Canada Radar| 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. Same logic as NATs? At 30 West, well switch over to Shanwick Oceanic Control, which raises the question: Where the heck is Shanwick? In Short: Strategic Lateral Offset Procedures (SLOP) costs nothing and increases flight safety. Every day, from 0100z - 0800z (8 pm - 3 am EST) hundreds of airliners fly eastbound from North America to Europe. Routes are aligned along NATs in such a way as to minimize any headwinds and maximize the impact of tailwinds on the aircraft. Global warming is a danger to our entire existence. NATS always puts out great stuff! Traffic levels are lower at present about 40% of normal. We wont find out which track we are assigned until we are airborne and approaching the track system. Eastbound track labels are at the end of the alphabet (W, X, Y, Z). 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. Europe IR| The city names were combined to create Shanwick. N453A N441A. So, controllers can see the aircraft in much the same way as a domestic radar controller. Minimum Cost Track, by far. That apart, Id like to add a point about planning too !!! from North) to the counterclockwisefrom East as shown in Fig. Views: 13,129. In the old days, pilots reported their position by HF radio every 10 longitude. The North-Atlantic Weather Map below shows the weather forecast for the next 12 days. 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. Whole Atlantic / 1130 2000 Eastbound (avoiding OTS). W 03 z Traveling from Europe to America: Westbound track. Well look at an eastbound flight from New York Kennedy (JFK/KJFK) to London Heathrow (LHR/EGLL). This allows more traffic to operate on the most efficient routes, reducing fuel cost. | February 5, 2015, defines vertical and lateral dimensions of airspace PERFORMANCE ASSESSMENT OF OPERATIONS IN THE NORTH ATLANTIC ORGANIZED TRACK SYSTEM AND CHICAGO O'HARE INTERNATIONAL AIRPORT NOISE STUDY Nikolaos K. Tsikas ABSTRACT This thesis consists of two topics. - Open 24 hours. The first RLAT tracks were published in December 2015. Special thank you to Christian Kovanen 1379372 for the boundaries and fixes. We can always request a change while enroute, but we may not get it. 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. Get a forecast by email. However, the choice is left up to the pilot. Potentially, reduced lateral spacing within all North Atlantic MNPS airspace, FL350-FL400. The correct method is to file a flight plan with an Oceanic Entry Point (OEP), then the name of the NAT Track, e.g. Since they cant see the aircraft, controllers rely on pilots to report their position at regular intervals. 36 HR| North Atlantic Tracks| The codes are two pairs of letters(like CG-MS). Oceanic boundary points for the NAT Tracks are along the FIR boundary of Gander on the west side, and Shanwick on the east side. WEST LVLS 310 320 330 340 350 360 370 380 390. 18 z The routes dont change daily like over the North Atlantic. Now its digital (and much easier). T 6 HR | The report does identify, when looking at actual flights, that efficiency savings of 2.5% for eastbound flights and 1.7% for those flying west would be obtained by flying the optimum wind route (OFW). North Atlantic Tracks for the eastbound crossing on the evening of May 4, 2006. |, 500mb Analysis | 0100 0800 Westbound (avoiding OTS). Almost all of the time, the requested track is granted, albeit with potentially a lower level (or higher) than requested. Europe Surface Delta 63: Roger, right turn heading 280. 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. . Latest Analysis | If youre crossing the Atlantic (as a passenger), celebrate the halfway point with a mug of suds. Eastbound OTS (subject to. 02: OFW: Optimised For Wind route. Increased aircraft density can be achieved by allowing closer vertical spacing of aircraft through participation in the RVSM program. A reduction in volume goes hand in hand with a reduction in complexity from an ATC perspective. These routes are not created daily like the NATS. 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. RLAT reduces the standard distance between NAT tracks from 60 to 30 nautical miles (69 to 35mi; 111 to 56km), or from one whole degree of latitude to a half degree. Its been a busy few hours, but AeroSavvy 105 is now headed out to sea. If you've ever watched a placid thread of rising . Click on the Corresponding Letter to See the Current SIGMET While typically not dangerous, two aircraft can violate separation requirements. Surface Winds Model The purple track above at Step 6 (closest NAT Track) becomes the yellow track in this step, to which the domestic ATC routings are added. Atlantic - 00h ; Atlantic - 06h ; Atlantic - 12h ; Atlantic - 18h ; Atlantic - Forecast with Eastbound NAT track overlay ; Atlantic - Forecast with Westbound NAT track overlay ; Atlantic - High Level Forecast ; Atlantic - Surface Wx Analysis ; Atlantic (Eur/Afr/Ame) - Maps Atlantic / North Pole - Maps Central Pacific - 00h ; Central Pacific - 06h matching the Operator Preferred Route to the closest NAT Track of those published for the day of flight. Obs/Tafs| You can also view the westbound tracks . AeroSavvy 105 is off the ground and heading northeast toward Nova Scotia. Entrance and movement along these tracks are controlled by special Oceanic Control Centres. In 1965, the publication of NAT Tracks became a daily feature, allowing controllers to force traffic onto fixed track structures in order to effectively separate the aircraft by time, altitude, and latitude. FL340 (Inside Science) -- On March 9, 2021, not a single airliner flew westbound across the North Atlantic. Get a forecast by email. Controller: Delta 63, roger, turn right 10 degrees due traffic.

M 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. Euro Control Validator |, Canada Radar| Due to the volume of NAT traffic, allowing aircraft to choose their own co-ordinates would be impossible to manage. 21 z | This is an experiment being led by NATS and Nav Canada (or Shanwick and Gander, if you prefer), and on the face of it, it appears straightforward. D Turbulence and thundestorm historical data of the North Atlantic Ocean. Latest Analysis | There was no fanfare or fireworks, but last Tuesday was a significant day in the history of transatlantic air travel. Now consider the Oceanic environment. | 12 HR| 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). K Similar to CPDLC Tracks, certain equipment codes must be included in items 10a, 10b and 18. 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. The MTT and MFT will go through Russia [where navigation fees are much higher]. Im preparing for my interview with Atlas Air and this article sums it up nicely for me. I am sure you can see the pattern: the NATs! 200 MB, Atlantic Significant Weather Charts north atlantic turbulence westbound tracks. Obs/Tafs| Aircraft cannot change assigned course or altitude without permission. . 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. The definition of turbulence is fairly straightforward: chaotic and capricious eddies of air, disturbed from a calmer state by various forces. They ensure that aircraft are separated over the ocean, where there is little radar coverage. Westbound tracks are labeled A, B, C, D, etc. V FOXXE LOACH 57/50 58/40 58/30 57/20 SUNOT KESIX. 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 | Europe 24H The NAT Track Message. In January 2017, the ICAO SPG (Authority for the NAT region) published updated guidance indicating that SLOP is now a requirement on the North Atlantic, rather than a recommendation. I spent 30 years controlling the Notth Atlantic and running visits for aircrew and operational personnel. Before we can fly across the Atlantic, we need to select a track (or route). And therefore, removing the NAT Organized Track Structure for high volumes of traffic is a big challenge. 2230 0059 Westbound (avoiding OTS). the 25 nautical mile (NM) reduced lateral separation minimum (RLatSM). Airline dispatchers and pilots use the published tracks to plan the days flights. In the case of HF reports, each aircraft operates using SELCAL (selective calling). 1/4. But this overlooks a key point: its not a surveillance problem, its a comms problem. 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. 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). This article is intended to provide an overview of the busiest segment of that airspace, the Organised Track System (OTS). Flights equipped with and prepared to operate FANS 1/A (or equivalent) CPDLC and ADS-C Storms are also possible in the red areas which also indicate the possibility of turbulence. This allows the ATC agency to know what the route preferences are of the bulk of the North Atlantic traffic. Check out this amazing visualization produced by NATS (National Air Traffic Services), the main air traffic control provider in the UK. 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. Select from the other forecast maps (on the right) to view the temperature, cloud cover, wind and precipitation for this country on a large scale with animation. ), with the northernmost tracks named first. P It can take anywhere from a few minutes to an hour to receive an oceanic clearance from Gander. C These headline figures are the ones taken by the media in the last few weeks resulting in articles suggesting that the average New York-London flight could arrive 21 minutes earlier [Independent >]. due to turbulence etc., ATC must be notified as soon . Unless suitable eastbound Tracks exist, during the eastbound OTS times, eastbound traffic originating in New York . A few years ago, all the clearances were issued by voice over the radio. Well written article for the aviation enthusiast, aviation professional and general public alike. Left is for losers - don't SLOP left of track. Surface Precip Model U Expected weather and turbulence on transatlantic flights headed west, usually flying north of the eastbound tracks. In the three following months, 31,700 flights could fly at their optimum speeds, saving up to 400650kg (8801,430lb) of fuel per crossing. Sig WX FL100-240| The average saving for all ATM tracks is 232 km. | 05: Published NAT Tracks. They ensure that aircraft are separated over the ocean, where there is little radar coverage. Each day up to twelve tracks are created west and eastbound, designed to take advantage of the day's Jet Stream and give the airlines an efficient route across the . Id like to thankthree fellow professional aviators (and Twitter celebs) for helping meimprove this article. 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 . 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. The controllers must take all the requests and make sure aircraft are appropriately spaced along the tracks. 1200z | 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. Euro Control Validator | Therefore, most operators choose to file a flight plan on a NAT Track. 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. Thanks for the nice comments. H 29 MAY 09:01 2014 UNTIL Westward tracks are named incrementally from the beginning of the alphabet (A,B,C. Source: turbli's historical database, built from the daily forecasts provided by NOAA and the UK Met Office. G Thank you for reading. Content. arranged for arrivals/departures at any time during the night. The OFW route as adjusted for oceanic ATC flight planning limitations which are: 1. 24.1. Thank you for sharing. We need to open our minds, stop being quite so defensive about aviation, collaborate with science and research, and above all recognise the impact that aircraft are having on the environment. 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. North Atlantic Tracks are published by Shanwick Centre (EGGX) and Gander Centre (CZQX), in consultation with other adjacent air traffic control agencies and airlines. 1800z On the maps that follow, you will see the there are eight steps, starting with the great circle track, and working through what happens in practice until we reach the actual route flown. Takeoffs not allowed during jetban hours. Latest Analysis| ], Gander, AeroSavvy 105, SelCal OK, over. These heavily traveled routes are used by aircraft traveling between . These routes are dominated by aircraft flying between the altitudes of 29,000 and 41,000 feet inclusive. Europe loop| You must use fixed 1/2 degree latitude points at every 10 degrees of longitude from Oceanic Entry Point to Oceanic Exit Point. The shortest distance between JFK and LHR. This results in much more efficiency by reducing fuel burn and flight time. In other words, OFW ATC = MFT = MTT = MCT. Figure 1: The annual mean North Atlantic zonal (west-east) winds at 250 hPa (around 34,000 feet) from 1979-2017, according to the NCEP/NCAR reanalysis dataset. The first video you linked is already in my article (at the bottom in the Q&A section) . Half tracks are designed to increase aircraft density by allowing closer horizontal and lateral spacing of aircraft. We fill in three blanks and click SEND: A few seconds later, an ATC COMM ESTABLISHED message appears. Europe IR| Q HF has been usedin aviation since the 1920s. Equivalent to the OFW/Optimized for Wind Route. 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. FL390 I still enjoy sitting by the window and seeing the expanse of Nova Scotia and Newfoundland unfold beneath my flight. 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. Thats the basis of RCP240. 1200Z Sig Wx| EAST NIL. Canada|, Satellites- Every day, from 0100z - 0800z (8 pm - 3 am EST) hundreds of airliners fly eastbound from North America to Europe. In simple terms, the number of aircraft that can fly closer to the optimum route for a city pair has dramatically increased. A few minutes before reaching LIMRI and XETBO, our oceanic exit points, AeroSavvy 105 will receive a CPDLC message like the one below. Only sensible if there is no wind, which never happens. Atlantic Ocean. 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. K Eastbound| From 1130z - 1900z all that traffic flies back to North America. This, I think, is important to consider. the westbound North Atlantic Organised Track Structure. | Europe 24H (Image courtesy of eWAS Pilot) . Hi. 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. R 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. : Did you know that Concorde did not travel on the North Atlantic Tracks? Sig WX FL100-240| Whole Atlantic / 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. F Today, we have been cleared across the Atlantic on Track Uniform as we requested. To make such efficiencies possible, the routes are created twice daily to take account of the shifting of the winds aloft and the principal traffic flow, eastward in North America evening and westward twelve hours later. This is often also where the core efficient NAT Track Xray or Zulu lies these days. Aircraft without approved CPDLC Very ocasionally, a track one north or one south is given by ATC. On a typical flight, we wont need to talk to anyone again until we approach 30 west longitude. Satellites- The NAT track message details all of the agreed-upon North Atlantic routings for the flow and messages are typically published twice a day, at 2200z and 1400z. time and restrict access to optimum tracks. 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? 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. Each airline requests a track that will give their flight the best fuel efficiency. | In fact, there are fundamental flaws in the assumptions made to reach the headline proclamations of 16.4% and 230km (125 nautical mile) savings on route distance. You need to make sure your aircraft isnt already listed as having failed to meet these criteria, by checking here. Flights which are planned to remain entirely clear of the OTS or which join or leave an OTS outer track are considered to be on a random route. Email is always easiest: a good one to use is messages@ops.group. 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. . 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. There are normally 8-10 NAT Tracks eastbound. If you track aircraft using, for example, Flight Radar24, you will know that there are radar blackspots. There are four maps available at any one time, each valid for about six hours, according to the UTC/GMT time. (Not to be confused with the AeroSavvy Barista). NIL. 25 NM lateral separation will be applied between flight level 350-390 (inclusive). [citation needed], A random route must have a waypoint every 10 degrees of longitude. NA Radar| Westbound (OTS). Welcome to NOTAM Search. Track B and D are also subject to the same equipment conditions required for Track C if at FL350 to FL390. The east Atlantic region that AeroSavvy 105 will overfly is called the Shanwick Oceanic Control Area. 07: Flight Plan Route (FPL). Published in January 2021, a paper from Reading University titled Reducing transatlantic flight emissions by fuel-optimised routing suggested that current flight tracks [on the North Atlantic] have air distances that are typically several hundred kilometres longer than the fuel-optimised routes, that by using the optimal wind route eastbound flights would save on average 232 km, and that an efficiency gain of up to 16.4% would be possible. Starting March 1, operators may file random route plans for North Atlantic tracks at or below FL330. Which is the most commonly used? J Therefore, the winds shown are those at FL390. I just stumbled on this fascinating article. E RWY 18/36 10000'x197' SFC:CON Elev:283, FANS 1/A (or equivalent) CPDLC and ADS-C capability. A note from the AeroSavvy Barrister Satellite: view. Eastern Satellite| V Cargo flights often fly across the Atlantic at times when the tracks are flowing in the opposite direction, so they fly random routes. Wow,,,what a nice explination about NATsAs a airlines pilot, it is a really well understandable & easy one Thanks. One big consideration: Turbulence. 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. I would like to know what routes are followed from europe to south america and viceversa. In the example above, Track C is the RLatSM track. Turbulence areas are indicated with dashed red lines. Listening to Gander and New York OAC, on HF, I wish I could get waypoints names and coordinates over the Atlantic, thank you. D They are aligned in such a way as to minimize any head winds and maximize tail winds impact on the aircraft. 6 HR Y . North Atlantic Skies (2014) from NATS on Vimeo. At the end of the article theres a link for the FAAs North Atlantic Track NOTAM. USA via . Their Santa tracking videos are the best. Daily publication of tracks for aircraft use began in 1965. Oceanic ATC, even with this additional surveillance, remains more of a procedural environment and separation standards cannot yet drop. The chart below can be used to help decode the information. I really appreciate your nice comments! R Ken, you might help clarify a little mystery for me. 09 z And Delta turns. Icing & Turb [Our system is working and well monitor the frequency using SelCal], Gander. When we are issued an oceanic clearance, the clearance is for a specific speed and altitude. D. MCT: Minimum Cost Track. In the winter months in particular, the eastbound jet stream can be nasty. [1] In 1966, the two agencies at Shannon and Prestwick merged to become Shanwick, with responsibility out to 30W longitude; according to the official document "From 1st April, 1966, such a communications service between such aircraft and the said air traffic control centres as has before that date been provided by the radio stations at Ballygirreen in Ireland and Birdlip in the United Kingdom will be provided between such aircraft and the said air traffic control centre at Prestwick or such other air traffic control centre in the United Kingdom as may from time to time be nominated". Icing The tones triggera chime in the cockpit to alert the crew they are needed on the frequency. Controllers collate the airlines preferred routings and create the Organized Track System (OTS), a set of routes using GPS positions. | FL340 Aviation contributes around 2% of global CO2 emissions. RWY 08 /26 11046'x209' SFC:ASP Elev:153 PCN:076FBXU, RWY 16 /34 9580'x200' SFC:ASP Elev:149 PCN:061RBXT, RWY 06 /24 10495'x148' SFC:ASP Elev:46 PCN:075RCWU, RWY 10 /28 8652'x148' SFC:CON Elev:202 PCN:070RBWT, RWY 16 /34 6798'x200' SFC:ASP Elev:202 PCN:075RDWT, RWY 11 /29 10056'x197' SFC:ASP Elev:171 PCN:080FCWT, RWY 02 /20 10019'x197' SFC:ASP Elev:163 PCN:068FBWT. Only thing is Ive planned it with a step level due to weight/fuel restrictions, with the step happening AFTER the track entry point !!!! In this case, it is highlighted in purple, and is a relatively close match. The same dispatcher told me: In the last week, weve not flown the NAT Tracks because of multiple patches of severe turbulence, both forecast and reported by other airlines. European SigWx| Our CPDLC and ADS will automatically log off Ganders system and logon to Shanwick like magic! NATs are like a multi-lane, one-way highway in the sky.

G click for more flight level/times, North Atlantic Turbulence Currently airliners emit 2.7% of the carbon dioxide in the atmosphere. north atlantic tracks map. C. MTT: Minimum Time Track. Also depicted is the great circle route whose location is combined with the forecast winds to establish the North Atlantic Track System (NATS) tracks on a twice-daily basis (Williams and Joshi, 2013; FAA, 2019a). The controller then bids us farewell: radar services terminated, have a nice day!, Gander Center (VHF) vs. Gander Radio (HF). Turbulence forecast for North Atlantic Eastbound tracks valid on 2023 01 16 at 00 UTC for FL280-430. applicability and within NAT organized track system (OTS) ranging from It reduces the chance of collision for non-normal events such as operational altitude deviation errors and turbulence induced altitude deviations. The radio operators are based just to the north of Shannon but the ATC service is provided by the Scottish Centre at Prestwick. General. Conflict solved. . 2230 0059 Eastbound (subject to westbounds). About. However, authorizations are required for the minimum surveillance and navigation requirements(RNP4, FANS 1/A) necessary to operate in RLatSM. Westbound| Watch carefully to see random route flights flying opposite to thedirection of the tracks (full screen and audio highly recommended! Our team loves to help! Loop The only options for non CPDLC/ADS-C aircraft are Flight Levels below/above or very far North or South. 1200Z Sig Wx| Phase 22015 . The trackschange each day to provide the most efficient routes for the airlines. The Oceanic Controllers then calculate the required separation distances between aircraft and issue clearances to the pilots. Air Ground Communications System (AGCS) is required by Gander Oceanic to receive your oceanic clearance via datalink. 300 MB 0000Z Sig Wx| Info. Thus, crew members need not devote their attention to continuous radio listening. | And even then, thats not the track the operator might want to fly. May be Flight Planned as eastbound by non-RVSM aircraft. Two: The ATC perspective; why No NAT Tracks is not as easy as it might sound. The Molson/Guinness Line leaves me wondering if many aircrew still think Shanwick Control is based in Ireland. RWY 09 /27 10000'x200' SFC:ASP Elev:84 PCN:067FAWT, RWY 02 /20 3900'x150' SFC:PEM Elev:36 PCN:025RAWT. Entrance and movement along these tracks is controlled by special oceanic control centres to maintain separation between aircraft. [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.
