There are four track calculation options available to most aircraft dispatchers and flight planing systems: A. MDT: Minimum Distance Track. The media, and even our own industry news coverage, would have us believe that somehow weve just stumbled onto some preternatural scheme of harnessing the power of the wind, to spirit our hulking lumps of metal across the pond. north atlantic tracks map. About an hour after departure its time to start thinking about our oceanic clearance. | | Westbound OTS (subject to eastbounds). You must use fixed 1/2 degree latitude points at every 10 degrees of longitude from Oceanic Entry Point to Oceanic Exit Point. A random route must have a waypoint every 10 degrees of longitude. 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 overlay of tracks that may be tangential to their flight-planning whims. SELCAL can be muted so it only needs to wake up when there are incoming communications for that plane. Since July 2016, various oceanic FIRs have been collecting data on whether certain aircraft meet RSP and RCP criteria. They are aligned in such a way as to minimize any head winds and maximize tail winds impact on the aircraft. Flight Level*: Shanwick/Gander may exchange on a tactical basis during OTS periods. The routes dont change daily like over the North Atlantic. Check out this amazing visualization produced by NATS (National Air Traffic Services), the main air traffic control provider in the UK. Very ocasionally, a track one north or one south is given by ATC. 29 MAY 09:01 2014 UNTIL 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. AeroSavvy is written by Ken Hoke. Europe Surface Each track is labeled by a letter to make it easy to reference on a flight plan. It allowscontrollers to request and receive digital reports from the aircrafts navigation system without bothering the crew. Flights between North America and Europe often fly right over your house! 12 HR | 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%). 1800z In the Reading University report, this is called the OFW: Optimized for Wind Route. Therefore, most operators choose to file a flight plan on a NAT Track. 0000Z Sig Wx| Well look at three things in this article . Atlantic Ocean Westbound Tracks. Satellite: view. Dont bother checking a map of Ireland or Scotland; you wont find it. At first glance, it might appear that the most logical route is the best wind route, in other words, the track across the ocean where we can take maxium advantage of the jet stream. A note from the AeroSavvy Barrister Learn about great circle routes: https://aerosavvy.com/great-circle-routes/. Europe Surface Atlantic Ocean. D Thanks for reading and safe travels! NAT - FL 390 There was no fanfare or fireworks, but last Tuesday was a significant day in the history of transatlantic air travel. [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]. The Pacific is even larger than the Atlantic, and I believe the Japan-California routes would be very busy as well. Based in Christchurch, New Zealand. This article has been written to give the reader a general idea of the procedures used on a trans-Atlantic flight. For Atlantic crossings, the route clearance covers the beginning and ending domestic portions of the flight. You must fly a straight line from that point to the next 10 degree longitude line. Mapped Ocean Tracks are available to subscribers with a Gold or Business account. I fly often between EWR/JFK and Europe/Near East, so you answered many questions. | Once airborne and enroute, about an hour from the Oceanic Entry Point at 50W, the crew will request their Oceanic Clearance from Gander, as per this flight plan route. M Daily updates for each direction allow for routing around weather systems and tracking of favourable tailwinds to improve efficiency. 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. This site uses Akismet to reduce spam. Since they cant see the aircraft, controllers rely on pilots to report their position at regular intervals. Almost all of the time, the requested track is granted, albeit with potentially a lower level (or higher) than requested. At 30 West, well switch over to Shanwick Oceanic Control, which raises the question: Where the heck is Shanwick? Click onthe track message image to see how it looks. Captain Hoke, 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. | 12 HR| You might consider an article on North American east and west and north feeder routes that join feet wet Atlantic routes or Polar routes. The MCT stays on the North Pacific in Oakland and Fukuoka airspace. Aviation text messaging without the LOLz & . Random route aircraft which join or leave an outer track of the OTS must be CPDLC/ADS-C equipped to operate at levels from FL350 to FL390 while on the OTS segment of the route. from North) to the counterclockwisefrom East as shown in Fig. It can take anywhere from a few minutes to an hour to receive an oceanic clearance from Gander. 36 HR| (From an Army King Pilot). The first RLAT tracks were published in December 2015. Controller: Delta 63, roger, turn right 10 degrees due traffic. To propagate tracks we use the means and variances of latitudinal and longitudinal displacements and model the remaining anomalies as autoregressive. Click on the Corresponding Letter to See the Current SIGMET They ensure aircraft are separated over the ocean, where They ensure aircraft are separated over the ocean, where there is little radar coverage. T Before we can fly across the Atlantic, we need to select a track (or route). The operator will give us a quick SelCal check to make sure our chime rings in the cockpit: Heres the transcript ofthe audio clip: 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). 1200Z Sig Wx| 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? Propelled by the jet stream, Flight BA112 topped a ground speed of 800 mph, by one expert's estimate. North Atlantic Tracks - Last updated at 2023/02/28 08:15 GMT; The following are active North Atlantic Tracks issued by Shanwick Center (EGGX) and Gander Center (CZQX). Contingency plans exist within the North Atlantic Track system to account for any operational issues that occur. The hardest thing in life is knowing what you want. 00 z Great read. West Atlantic Sigmets Phase 2B of North Atlantic (NAT) Data Link Mandate (DLM) coming soon, see below, FAACHARTS FR Enroute Aeronautical Charts and Planning, AIC 18/15 regarding The east Atlantic region that AeroSavvy 105 will overfly is called the Shanwick Oceanic Control Area. Wow,,,what a nice explination about NATsAs a airlines pilot, it is a really well understandable & easy one Thanks. 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?]. Departure to destination with lowest possible fuel burn. Half tracks are designed to increase aircraft density by allowing closer horizontal and lateral spacing of aircraft. Westbound General. NHC| We are not currently flight planning to minimise emissions we flight plan to minimse cost. Good luck with your interview! . Whole Atlantic / Using the track message above, I highlighted and labeled the days tracks on a North Atlantic plotting chart. ADS and CPDLC can send data over SatCom (satellite), VHF, and HF radio so they work great over the ocean. On this Wikipedia the language links are at the top of the page across from the article title. Surface Winds Model Whole Atlantic / Some routes are famously turbulent, but only during certain times of year. 500 MB Left is for losers - don't SLOP left of track. 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. Administration of the area is a joint venture that began in 1966: HF communications are based in Shannon, Ireland, and the air traffic controllers are located in Prestwick, Scotland. B | 12 HR| 1200z | 0600z | Very interesting and informative post, Ken. 18 z SIGWX | I really appreciate your comments, especially from a dispatcher! Pray tell. Currently airliners emit 2.7% of the carbon dioxide in the atmosphere. 2230 0059 Westbound (avoiding OTS). 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. North Atlantic Tracks are published by Shanwick Centre (EGGX) and Gander Centre (CZQX), in consultation with other adjacent air traffic control agencies and airlines. Y Its no different on the NAT. When we are issued an oceanic clearance, the clearance is for a specific speed and altitude.

Tracks to Europe use the jetstream to their advantage by routing along the strongest tailwinds. The shortest distance between JFK and LHR. Email is always easiest: a good one to use is messages@ops.group. Oceanic boundary points for the NAT Tracks are along the FIR boundary of Gander on the west side, and Shanwick on the east side. click for more flight level/times, North Atlantic Turbulence It is important to know that theadjacent tracks to the RLatSM track are also subject to the same equipment conditions required forRLatSM. Satellites- Info. This results in much more efficiency by reducing fuel burn and flight time. They ensure aircraft are separated over the ocean, where there is little radar coverage. Before the COVID-19 pandemic, almost 2,000 airliners safely crossed the North Atlantic . Europe loop| The first topic is a performance assessment study of the flight operations in the North Atlantic Organized Track System. 03 z 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. But this overlooks a key point: its not a surveillance problem, its a comms problem. Europe IR| The report itself makes the flaw clear here: Taking the results for an airspeed of 240 m s1 and averaging savings in air distance between the most efficient ATM track and the OFW route across all 91 days of winter 20192020 for flights from JFK to LHR, gives an air distance saving of 37 km, but the saving for the least efficient ATM track is over 931 km. | No exemptions or waivers will be permitted, due In this case, there are five tracks. to congestion of these tracks, and aircraft wanting to use this airspace The guidance was part of a number of changes [1] that were contained in a revised 2017 edition of NAT Doc 007:North Atlantic Airspace and Operations Manual [2] The video shows a railway platform somewhere in Mumbai with a huge crowd of passengers. I believe FlightRadar24 and similar apps will display the current tracks for you. V These tracks are given designators like Alpha, Bravo, Charlie, etc. About; Features; Apps; Browser Extension; Support. Each route is uniquely identified by a letter of the alphabet. The sky fell on me with the crew not getting clearance from Euro part and last minute fire fighting from my colleagues to set things right !!! D. MCT: Minimum Cost Track. Cargo flights often fly across the Atlantic at times when the tracks are flowing in the opposite direction, so they fly random routes. On 12 November 2015, a new procedure allowing for reduced lateral separation minima (RLAT) was introduced. ], Gander, AeroSavvy 105, SelCal OK, over. The second phase, commencing Thus, crew members need not devote their attention to continuous radio listening. NAT SN (Sierra November) - Normally used for Eastbound Concordes flights. It traveled from New York's JFK to London's Heathrow in 4 hours, 56 minutes overnight Saturday. Westbound departures typically leave Europe between early morning to late afternoon and arrive in North America from early afternoon to late evening. 06 z Surface Precip Model 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. That should get you started! Icing 6 HR This is often also where the core efficient NAT Track Xray or Zulu lies these days. Air traffic controllers responsible for the Shanwick flight information region (FIR) are based at the Shanwick Oceanic Control Centre at Prestwick Centre in Ayrshire, Scotland. Its easy to use and looks like a paper tower dispenser! Hello Haps, H . over North Atlantic Ocean to maximize its tail wind (Fig. 0600Z Sig Wx| The research paper, however, and associated media fanfare, has shakier foundations. Turbulence forecast for North Atlantic Eastbound tracks valid on 2023 03 01 at 00 UTC for FL280-430. 300 MB I imagine quite a few air crews dont realize the origin of the term Shanwick.. 6 HR 200 MB Potentially, reduced lateral spacing within all North Atlantic MNPS airspace, FL350-FL400. USA via . Each day, over 2000aircraft travel across the Atlantic ocean bound for North America or Europe on the North Atlantic Organized Track System. These routes are not created daily like the NATS. Random route flights should normally be planned at flight level(s) appropriate to the direction of flight. The correct method is to file a flight plan with an Oceanic Entry Point (OEP), then the name of the NAT Track, e.g. This is done to accommodate traditional airline schedules, with departures from North America to Europe scheduled for departure in the evening thereby allowing passengers to arrive at their destination in the morning. Many plans are indeed sub-optimal, and crossing the NAT certainly has the potential to result in a track a half-degree north or south of the one requested or a level below the optimum but is the inefficiency really that high? No special authorization or LOA is required to operate in RLatSM. Constantly changing. Those numbers look far closer to what we might expect as total efficiency losses identified at the end of Part One, above. European SigWx| In other words, OFW ATC = MFT = MTT = MCT. A reduction in volume goes hand in hand with a reduction in complexity from an ATC perspective. In 2012 approximately 460,000 flights crossed the North Atlantic. W north atlantic turbulence westbound tracks. The answer is North Atlantic Tracks. Europe loop| The altitude difference would have made for a greater fuel burn than a slightly longer distance, so the crew elected to take the more northerly track (30 nautical miles further north laterally, but in terms of distance flown adding about 20 nautical miles). Similarly, eastward tracks are named incrementally from the end of the alphabet (Z,Y,X), with the southernmost tracks named first. The air traffic controllers in Gander, Newfoundland will assign us our actual track as we approachtheir airspace. These routes are dominated by aircraft flying between the altitudes of 29,000 and 41,000 feet inclusive. Airlines that fly the North Atlantic regularly send a preferred route message (PRM) to Gander and Shanwick, showing what the route preferences are. Aircraft cannot change assigned course or altitude without permission. Fig.24.2(Upper ) Trajectories(gray . WEST LVLS 310 320 330 340 350 360 370 380 390. Nothing wrong in that. It covers a 24 hour period over the North Atlantic. R This, I think, is important to consider. North Atlantic Oceanic FIRs, *********SEE NOTAM A1715/15 NOTAMCZQX B) 1503060900 C) 1504302359 ********. I photograph airliners flying overhead in my town of Bathurst, New Brunswick, Canada, with a high powered zoom camera. These reports enable the Oceanic Controllers to maintain separation between aircraft. Pilots on North Atlantic Tracks are required to inform air traffic control of any deviations in altitude or speed caused by avoiding weather, such as thunderstorms or turbulence. [citation needed], The FAA, Nav Canada, NATS and the JAA publish a NOTAM daily with the routes and flight levels to be used in each direction of travel, available online. 48 HR| Starting from . Click on the Corresponding Letter to See the Current SIGMET Iceland Radar | | Europe 24H With the choice of track made, the operator will then file the Flight Plan with their requested route, several hours in advance of the flights departure from JFK. To see how it allworks, well ridealong with AeroSavvy Airlines flight 105 from New York, JFKto London, Heathrow. These heavily travelled routes are used by aircraft travelling . Always a great read while slurping the first cup of joe for the day with fellow airport bums.Keep it up and thanks. Minimum Fuel is good. I have always been curious about the routing over the north Atlantic. 0600z | 1130 1900 Eastbound (avoiding OTS). Despite advances in navigation technology, such as GPS and LNAV, errors can and do occur. The first implementation of an organised track system across the North Atlantic was for commercial shipping, dating back to 1898 when the North Atlantic Track Agreement was signed. 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 About. If you track aircraft using, for example, Flight Radar24, you will know that there are radar blackspots. NAT Basics: An Unofficial Checklist For Pilots. The three North Atlantic Routes used for Concorde were as below. [Our system recognizes the SelCal tones and rings the chime in the cockpit. Control the animation using the slide bar found beneath the weather map. Q. TUDEP 52/50 54/40 56/30 57/20 SUNOT KESIX. OTS tracks separated using RLatSM will be established by publishing one track defined by 1/2 degree waypoints (e.g. Random routeclearances are issued the same way as trackclearances. Why those times? hours westbound 1100-1600 and 0400-0900 eastbound, along similar tracks and at similar flight levels and speeds (Fig. There are several standard, published airways connecting South America and Europe. 1200z | They ensure that aircraft are separated over the ocean, where there is little radar coverage. 08: Actual Flown Route. 0600Z Sig Wx| BW Because of the volume of NAT traffic, allowing aircraft to choose their own co-ordinates would make the ATC task far more complex. Now consider the Oceanic environment. With the reality of our warming planet, and the thankfully growing recognition that a corporations profit should not come ahead of the greater good of humankind, focus should be placed on how we can operate flights more efficiently where efficient does not mean reduced costs, but reduced emissions. A few minutes before reaching LIMRI and XETBO, our oceanic exit points, AeroSavvy 105 will receive a CPDLC message like the one below. AeroSavvy 105, Gander, good morning, go ahead. The tracks are updated daily and their position may alternate on the basis of a variety of variable factors, but predominantly due to weather systems. To accommodate the twice-daily stampede, air traffic planners in Gander, Newfoundland and Prestwick, Scotland create weather optimized routesacross the Atlantic, called the North Atlantic Organized Track system (NATs). Loop 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. J With the standard NAT flight path, planes are required to fly 10 minutes apart horizontally (before and after) and 60 nm or one degree of latitude laterally (left and right). Atlantic Significant Weather Charts IR+Vis| UK NATS and Nav Canada create up to 12 tracks for westbound and eastbound traffic, designed . Application of Aviation Turbulence Information to Air-Trafc Management (ATM) Jung-Hoon Kim, William N. Chan, and Banavar Sridhar . We can see the traffic now, but we cant be sure that we can move it around in the same way as a real radar environment, because we dont have VHF. FL450 After saying hello to Gander Radio, well need to monitor their HF frequency in case the operator needs to talk to us. new 30-mile separation. For backup communications, we useold-school HF (high frequency) radios. They were valid for all flights reaching 30 W from 11:00 to 19:00(UTC). Given that the research paper mentioned above identifies maxium fuel savings eastbound of 16.4%, this is a good example to choose. Im preparing for my interview with Atlas Air and this article sums it up nicely for me. 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). I spent 30 years controlling the Notth Atlantic and running visits for aircrew and operational personnel. 340 350 360 370 380 390 400. I know that routes go close to north africa and fron there the transatlantic route starts, but how do they know what route? In the cold light of operational reality, however, all is not as the public coverage seems. - Jetban 2300-0700 LCL time; Weekends 2330-0800 LCL. SIGWX | within NAT minimum navigation performance specifications (MNPS) N Traffic levels are lower at present about 40% of normal. Huge fuel savings could follow) and the Independent (Surfing the wind could allow aircraft to cut carbon emissions and reduce flight times). Eastbound track labels are at the end of the alphabet (W, X, Y, Z). On a typical flight, we wont need to talk to anyone again until we approach 30 west longitude. The operators relay information between air traffic controllers and pilots. 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. From 1130z - 1900z all that traffic flies back to North America. What a nice article !!! A position report provides an aircrafts location, speed, and altitude so the controller can build a 3D picture of all the traffic. RWY 01 /19 5141'x148' SFC:ASP Elev:29 PCN:035FAXT, RWY 13 /31 4035'x148' SFC:ASP Elev:38 PCN:025FAXT, RWY 06 /24 3150'x98' SFC:ASP Elev:39 PCN:015FAXT. Planned the bird for a random route above the track for vantage of higher flight level, (but exactly over the track for taking advantage of the winds). SIGWX | CPDLC (Controller-Pilot Data Link Communications) and ADS-C (Automated Dependent Surveillance-Contract) are required FL350 to FL390 (inclusive) throughout the entire ICAO NAT region. The chart below can be used to help decode the information. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Want to talk to us? 07: Flight Plan Route (FPL). Traveling from America to Europe: Eastbound track. [6], Concorde did not travel on the North Atlantic Tracks as it flew between 45,000 and 60,000ft (14,000 and 18,000m), a much higher altitude than subsonic airliners. 09 z Much of the air traffic over the North Atlantic (NAT) is part of two major alternating flows: a westbound flow departing Europe in the morning, and an eastbound flow departing North America in the evening. FL380 0300 0700 Westbound (ODL, on and to the North of the North datum line). For the first time in decades and possibly since its inception (we're trying to work out exactly when, but at least the 1960s) there were no westbound tracks across the North Atlantic. This site is informational in nature and is designed to assist pilots and aircrews for flight planning and familiarization.It may be used in conjunction with other pre-flight information sources needed to satisfy all the requirements of 14 CFR 91.103 and is not to be considered as a sole source of information to meet . We need dramatic change. This allows more traffic to operate on the most efficient routes, reducing fuel cost. After World War II, increasing commercial airline traffic across the North Atlantic led to difficulties for ATC in separating aircraft effectively, and so in 1961 the first occasional use of NAT Tracks was made. . You are appreciated!! Three: A review of the research report from Reading University. (Inside Science) -- On March 9, 2021, not a single airliner flew westbound across the North Atlantic. In the winter months in particular, the eastbound jet stream can be nasty. Prior to departure, airline flight dispatchers/flight operations officers will determine the best track based on destination, aircraft weight, aircraft type, prevailing winds and air traffic control route charges. Q ), with the northernmost tracks named first. Take a look at the screenshot I took of the North Atlantic at about 00:10 hours on Monday, August 26th, 2019, UTC. Have you ever wondered how pilots navigate and communicate during the journey? Due to the volume of NAT traffic, allowing aircraft to choose their own co-ordinates would be impossible to manage. .. A while ago, Ive done a mistake during planning a flight. | That apart, Id like to add a point about planning too !!! or waivers will be permitted, due [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. Similar to CPDLC Tracks, certain equipment codes must be included in items 10a, 10b and 18. As a result, in the past 10 days the NAT Tracks have featured on CNN (Airlines can now pick their own routes across the Atlantic. This page was last edited on 1 November 2022, at 21:11. | Europe 24H HF has been usedin aviation since the 1920s. K Atlantic Satellites AeroSavvy 105 is off the ground and heading northeast toward Nova Scotia. Conflict solved. ; Due to continuing safety concerns associated with the non-adherence to, or incorrect execution of, Oceanic Clearances and tactical reroutes, the FAA evaluated its current method of issuing an Oceanic Clearance by . Customs hours 0800 LCL- midnight. 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. knock on schedule effects, missing curfews etc.). Listening to HF static for hours is miserable. 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. Controllers collate the airlines preferred routings and create the Organized Track System (OTS), a set of routes using GPS positions. Instead, it flew at a much higher altitude than subsonic airliners, namely between 45,000 ft and 60,000 ft. NA Sat| Potentially, reduced lateral spacing within all North Atlantic MNPS airspace, FL350-FL400. Ideal time to try it out. So Track V has the Foxxe-Loach exit pair over Canada, then the numbers indicate the latitude and longitude, meaning 57/50 is 57N and 50W, and so on. The only options for non CPDLC/ADS-C aircraft are Flight Levels below/above or very far North or South. Takeoffs not allowed during jetban hours. For our flight to London, AeroSavvy 105s dispatcher requests track Uniform in our flight plan. In this example flight, there are moderate-severe turbulence warning patches at several points on the ATC OFW/MCT route above, so the dispatcher elects to move it a little further north still gaining from the eastbound jetstream, but outside the core jetstream which has the highest turbulence. For operations outside of OTS times and/or the OTS structure, flight plan levels in accordance with the above flight allocation scheme. Westward tracks are named incrementally from the beginning of the alphabet (A,B,C. North Atlantic Tracks for the eastbound crossing on the evening of May 4, 2006. . 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). 2019 - ASEPS (Advanced surveillance enhances procedural separation) introduced following introduction of Space Based ADS-B. London's Heathrow Airport had the greatest number of transatlantic departures (136) and arrivals (127). 200 MB, Atlantic Significant Weather Charts Facilities with a call sign suffix of Radio (like Gander Radio) are typically HF radio services staffed by professional operators. North Atlantic Tracks. 24 HR| Eastbound| These reports can be made to dispatchers via a satellite communications link (CPDLC) or via high frequency (HF) radios. The difference? The weather variations at these altitudes were so minor that Concorde followed the same track each day.
