Definition
A computer-driven process in air traffic management systems that carries out a function — such as issuing, updating, or distributing flight data — without requiring a controller or specialist to perform each step manually.
Plain English
The system does the task by itself, automatically, instead of someone having to do it by hand.
Context Anchor
Seen in FAA acronym, abbreviation, and NOTAM contraction material, especially where automated aviation information systems are being described.
Derivation
From Latin 'auto-' (self) and 'exsequi' (to carry out, follow through). Together: the system carries the task through on its own.
Why Pilots Care
Allows pilots to receive faster updates and confirmations on flight plans and changes, improving efficiency and reducing errors from manual handling.
Intuition Check
Do not read execution here as punishment or as a special flight action. In this context, execution simply means carrying out a task.
Example Sentence 1
The flight data update was handled by automated execution, so no controller had to enter it manually.
Example Sentence 2
Pilots benefit from AEX when changes to routes are executed without additional calls to ATC.
