abort sequence
Emergency stop procedure
An abort sequence is a predetermined series of actions to safely terminate an operation that has gone wrong or cannot continue.
The term comes from aerospace, where spacecraft and rockets have abort sequences to protect crew during launch failures: The flight director initiated the abort sequence when the engine malfunctioned.
The concept extends to computing and other technical fields where complex processes need orderly shutdown procedures rather than abrupt termination.
