How do I add a navaid to an airport? For example, the FAA has removed the NDB RWY 20 approach for KALW from its terminal approach database. I however still have the approach plate for it and would like to add the TRINA (freq: 353) back to its old location so that I can continue to fly that approach.
This scenario will happen regularly as NDBs are phased out. Since I have a number of these NDB approaches, I would like to know how to configure XP11 to be able to continue using these.
