Definition
A formal report filed by air traffic control when an aircraft operating in oceanic airspace deviates from its assigned clearance — typically in altitude, route, speed, or time — in a way that affects separation from other aircraft. The report documents the deviation so it can be investigated and addressed.
Plain English
A written record made when an aircraft over the ocean does not fly exactly what it was cleared to fly, and the mistake matters for keeping aircraft safely apart.
Context Anchor
Seen in oceanic operations, especially after a possible route, altitude, or timing deviation during an ocean crossing.
Derivation
Oceanic refers to airspace over the open ocean, where there is no radar coverage and aircraft are tracked by position reports. Errors in this environment carry more weight than over land, because controllers cannot see the aircraft directly — so deviations are formally reported rather than just corrected on the fly.
Why Pilots Care
Filing the report allows authorities to investigate the cause of the error in radar-limited oceanic airspace and improve procedures to reduce future safety risks.
Intuition Check
Do not read “error report” as just casual paperwork or blame. In this FAA context, it is a formal safety record of a significant deviation in oceanic operations.
Example Sentence 1
After climbing to the wrong flight level without a revised clearance, the crew was informed that an Oceanic Error Report would be filed.
Example Sentence 2
Review of Oceanic Error Reports helps identify waypoint programming mistakes that occur during long flights without radar coverage.
