Definition
The published numerical information that describes how a specific aircraft will perform under defined conditions, including takeoff and landing distances, climb rates, cruise speeds, fuel burn, service ceiling, and weight and balance limits. This data is found in the Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM) and is determined by the manufacturer through flight testing.
Plain English
The numbers that tell you what your aircraft can and cannot do — how far it needs to take off, how fast it climbs, how much fuel it burns, and how much weight it can carry — under given conditions like temperature, altitude, and weight.
Context Anchor
Seen during flight planning, lesson planning, and preflight decisions where the pilot must decide whether the aircraft can safely complete the planned flight.
Derivation
Performance comes from older French and English words meaning to carry out or complete an action. Data comes from Latin meaning things given. Together, aircraft performance data means the given information about what the aircraft can actually carry out in flight or on the runway.
Why Pilots Care
Using accurate performance data prevents runway overruns, insufficient climb capability, and other performance-related accidents by confirming the aircraft can meet the demands of the intended operation.
Intuition Check
Do not read performance as a general opinion that the airplane is good or bad. In this context, performance means specific measured or published capabilities under specific flight conditions.
Example Sentence 1
Before departing from the high-elevation airport on a hot afternoon, she checked the aircraft performance data to confirm the runway was long enough for takeoff.
Example Sentence 2
During the scenario-based lesson, the student adjusted the aircraft performance data for a hot, high-density altitude day and determined a go-around was the safer choice.
