Known Errors / News - 1st August 2008
1. The problem described in Documentation > Compilation Errors > para 4b is still present in databases sold for the GPS 92 and III Pilot, and is unlikely to be fixed before the units become obsolete. The work-around is to treat them as obsolete already, and use a database for a current unit.
2. I have now heard of two occasions (in12 years!) where a new database for a GPS89, GPS90 or GPSCOM190 has interfered with the software in the unit. This suggests that the max image size is a little less than I had been assuming, and that the software does not enforce the limit properly. Please beware of cramming too much in.
3. If you change the co-ordinates of an airport, the runways will move with it. This is because the thresholds are kept as offsets from the airport 'centre'. If you only wanted to move the centre, you will have to make a note of the runway threshold co-ordinates and re-enter them after changing the airport centre. I am unsure whether this is a bug or a feature, so I will regard it as a feature.
4. The USR waypoints db can now be dumped in Batch format using GPS_DBM.
5. AutoGEN fails to create batch files correctly if any part of the pathname to the files contains a space character.
6. GPS_OBS creates batch files with umlauted chars in the names, instead of converting them to OE, UE, etc, so you have to do it by hand.
7. Version 4.7.3 corrects a number of small errors, including those previously listed here for 4.7.2, and the GPSMAP495 is now supported. A new program MapSUA is included, I wrote it to help me compare "sua.all" dumps and I find it very useful, if a little unpolished.
8. We now have a number of RNAV approaches in the Americas databases which have 4 approach points (previously the maximum was 3), and this has broken GPS_GEN. The fixes can be downloaded from http://www.abnormal.com/~avia_dbm/GPS_GEN.zip and http://www.abnormal.com/~avia_dbm/G496_GEN.zip
9. Most recent atl databases have an error in the SUA section for area "SUA(b) MATHIATIS (D)-21 {Danger Area P0} 0 to 100000", so anyone wishing to recompile SUAs will have to edit this line and its single associated point out of the file. You can see the problem if you List SUAs in GPS_GEN, and/or look for it in the GPSMAP dispay page.
