Definition
An abbreviation used on charts, in flight publications, and in avionics displays to indicate a procedure — a defined, step-by-step sequence of actions flown or performed in a specific order, such as an instrument approach procedure, departure procedure, or missed approach procedure.
Plain English
A short way of writing the word 'procedure' — meaning a set series of steps to follow.
Context Anchor
Seen in FAA abbreviation lists, chart notes, flight notices, checklists, and other operational text where space is limited.
Derivation
From the Latin procedere, meaning 'to go forward.' A procedure is literally a way of going forward step by step. In aviation, it points to a published, repeatable sequence pilots are expected to follow exactly.
Why Pilots Care
Following published procedures ensures compliance with regulations and ATC while reducing errors during high-workload phases of flight.
Intuition Check
Procedure does not mean a casual habit or a loose suggestion here. In aviation, it means a defined set of steps to follow.
Example Sentence 1
The pilot pressed the PROC button on the GPS to load the instrument approach procedure for the destination airport.
Example Sentence 2
ATC issued a clearance for the published departure procedure.
