One efficient solution, we simply need to add an optional Cities layer to our Vector Map database. This is already on the wishlist. Then you could simply enter the name of the city and it could search nearby that city lat/long. The issue as it stands today, is we use the FAA Apt database and it's listed city for the airport, many times is not that actual city. If we added a City Database, then we could optionally add city names to the Vector Mode, and use that city lat/long as a Search reference point.
This approach would actually knock out two birds with one stone. City name option to the Vector Mode, then search near a city location, and that way we would not be relying on an inaccurate Apt database from the FAA.
I'll add this to the wishlist for something to look at further.
