We have now added a comprehensive list of over 43,400 airports and 11,100 navaids across 242 countries to the FlyLogical iNavCalc global database. This enables you to plan your flight anywhere in the world via the iNavCalc email subject-line command interface, or the GoogleMaps web-browser interface. The global aviation data is courtesy of ourairports.com, a very useful (and free) community-maintained aviation web resource. If you wish to add or edit any entries, you can do so directly via ourairports.com. We will refresh the FlyLogical iNavCalc database routinely, based on the updated ourairports.com database.
Here are some screenshots taken from the FlyLogical iNavCalc GoogleMaps web app illustrating the newly-added airports and navaids (just visit flylogical.com to get started).
