Definition
A feature in a Special Use Airspace Information Service (SUAIS) or similar tool that allows a pilot to search current scheduling data for specific Special Use Airspace (SUA) — such as Military Operations Areas, Restricted Areas, and Warning Areas — to determine whether that airspace is active, scheduled to be active, or released for civilian use during a planned flight.
Plain English
A search tool that lets you check whether a specific piece of military or restricted airspace is going to be in use when you plan to fly through or near it.
Context Anchor
Seen in FAA guidance about how civilian pilots can find information on special use airspace before or during flight planning.
Derivation
“Look up” has long meant to consult a reference source, such as a book, list, or database. “Functionality” means what a tool is able to do. Together, the phrase points to a tool’s ability to search for and show stored information.
Why Pilots Care
Provides immediate access to activation schedules, boundaries, and contact frequencies so pilots can safely plan routes around or through these areas.
Intuition Check
Do not read “look-up functionality” as looking upward out the window. In this context, it means a search feature in an information system.
Example Sentence 1
Before departure, the pilot used the SUAIS look-up functionality to confirm that the Restricted Area along the route was cold that afternoon.
Example Sentence 2
During preflight, the look-up functionality displayed the controlling agency frequency for the nearby MOA.
