Definition
A flight information bulletin published by U.S. Army Aviation to communicate aeronautical information, procedural changes, safety notices, and operational guidance to Army aviators and supporting personnel.
Plain English
An official Army Aviation newsletter-style publication that passes important flying information, updates, and safety items to Army pilots and crews.
Context Anchor
Seen in FAA glossary material and in flight planning or coordination involving Army aviation activity.
Derivation
The acronym is built directly from the title. 'Bulletin' comes from Italian 'bulletino,' meaning a short official notice — the same root used today for any brief, authoritative posting of information.
Why Pilots Care
Army aviators and controllers working with Army flights rely on these bulletins to avoid conflicts with service-specific rules that may not appear in standard FAA publications.
Intuition Check
USAFIB may look like it refers to the U.S. Air Force because it begins with “USAF.” In this glossary entry, it means an Army Aviation Flight Information Bulletin.
Example Sentence 1
The new helicopter route procedures were first announced to Army crews through a USAFIB before being added to the standard charts.
Example Sentence 2
The controller checked the USAFIB to verify Army helicopter routing procedures at the joint airfield.
