Plain English Meaning
DINS is a military-run website where pilots look up the latest NOTAMs — short bulletins about closed runways, broken lights, taxiway work, or anything else that affects an airport — before they fly.
Full Definition
A U.S. Department of Defense web-based system that provides current Notices to Air Missions (NOTAMs) for military and joint-use airfields, as well as access to NOTAMs for civil airports worldwide. Pilots use DINS to retrieve official preflight NOTAM information for flight planning.
Context Anchor
Seen when checking airport information, airport diagrams, and temporary changes that may affect whether a runway, taxiway, light, or procedure is usable.
Derivation
Defense refers to the U.S. Department of Defense, which runs the service. Internet indicates it is delivered through a website rather than a phone briefing. NOTAM stands for Notice to Air Missions — short for the official bulletins about temporary changes at airports or in the airspace system.
Why Pilots Care
Provides quick access to time-sensitive safety information that can affect runway availability, procedures, or airspace restrictions.
Intuition Check
Do not read DINS as a chart or airport diagram itself. It is a source for current notices that may change how the airport information should be used.
Example Sentence 1
Before her cross-country flight into a joint-use field, she pulled the latest NOTAMs from DINS to check for runway closures.
Example Sentence 2
She found a runway closure notice on DINS that changed her choice of alternate airport.
