Definition
Unplanned, abnormal occurrences in flight that threaten the safety of the aircraft, its occupants, or both, and require immediate pilot action. In instrument flying, emergency events include situations such as system or instrument failures, loss of communication, unexpected loss of visual references, structural icing, engine problems, or any condition that demands prompt corrective action to maintain safe flight.
Plain English
Things that go wrong in the air and need to be handled right away to keep the flight safe.
Context Anchor
Seen in instrument training when discussing how a pilot should respond to serious problems while flying by reference to instruments.
Derivation
From the Latin emergere, meaning 'to rise out' or 'come forth.' An emergency is something that suddenly arises and demands attention. Pairing it with 'events' simply names these as specific occurrences a pilot must recognize and respond to.
Why Pilots Care
Recognizing and responding correctly prevents loss of control and supports safe recovery.
Grounding Statement
An emergency event is the point where the pilot must switch from normal flying to protecting the flight from immediate danger.
Intuition Check
Do not read emergency events as meaning only crashes. In aviation, an emergency event can be any serious situation that demands immediate or priority action, even if the aircraft is still flying.
Example Sentence 1
The chapter on emergency events covers what to do if the attitude indicator fails while flying in cloud.
Example Sentence 2
Training covers responses to common emergency events so pilots act without hesitation.
