Definition
A series of aeronautical publications produced by the National Geospatial-Intelligence Agency (NGA) for the U.S. Department of Defense. DoD FLIP includes en route charts, approach plates, airport diagrams, and flight planning documents covering U.S. and worldwide airspace. Although produced for military use, these publications are also used by civilian pilots, particularly for international and overseas operations where FAA charts are not published.
Plain English
A set of flight charts and aeronautical information books made by the U.S. military for use anywhere in the world. Pilots flying internationally often use them because they cover places FAA charts do not.
Context Anchor
Seen in flight planning, military aviation operations, and references to publications used by Department of Defense aircrews.
Derivation
FLIP stands for Flight Information Publications. The U.S. military needed a single, standardized set of aeronautical documents covering the whole world for its global operations, and that family of publications became known by the FLIP acronym.
Why Pilots Care
Military pilots depend on these publications for accurate, current information that directly affects mission safety and compliance.
Intuition Check
FLIP does not mean a flying maneuver or turning something over. Here it is an acronym for a set of official flight information publications.
Example Sentence 1
Before her flight to Europe, she pulled out the DoD FLIP en route charts to plan the oceanic crossing.
Example Sentence 2
DoD FLIP approach plates include details not always found in civilian publications.
