Hi All, Just in time for the holiday season, I've made a couple of improvements on my website: - If your device's memory is too small to accommodate the airspace map of the entire country, you can now create a subset file for just your area of interest. Start by running a query on US...

If you have an old Garmin recreational receiver just lying around, like an eTrex or a GPS 76, you may be interested to know that (with some effort) it is totally possible to load an up-to-date airspace map and airport/waypoint list on it. These can make great back-up navigators in case you lose...

Here are a couple of things I've been asked about several times. I thought I would post here for wider distribition: Hint #1 - If your glide computer or PNA can't handle the airspace file for the entire US, consider making a custom extract of a smaller region. Here is how you do it: 1. Go to...

Yesterday I noticed that someone was having trouble running a NASR database query on my website centered on Palo Alto, using a .CUP turnpoint file from Hollister. The problems had to do with some unexpected slight irregularities in the uploaded .CUP file. Today I made my website a little more...
