  • DON'T FORGET TO READ THIS DISCLAIMER from the Worldwide Soaring Turnpoint Exchange! It applies to files downloaded via this website as well.!

  • BGA Waypoint lists 2021

    The list includes nearly 1400 Waypoints, amendments can be viewed by clicking here. It is important that you review the changes for 2021 because there are a number of changes within 100 Km of Booker.

    You can rename any of these files if you have your own preference, but the .CUP part should not be changed.


    If you just want the full BGA 2021 list then use the links in the first table to the Worldwide Turnpoint Exchange.

    Naming convention for "special" files. eg Wp21CPKtskcode
    Wp = Waypoint file
    21 = Year 2021
    CPK = Base airfield that the waypoints are designed to be used from (BGA = Full BGA List).
    tsk = file includes some local tasks for the base airfield.
    ol = file includes outlanding fields from the Paul Ruskin database as current on the date shown.
    code = Waypoint names in the file have had the waypoint code appended, this makes it easier to lookup waypoints on some devices.


    Waypoint lists with name prefixed by code - with "Code" added to the filename after bga.

    For some equipment it is helpful to have the waypoint name prefixed with the waypoint code. This makes it more obvious if the incorrect trigraph is selected.

    Example of TP selection screen.

    Example of TP selection on an LX computer - Which one is BO4?

    Example of TP selection screen.

    Example of TP selection on an LX computer with Trigraph prefixed names.

    files that have been prefixed in this way will have "Code" added in to the filename.


    Waypoint lists that include TASKS.

    Some waypoint files have a few handy pre-defined tasks that will appear on SeeYou or LX devices.

    You may find this useful to get started with if you have new equipment with no saved tasks.

    It is often quicker to modify a pre-defined task than to create a new one from scratch.

    You may need to set Start/Turnpoint/Finish zones for your requirement.

    PLEASE SAVE YOUR EXISTING TASKS BEFORE USE as these files often overwrite existing tasks.




    Landout airfields and field databases.

    Many navigation devices have pre-installed airfield databases, these should be kept up to date and can be used to identify airstrips that may be available for landout. In addition a number of people in the gliding community produce files of outlanding sites that can be merged with turnpoints or loaded as a separate file.


    Landout sites - Paul Ruskin Database.

    Paul Ruskin produces a regularly updated list of airfields suitable for landout with a 20M glider. Amendments to this list are made regularly and any observations should be fed directly in to Paul.

    You need to subscibe and register here in order to receive a link to the files, this will also ensure you receive regular updates.

    This database uses four character codes for landout sites. You should ensure that your device is displaying a minimum of four characters for waypoints to avoid ambiguity.


    Landout sites - database of UK airfields and farm strips.

    If you want to research a strip that you have seen whilst flying, the OurAirports website may help. This site has over 56,000 worldwide airfields on a zoomable map . Clicking on an airfield will provide an aerial photo of the strip and Latitude, Longitude details.

    It is possible to download all 56,000 airfields to Excel via the downloads page.


    Landout sites - additional local sites.

    Club members may also post additional lists of local landout sites to the club WhatsApp group. Files below provided by John O and Chris R.


    BEWARE! Pilots must make their own decision about how to use airstrips in these files. Private and Farm strip lengths and widths will vary and there may be crop, fences, wires, equipment and public footpaths on or close to the runway. BEWARE!

    Airspace files for 2021.

    If you own an Oudie then the easiest way to update your files is via the Naviter updater. You can add your own airspace files regardless of whether you have used the Updater. If you'd like more control of airspace file content then read on.


    Gliding equipment suppliers Navboys provide regular Airspace and Waypoint updates on their website. These files are generated from Asselect and usually include gliding and microlight airfields defined as Class G airspace (which they usually are).


    The files on the BGC Website are provided by Bob Smith. Also created in Asselect, they are split into different areas so may run faster on your device.

    ABO and LLE files provided for Booker Expedition Use. BOO File for XC Gliding in England. Use the Navboys or SeeYou supplied files if you have a modern device that easily loads large files.


    You can rename these files if preferred, the .CUB part should not be changed though.


    If you have a device that needs OpenAir format .txt files, these are available in the ZIP files.


    *Refer to the Airspace Notes spreadsheet or ( PDF version) for detailed information about these files.

    You can load any or all of these files to your device, but only one of these files should be active at any time.

    Gliding Waypoints - what are they.

    Waypoints are used to define the route to be taken during a cross country flight. They are used to identify the start and finish point, control points and turnpoints. The International Gliding Commision (IGC) specify the minimum information (Latitude, Longitude, etc) needed to define a Waypoint, but there is no international standard for naming these points, nor for how programs display them. Technically, any point on the Earth’s surface can be selected by a pilot as a turnpoint for use on a cross country flight. Obviously it would be pointless selecting waypoints in airspace that cannot be entered, or that are in hazardous locations.


    Gliding Waypoints - how are they created.

    In countries where gliding takes place a national organisation will usually coordinate or delegate creation of common waypoints. To find out more about how UK BGA Waypoints are defined you can read all about them on the BGA UK waypoint information website.


    A pilot may choose to use the same waypoints year after year, however, it is often convenient to use the same waypoint list as other pilots, the majority of UK pilots will use the Waypoint list published by the BGA. This BGA list is updated annually and published in the Spring. In order to ensure that pilots flying a common task go to the same point, or that a badge declaration is accurate, it is essential to use the correct update (or make the required amendments to your own files). Using an old version of waypoint data may also lead the unobservant user towards forbidden territory; for instance waypoints were removed in 2019 because of restricted airspace.


    How do I get a file for my device?

    It is possible to download files for most devices and most countries from the Worldwide Soaring Turnpoint Exchange. UK waypoints on this site are updated a short while after the official BGA list is updated; it is important to ensure you are viewing the latest data.


    LINKS DIRECTLY TO THE MOST POPULAR FILES CAN BE FOUND NEAR THE TOP OF THIS PAGE.


    How do I get waypoints on to my navigation device(s).

    Most devices can be updated by transferring a waypoint file. This is usually the least complicated method and is often done via USB or memory card with no other software required

    Some devices can be updated via PC/Mac software holding waypoint databases, this can end up being more complex because it is often necessary to understand the workings of the PC/Mac software before the waypoints can be loaded. For example, an Oudie can also be updated using a Wizard within SeeYou software.


    Activating the waypoints on my navigation device(s).

    With some older gliding loggers and GPS systems loading new waypoints would replace the old waypoints and they would immediately become the "active" ones in use. Most modern devices such as the Oudie and LX systems will save as many (differently named) waypoint files as you like, but after loading it is necessary to select the file that you wish to use. On these devices it is easy to go back and re-select the old file (assuming it had a different name to the new one) to revert to previously used waypoint lists.


    How do I manage waypoints on my PC/Mac.

    You do not need to manipulate turnpoint files unless you would like to add or remove your own points or add your own tasks. With some older equipment it may be necessary to reduce the number of turnpoints in a file due to limitations of the equipment.

    It can be worthwhile delving a little deeper into the detail of how these Turnpoints (tasks) are arranged. This may offer you greater control, make it quicker to set your device up and help you to see only waypoints that are what is relevant.





    A brief word about tasks.

    Many navigation devices now permit the uploading of pre-defined Tasks, where a Task usually comprises a Takeoff point, Start point, a number of Turnpoints, Finish point and a Landing point. Depending on the device, these Tasks may be incorporated within the waypoint file, or they may be loaded sa a separate file. If you choose to use PC/Mac software to edit your waypoint files it is important to understand where your tasks are saved if you wish to keep them.

    If you load waypoints with a different format to that used when defining your tasks, the tasks may disappear. Make backups.

    Tasks included in a SeeYou, CUP, file will be visible in SeeYou and LX devices.

  • Airspace - background info and external links.

    Airspace can be created or changed throughout the year, although big changes are relatively rare; these changes are published approximately monthly. When there is a significant permanent change within the area that you fly then it is important to mark the changes on your chart.


    For an introduction to airspace, why not take a quick look at this webpage.

    NATS Introduction to airspace.

    It is important to know what each type of airspace is, and to decide how you are likely to treat airspace for the flight you intend to make. For example, some airspace can be used if your glider has a transponder, my glider doesn't have a transponder, so I ensure that I get a warning when I am close to a TMZ, someone with a transponder may not want this warning. Some clubs have letters of agreement (eg Aboyne and Denbigh), you may wish to display airspace relating to these agreements. If you are thermal soaring In South UK you may want a warning if you reach FL100. If you are wave flying with a LOA you may want this warning inhibited.
