Init A Page - Alternate Airport/Co Rte
Enables an alternate airport (four-letter ICAO code) to be entered. These fields are dashed until a primary destination is entered in line 1R. Once the primary destination has been entered, NONE is displayed in this field, which may be overwritten. Entering an alternate allows pilots to use FMGC predictions as an aid in decision making. If the airport is not in the database, the NEW RUNWAY page displays. The alternate airport can be deleted by entering NONE.
