Definition
In aviation usage, the official power or permission granted by a regulatory or controlling body (such as the FAA or ATC) to issue, approve, or enforce an action, clearance, procedure, or document. It can also refer to the body itself that holds that power.
Plain English
The official right to allow, decide, or require something — or the agency that holds that right.
Context Anchor
Seen in NOTAMs, airport notices, and FAA reference material when space is limited and the approving or controlling source needs to be identified.
Derivation
From Latin auctoritas, meaning 'power, command, or right to act,' from auctor ('originator, master'). The aviation use keeps this core idea: the entity or permission that originates and backs an action.
Why Pilots Care
It determines exactly what actions a pilot is allowed to take without violating regulations or airspace rules.
Intuition Check
Authority does not mean personal confidence here. It means official permission or the person or organization that has the legal right to control or approve something.
Example Sentence 1
The NOTAM stated that special VFR operations were not AUTH within the Class B airspace during the event.
Example Sentence 2
Review the NOTAM to confirm any AUTH requirements before entering the restricted area.
