Airport Update

The Airport Update Form is used to update airport information.

This form may be used to add an airport to the airport data base or to update information for an existing airport.

NOTE: The airport database is kept in a file named Airports.dat. This file is copied to “Airports.dat.bkp” before any updates are applied.

This allows you the opportunity to back-out and recover from any changes that are made by mistake. Of course if you apply 2 changes the second backup will step on the first backup. This is just a simple safety measure that will save you from one mistake, not two.

In any case it is recommended that you backup the “Airports.dat” file before you make any updates.
