Flight Information Publications Program
The Flight Information Publications (FLIP) Program uses the concept that there are
basically three separate phases of flight: flight planning, enroute operations, and
terminal operations.
FLIP Planning
The FLIP Planning document is intended primarily for use in ground planning at base
operations offices. It is arranged into four sections: (1) General Planning, (2) Area
Planning, (3) Special-Use Airspace, and (4) Military Training Routes, North and South
America. These books may be revised between publication dates by a Planning Change
Notice (PCN) on a scheduled basis or an Urgent Change Notice (UCN) as required. A
PCN or UCN may contain a consolidation of various changes and/or corrections to
several pages of a book to preclude publishing individual replacement pages. Table 2-4
gives a brief description of the books and charts.
