatlantic flight routes that stretch from the eastern North America to western Europe across the Atlantic Ocean, within the North Atlantic airspace region. Before we can fly across the Atlantic, we need to select a track (or route). D. MCT: Minimum Cost Track. Fly UK VA - The UK's leading Flight Simulation Virtual Airline | Fly UK . The operator will give us a quick SelCal check to make sure our chime rings in the cockpit: Heres the transcript ofthe audio clip: For Atlantic crossings, the route clearance covers the beginning and ending domestic portions of the flight. 0000Z Sig Wx| FL380 0300 0700 Westbound (ODL, on and to the North of the North datum line). The paper shows these graphs, with the eastbound plot on the right: From an operational perspective, however, the promise of 232km (125nm) average route savings, and 16.4% increases in efficiency do not ring true. We are an industry founded on innovation and ingenuity, and we should be looking for every opportunity to do something more than just shave a few dollars off a route cost. I am sure you can see the pattern: the NATs! The chart below can be used to help decode the information. What confounds me is that on certain days, there will be lot of air trafic in my vicinity, but other days, these same flights will be about 100 lateral kilometers to the north or south of my position. Europe Surface V FOXXE LOACH 57/50 58/40 58/30 57/20 SUNOT KESIX. FL450 Westbound In the Reading University report, this is called the OFW: Optimized for Wind Route. The Oceanic Controllers then calculate the required separation distances between aircraft and issue clearances to the pilots. .. am sure your hands are even better for control yokes. I fly often between EWR/JFK and Europe/Near East, so you answered many questions. Its like listening toa distant AM radio station at night; lots of static. OTS tracks separated using RLatSM will be established by publishing one track defined by 1/2 degree waypoints (e.g. Almost all of the time, the requested track is granted, albeit with potentially a lower level (or higher) than requested. RAC 11.20.4 (V), (VI) AND (VII): TO READ: PRINS CHRISTIAN SUND-59N 50W-ALTOD(FL290-600)-PRAWN-NAIN, PRINS CHRISTIAN SUND-59N 50W-CUDDY(FL290-600)-PORGY-, PRINS CHRISTIAN SUND-58N 50W-HOIST-GOOSE VOR. In essence, the procedure demands that aircraft in North Atlantic airspace fly track centreline or one or two nautical mile offsets to the right of centreline only. You are appreciated!! Oceanic ATC, even with this additional surveillance, remains more of a procedural environment and separation standards cannot yet drop. North-Atlantic Weather Map. ofNorth Americato westernEuropeacross theAtlantic Ocean. However, consider further that we looked at four different types of efficiency loss: flight planning constraints, avoiding turbulence, the NAT Tracks requirement, and tactical routing by ATC. Therefore, most operators choose to file a flight plan on a NAT Track. Email is always easiest: a good one to use is messages@ops.group. Atlantic Ocean Eastbound Tracks. This is often also where the core efficient NAT Track Xray or Zulu lies these days. AeroSavvy is written by Ken Hoke. Airplanes fly the routes they do over the Atlantic because they are the fastest and most efficient. [citation needed], A typical routing would be: DCT KONAN UL607 EVRIN DCT MALOT/M081F350 DCT 53N020W 52N030W NATA JOOPY/N0462F360 N276C TUSKY DCT PLYMM. 4). Because thats when most passengers want to fly these routes. Weve got surveillance nailed its basically the same as radar, now that the full complement of Aireon ADS-B satellites are up and running, complementing the ADS-C coverage already in place. Latest Analysis| As a former flight dispatcher who dispatched B767s over the North Atlantic and a current manager in the aviation services industry I found your article to be very informative and full of great information. Traveling from America to Europe: Eastbound track. The first topic is a performance assessment study of the flight operations in the North Atlantic Organized Track System. The east Atlantic region that AeroSavvy 105 will overfly is called the Shanwick Oceanic Control Area. Looking like a matrix of skyways across the ocean, the North Atlantic Organized Track System (OTS) is a set of virtual aerial highways that are created and managed by the bordering air navigation . | Europe 24H I spent 30 years controlling the Notth Atlantic and running visits for aircrew and operational personnel. One route in particular that seems to be doomed for a more turbulent future is New York-London (and vice-versa), thanks to acceleration of the jet stream and clear-air turbulence expected to result from it. N The first RLAT tracks were published in December 2015. FL340 It reduces the risk of collision for non-normal events such as operational altitude deviation errors and turbulence induced altitude deviations. 0000Z Sig Wx| Below is an example of a NAT track message, published on the 1st of May detailing the tracks valid for the 2nd of May. | 12 HR| Eastbound OTS (subject to westbounds). |, 500mb Analysis | We made it across the pond! Its nice to have a hard copy to reference. C. MTT: Minimum Time Track. There are also daily tracks published for flights between Australia and the Middle East & Southeast Asia. IR+Vis| | The second phase, commencing These heavily travelled routes are used by aircraft flying between North America and Europe, operating between the altitudes of 29,000 and 41,000ft (8,800 and 12,500m) inclusive. Westbound (OTS). Same logic as NATs? After considering the factors noted in Planning the North Atlantic Routes above, and . What a nice article !!! Control the animation using the slide bar found beneath the weather map. The same is true of the North Atlantic; there is no radar coverage for much of that area How, then, do so many flights navigate safely, all day, every day from Europe to North America and back again? Icing & Turb In the old days, pilots reported their position by HF radio every 10 longitude. This site uses Akismet to reduce spam. Starting from . Some experts are concerned that turbulence might become more common due to a warming planet: A 2013 report found that turbulence strength over the North Atlantic flight corridor could increase by . This route equates to the MFT (Minimum Fuel Track) in flight planning systems, and in our case here, also the MTT (Minimum Time Track). A. In essence, the procedure demands that aircraft in North Atlantic airspace fly track centreline or one or two . However, authorizations are required for the minimum surveillance and navigation requirements(RNP4, FANS 1/A) necessary to operate in RLatSM. I have always been curious about the routing over the north Atlantic. NHC| Note - Item 18 is a different/new requirement over just the CPDLC tracks. We are not currently flight planning to minimise emissions we flight plan to minimse cost. | 200 MB, Atlantic Significant Weather Charts This website uses cookies to ensure you get the best experience, VENER 5430/20 5430/30 5430/40 5330/50 PELTU, TUDEP 52/50 55/40 56/30 56/20 PIKIL SOVED, NICSO 48/50 50/40 52/30 53/20 MALOT GISTI, ALLRY 51/50 54/40 55/30 55/20 RESNO NETKI, PORTI 47/50 49/40 51/30 52/20 LIMRI XETBO, BUDAR 5030/50 5330/40 5430/30 5430/20 VENER KOKIB, SUPRY 46/50 48/40 50/30 51/20 DINIM ELSOX, ELSIR 50/50 53/40 54/30 54/20 DOGAL BEXET, RAFIN 45/50 47/40 49/30 50/20 SOMAX ATSUR, DOVEY 42/60 44/50 46/40 48/30 49/20 BEDRA NASBA, JOOPY 49/50 52/40 53/30 53/20 MALOT GISTI, NICSO 48/50 51/40 52/30 52/20 LIMRI XETBO, MUNEY 41/60 44/50 47/40 50/30 51/20 DINIM ELSOX, 36/60 40/50 44/40 47/30 48/20 48/15 OMOKO GUNSO. On a typical flight, we wont need to talk to anyone again until we approach 30 west longitude. FL 350 to FL 390 (inclusive) all tracks within the North Atlantic Tracks Flights equipped with and prepared to operate FANS 1/A (or equivalent) CPDLC and ADS-C data link sys. A reduction in volume goes hand in hand with a reduction in complexity from an ATC perspective. H Then SUNOT-KESIX are the entry points into Europe for that track. MeteoStar Atlantic Loop applicability and within NAT organized track system (OTS) ranging from Aircraft must report in as they cross various waypoints along each track, their anticipated crossing time of the next waypoint and the waypoint after that. 55 degrees 30 minutes North Latitude/20 degrees West Longitude). If you've ever watched a placid thread of rising . Random routeclearances are issued the same way as trackclearances. (From an Army King Pilot). H NA Sat| : Did you know that Concorde did not travel on the North Atlantic Tracks? Turbulence. X CPDLC and ADS digital communication is spreading rapidly over many countries. West Atlantic Sigmets The North Atlantic Organised Track System (NAT-OTS) is known in shorthand as the North Atlantic Tracks, or even as NATs. Obs/Tafs| North Atlantic Tracks (NAT) are trans-Atlantic routes that stretch from the northeast of North America to western Europe across the Atlantic Ocean. . 1000 1129 Westbound (subject to eastbounds). Coefficients are determined by averaging near-neighbour historical track data, with 'near' determined optimally by using . For this flight, the requested track was not available at FL390 (because of other traffic ahead). 0600z | And therefore, removing the NAT Organized Track Structure for high volumes of traffic is a big challenge. Departure to destination in shortest possible time. Volcanic Ash Contingency Plan - European and North Atlantic Regions (EUR/NAT VACP, EUR Doc 019, NAT Doc 006 Part II) - 2.0.1 Corrigendum (June 2021) 2329 KB 2021-10-14 12:00 AM Email us at messages@ops.group. Eastbound OTS (subject to westbounds). Info. North Atlantic Tracks (NATS), officially titled the North Atlantic Organised Track System (NAT-OTS), is a structured set of transatlantic flight routes that stretch from the northeast of North America to western Europe across the Atlantic Ocean. What if a flight needs to go the opposite direction of the track system? Listening to Gander and New York OAC, on HF, I wish I could get waypoints names and coordinates over the Atlantic, thank you. Prior to departure, the aircraft will then contact the Oceanic Center controller before entering oceanic airspace and request the track giving the estimated time of arrival at the entry point. U Euro Control Validator | The six tracks are labelled from A to F and lie predominantly North of the GC path to avoid the prevailing jet stream air currents. Gander Radio, Gander Radio, AeroSavvy 105 on five-six, https://aerosavvy.com/wp-content/uploads/2016/02/Gander-SELCAL-Checkshort.mp3, How Pilots Communicate In Other Countries, https://aerosavvy.com/great-circle-routes/, Aircraft tail number: N10ASV (the pride of the fleet!). | Europe 24H Again, real world analysis of actual flights with the full compendium of information as to what caused the ineffciencies would give the most insight, and this is what we will hopefully see from NATS and Nav Canada as a result of the OTS NIL experiment. [5], In 2018, 500,000 flights went through; annual fuel savings are expected around 38,800t (85,500,000lb), and may improve later. The downside is that transmissions aresometimes difficult to hear. FL340 B The North Atlantic is the busiest piece of oceanic airspace in the world, but we went from handling up to 1,700 movements a day in 2019 to as few 200 on some days in 2020. . The narrative in the majority of recent reports about the North Atlantic tell us that because we now have ADS-B satellites, and thereby excellent surveillance, this changes the entire landscape, and allows for the disbanding of NAT Tracks. Closer analysis shows that at least some of the assumptions in the report to be fundamentally flawed. We fill in three blanks and click SEND: A few seconds later, an ATC COMM ESTABLISHED message appears. Without published tracks to assist in separation, the burden on the controller is increased but the lower traffic levels mean it can be safely managed. Click on the Corresponding Letter to See the Current SIGMET North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), is a structured set of transatlantic flight routes that stretch from the northeast of North America to western Europe across the Atlantic Ocean. [citation needed], A random route must have a waypoint every 10 degrees of longitude. Storm in the Cockpit: Tales of Conflict and Clashes, The Lowdown on AUSOTS: Australian Flex Tracks. There are several standard, published airways connecting South America and Europe. A few minutes before reaching LIMRI and XETBO, our oceanic exit points, AeroSavvy 105 will receive a CPDLC message like the one below. Facilities with a call sign suffix of Center (Gander Center), usually transmit on VHF radios. Non-equipped flights that file STS/FFR, HOSP, HUM, MEDEVAC SAR or STATE are allowed but may not receive ATC clearance as filed. See also the section, What are NAT Half Tracks?, below for more information on the half track system. In this case, there are five tracks. Thats exciting. Capacity is increased as NATS expects 16% more flights by 2025, while predicting that 10% of traffic will use the Organized Track System in the coming years, down from 38% today[when?]. Ill climb the Delta. Each letter corresponds to an audio tone frequency. About. But for aircraft operators, we have to consider whether saving 100 kgs in fuel results in being 10 mins late to stand, or makes us overfly a much more expensive country, or miss a curfew time at the airport. 05: Published NAT Tracks. 24.2 upper left), while the. If a flight cant utilize the tracks, it can fly a Random Route. Random routes are carefully planned by dispatchers or pilots andmust be approved by air traffic control. [4], At the end of March 2019, Nav Canada and the UK's National Air Traffic Services (NATS) activated the Aireon space-based ADS-B relayed every few seconds by 450nmi (830km) high Iridium satellites to air traffic control centers. But this overlooks a key point: its not a surveillance problem, its a comms problem. 12 HR | North Atlantic Tracks for the eastbound crossing on the evening of May 4, 2006. The tones triggera chime in the cockpit to alert the crew they are needed on the frequency. Keep them coming! Turbulence areas are indicated with dashed red lines. 06: Closest NAT Track to Preferred Route. [citation needed]. NORTH ATLANTIC TRACKS - NAT A and Z TRACKS North American Routings-. from North) to the counterclockwisefrom East as shown in Fig. IR+Vis| - Open 24 hours. (Image courtesy of eWAS Pilot) . Y | Great read. Commencing February 7, 2013, two core tracks, under Nav Canadas area of This is good for reducing fuel burn and flight time. A position report provides an aircrafts location, speed, and altitude so the controller can build a 3D picture of all the traffic. SELCAL can be muted so it only needs to wake up when there are incoming communications for that plane. NorthAtlantic WeatherMaps, Models, and everything else you need. Have you ever wondered how pilots navigate and communicate during the journey? | Headline: New York-London journeys could be cut by 21 minutes. There are normally 8-10 NAT Tracks eastbound. I | Performance-Based Communication and Surveillance is being introduced to reduce lateral and longitudinal separation for aircraft that meet the Required Communication Performance (RCP) and Required Surveillance Performance (RSP) specifications. The MTT and MFT will go through Russia [where navigation fees are much higher]. capabilities will be put in the outer tracks, which will add to flight That least efficient NAT Track (which will usually be Track Zulu in non-Covid ops for an eastbound flight) is normally a southerly Caribbean area route intended for traffic departing places like Miami, the Bahamas, or even Trinidad and Tobago. Newfoundland Maps ADS (Automatic Dependent Surveillance)is the system that makes our position reports for us. NATS always puts out great stuff! Logging on to CPDLC and ADS is a super easy. When radio operators need to contact an aircraft, theytransmit the aircrafts SelCaltones (they sound like telephone touch-tones). The printer uses a thermal print head and rolls of heat sensitivepaper. L (as far as M if necessary, omitting I), where A is the northernmost track, and eastbound tracks (valid from 01:00 UTC to 08:00 UTC at 30W) are indicated by the letters Z,Y,X,W etc. Our CPDLC and ADS will automatically log off Ganders system and logon to Shanwick like magic! This page was last edited on 1 November 2022, at 21:11. Storms are also possible in the red areas which also indicate the possibility of turbulence. About 30 minutes before a flight departs, the crew contacts air traffic control to receivea route clearance. [citation needed], Since 2017, aircraft can plan any flight level in the NAT HLA (high level airspace), with no need to follow ICAO standard cruising levels.[3]. R The MCT stays on the North Pacific in Oakland and Fukuoka airspace. W At 15W, the flight is under radar coverage from Shannon, and was cleared direct to the Strumble (STU) beacon in Wales (which was the original planned Top of Descent).
