Definition
Information generated during a flight that describes the aircraft's operating condition and performance, including parameters such as airspeed, altitude, heading, attitude, vertical acceleration, engine settings, and control inputs. Flight data is recorded by onboard instruments or systems for monitoring, analysis, and accident investigation.
Plain English
The measurable information about how an aircraft is flying — things like how fast it's going, how high it is, which way it's pointed, and how the engines and controls are being used.
Context Anchor
Seen in flight planning, aircraft displays, flight tracking, flight data recorders, maintenance review, and post-flight analysis.
Derivation
Flight comes from an Old English word meaning the act of flying. Data comes from Latin datum, meaning “something given.” In aviation, flight data is the set of facts “given” by the aircraft, instruments, or records about a flight.
Why Pilots Care
Provides objective evidence for accident investigation, training debriefs, and maintenance decisions.
Intuition Check
Flight data does not mean every detail about a trip, such as passenger names or hotel plans. In aviation, it means information about the aircraft’s actual flight and operation.
Example Sentence 1
After the incident, investigators downloaded the flight data from the recorder to see what the aircraft was doing in the final minutes.
Example Sentence 2
Aircraft maintenance teams examine flight data to spot unusual engine readings before they become problems.
