Airspace Files. UK Airspace files are available from http://soaringweb.org/Airspace/UK/, in both OpenAir (Winpilot) and SUA formats.

However, for a more flexible approach, I recommend Geoff Brown's compilation via the link http://soaringweb.org/Airspace/UK/ASSelect.html

There are also some problems in using files with Glide Navigator II, StrePla and Soar Pilot Software. These can be overcome by using Geoff's facilities to limit the file size.

Some Notes on various .CUB Airspace files.
One or two incidents have been reported about .CUB files not being usable.

Initially CUB was a proprietary SeeYou format. It was binary for Copyright Reasons. CUB was recognised as a valid airspace format even though it is nothing more than a binary representation of text data.

At some point LX Navigation decided they wanted to support CUB format in their products because many competitions were publishing CUB formatted airspace files and other file types that were not supported by LX. Due to some problems with the Memory Management, LX could not use the CUB files directly and decided to change the alignment of the data in the CUB format. In addition to that LX added a feature to export to CUB format from the LX Browser. Even though the format was not the same as the original, they published their files as CUB - and this is the problem. There are in essence two different formats sharing the same file extension.

The problem has not been caught immediately because SeeYou on the PC had no problems reading both file types regardless of the data alignment. This was unfortunately not true for SeeYou Mobile/Windows CE. Different alignment causes completely unpredictable results in old versions of SeeYou Mobile. Due to this unpredictability (and totally useless airspace warnings as a result) Naviter added an error message in SeeYou Mobile (Error loading file C:\filename) if the file has bad alignment.

Unfortunately there is no easy way of finding out which version of the CUB file you have, and it would seem that there is no way that the two formats can be brought into line with each other, however loading an unknown CUB file into SeeYou for PC and then exporting it using the SeeYou Mobile Wizard (Ctrl+F9) will produce a CUB file usable by SeeYou Mobile.

The whole issue is further confused by there being two companies with similar names.

In general, LX Navigation use LX format files whereas LXNAV use Naviter Format Files.

Caveat Emptor!

Adding the Waypoint Code to Waypoint Names in CUP files.

Adding the Waypoint Code to the front of Waypoint Names will make the selection of Waypoints easier with some recorders. Thus, Aboyne Bridge becomes AB1-Aboyne Bridge.
While this is possible using Excel, this can be a bit cumbersome. To ease the process, a program has been made available to do this task for you.

UK National Grid.

UK Ordnance Survey maps are constructed using the OSGB36 Geodetic Datum, but IGC requires all Flight Recorders to be set to the WGS84 Datum. A conversion program to convert between UK Ordnance Survey Grid References and Lat/Longs (both OSGB36 and WGS84 Datums) can be accessed from http://www.newportpeace.co.uk/software/convert.zip.

Competition Goodies.

Measuring distances for Manual Scoring in Competitions can be a pain, but there is a simple program below to take the work out of it (BGA Competitions only).

Printing Grid Lists (needs SeeYou Version 8). Here is a simple program to take the work out of it (BGA Competitions only).

Flight Recorder Serial Numbers. Many of the older Flight Recorders have decimal serial number (base-10), wheras what is generally used is Alpha-numberic Serial Numbers (Base-36). Here is a simple program to convert from Base10 serial numbers to Base36 serial numbers.
