On the Era 57 Gen 2 that licence is installed at the factory; on a first-generation Era you buy it and load it yourself. This article covers which instruments can run Atmo, how to buy and install the licence, and how to check that Atmo is working. For what Atmo actually measures, see [Atmo 3D wind: what it measures and how it works](\u002Fkb\u002Farticle\u002Fatmo-3d-wind-what-it-is).\n\n## Which instruments can run Atmo\n\n| Instrument | Atmo |\n|---|---|\n| Era 57 Gen 2 | Built in — the licence is installed at the factory, nothing to do |\n| Era 80 and Era 57 (first generation) | With the [Atmo 3D wind licence](\u002Fshop\u002Fatmo-3d-license) |\n| Era essential 80 and 57 (first generation) | With the same licence |\n| Era essential 57 Gen 2 | With the same licence |\n\nIf the licence on an Era 57 Gen 2 is ever erased — a service code can do that — contact us and we will send the file again.\n\nEvery Era carries the motion sensors Atmo needs, so no hardware is added and nothing in the panel changes. What the instrument does need is what it needs anyway:\n\n- its own GPS receiver, with the antenna connected and a clear view of the sky — an Era that takes its position from a FLARM unit instead cannot run Atmo\n- pitot and static connected and leak-free — Atmo works from the instrument's own pressure sensors\n- the instrument fixed firmly in the panel\n- current firmware\n\n**If your glider has an LX AHRS module.** With Atmo running, the Era's AHRS page shows Atmo's own attitude estimate instead of the module's; an iLevil or gMicro connected to the Era still takes precedence. If you use the AHRS page, compare the two on the ground and in your first flights after installing the licence.\n\n## Buying the licence\n\nThe licence is made for one instrument: the file is computed from that Era's serial number, works on that unit only and cannot be moved to another one.\n\n1. **Find the serial number.** It is on the label on the back of the instrument, on the start-up screen, and under `Setup › Service › Device Info`. The shop asks for six digits — if your Era shows a shorter number, add leading zeros (`34123` becomes `034123`).\n2. **Order the [Atmo 3D wind licence](\u002Fshop\u002Fatmo-3d-license)** and enter the serial number at checkout. You can also leave the field empty and enter it later: the e-mail you receive after payment carries a link for that.\n3. **Download the file.** As soon as the serial number is known, the licence file is generated and ready to download, and you can download it again from your account at any time. Its name is `Fusion.lic`.\n\nYour dealer can order the licence for you in the same way.\n\n## Installing it\n\n1. **Update the Era to the current firmware** first. The update file is in the [download centre](\u002Fdownloads) and the steps are in the Era user manual (`Setup › Service › Software update`). Leave the instrument switched on until the update has finished — including the CAN devices it updates afterwards.\n2. **Copy `Fusion.lic` to the root of the micro SD card** — not into a folder. Keep the file name exactly as it is. If your computer saved a second download as `Fusion (1).lic`, rename it back to `Fusion.lic`, because the Era looks for that exact name.\n3. **Insert the card** into the Era and go to `Setup › Service › Load license`.\n4. **Select the `Fusion` licence file** and confirm. The Era copies it into its internal memory.\n5. **Switch the Era off and on again** (`Setup › Shutdown`, or cut the power). The GPS receiver is set up for Atmo only when the instrument starts, so Atmo comes to life on the next power-up, not the moment the file is loaded.\n\n> **Loading the licence needs no password.** Do not type anything under `Setup › Service › Password` unless LX support gives you a code: codes there delete flights and settings, erase licences or change the instrument's identity.\n\n## Give Atmo a good level reference\n\nAtmo takes its level reference each time the Era is switched on, from the way the glider stands while the GPS is still searching. A glider resting on its wheel and tail is rarely in its flight attitude, and the difference shows up as a steady offset of the smart vario in straight flight.\n\nFor the best reference — and certainly for your first flights with Atmo — switch the Era on with the glider in flight attitude: wings level and the tail raised on a trestle to the attitude the glider manual gives for levelling. Keep it still until the GPS has a fix, then move it as you like. [Calibration, accuracy and troubleshooting](\u002Fkb\u002Farticle\u002Fatmo-3d-calibration-and-troubleshooting) explains how much this matters and what else to expect.\n\n## Checking that it works\n\nOn the ground Atmo shows nothing, and that is correct: it has no airflow to work with. The proof is in the air.\n\n- **Before takeoff** the Wind page reads `No data`. It is one of the pages you turn through with the `PAGES` knob, next to the G-force page; if you do not see it, switch it on under `Setup › Pages`.\n- **A few seconds after takeoff** the Wind page fills in: the current wind first (the bottom value, with a blue arrow), the average a little later (the grey value at the top). A second, cyan needle appears on the vario scale beside the familiar one.\n- **If you use a flight app** connected over NMEA with the `LXWPx` output enabled, the `$LXBC,FUSION` sentence carries wind and vario values about once a second once Atmo is running.\n\nIf the Wind page stays empty in flight, work through the [troubleshooting table](\u002Fkb\u002Farticle\u002Fatmo-3d-calibration-and-troubleshooting) — the most common causes are a licence loaded without the restart that follows, and a file that was renamed on the way to the card.\n\n## Moving the instrument\n\nThe licence belongs to the instrument, not to the glider: if the Era moves to another glider, Atmo moves with it.\n\n## Where to go next\n\n- [Flying with Atmo 3D: the Wind page, the smart vario and the sound](\u002Fkb\u002Farticle\u002Fatmo-3d-flying-with-it)\n- [Atmo 3D: calibration, accuracy and troubleshooting](\u002Fkb\u002Farticle\u002Fatmo-3d-calibration-and-troubleshooting)\n- [Era: setup, wiring and first flight](\u002Fkb\u002Farticle\u002Fera-setup-and-first-flight)\n",null,{"categories":18,"articles":51,"search":77},[19,22,28,34,40,45],{"id":11,"slug":12,"name":13,"description":16,"sortOrder":20,"articleCount":21},15,5,{"id":23,"slug":24,"name":25,"description":16,"sortOrder":26,"articleCount":27},"42232637-6088-4100-9314-0b4986098818","getting-started","Getting started",20,7,{"id":29,"slug":30,"name":31,"description":16,"sortOrder":32,"articleCount":33},"9d0897b6-42d0-4643-8ceb-e8a02ce4a854","navia","NAVIA",25,11,{"id":35,"slug":36,"name":37,"description":16,"sortOrder":38,"articleCount":39},"92b87517-c814-4237-b180-19df9cb80b16","connectivity","Connectivity",30,3,{"id":41,"slug":42,"name":43,"description":16,"sortOrder":38,"articleCount":44},"db776f9a-4f67-42bf-94bc-171c93f10cea","service-repairs","Service & repairs",1,{"id":46,"slug":47,"name":48,"description":16,"sortOrder":49,"articleCount":50},"48e22b59-26c1-477f-b136-3d3728b6dc22","device-guides","Device guides",40,12,[52,58,59,65,71],{"id":53,"slug":54,"title":55,"summary":56,"visibility":9,"isPublished":10,"categoryId":11,"categorySlug":12,"categoryName":13,"updatedAt":57},"f365b994-4bad-49e1-bdcc-e8796f3e06a5","atmo-3d-wind-what-it-is","Atmo 3D wind: what it measures and how it works","The wind triangle in three dimensions, why Atmo needs no compass and no second antenna, what it learns in flight, what you see in the cockpit, and the honest limits of measuring wind from motion.","2026-10-23T11:54:53.787Z",{"id":5,"slug":6,"title":7,"summary":8,"visibility":9,"isPublished":10,"categoryId":11,"categorySlug":12,"categoryName":13,"updatedAt":14},{"id":60,"slug":61,"title":62,"summary":63,"visibility":9,"isPublished":10,"categoryId":11,"categorySlug":12,"categoryName":13,"updatedAt":64},"3f93eb93-aa78-4fd6-80ea-cf46ed9ebc60","atmo-3d-flying-with-it","Flying with Atmo 3D: the Wind page, the smart vario and the sound","Where the Wind page lives and how to read its two winds, what the smart vario shows in cruise, on thermal entry, in the climb and in manoeuvres, and how to put it on a needle, a navbox and the sound.","2026-10-23T11:54:53.812Z",{"id":66,"slug":67,"title":68,"summary":69,"visibility":9,"isPublished":10,"categoryId":11,"categorySlug":12,"categoryName":13,"updatedAt":70},"e06ea0f7-60ef-46a4-9b8d-73f82a97e8cb","atmo-3d-calibration-and-troubleshooting","Atmo 3D: calibration, accuracy and troubleshooting","What Atmo calibrates by itself, the level reference it takes from you, what accuracy to expect, and a symptom table for the questions pilots ask after their first flights.","2026-10-23T11:54:53.820Z",{"id":72,"slug":73,"title":74,"summary":75,"visibility":9,"isPublished":10,"categoryId":11,"categorySlug":12,"categoryName":13,"updatedAt":76},"ad551cb0-7738-4375-8f50-edae5b333775","atmo-3d-data-for-apps-and-second-seat","Atmo 3D data: second seat, NMEA and your own software","How Atmo shares its wind and smart vario with a second-seat instrument over CAN, and the $LXBC,FUSION and $LXBC,FAST sentences field by field for anyone building on them.","2026-10-23T11:54:53.828Z",false,{"AT":26,"BE":79,"BG":26,"CY":80,"CZ":79,"DE":80,"DK":32,"EE":81,"ES":79,"FI":82,"FR":26,"GR":82,"HR":32,"HU":83,"IE":84,"IT":81,"LT":79,"LU":85,"LV":79,"MT":86,"NL":79,"PL":84,"PT":84,"RO":80,"SE":32,"SI":81,"SK":26},21,19,22,24,27,23,17,18]
