Definition
The measurable capability of an aircraft during the takeoff and landing phases of flight, expressed primarily as the runway distances required to safely accelerate and lift off, or to touch down and stop, under specific conditions of weight, density altitude, wind, runway surface, and slope. These distances are published in the aircraft's performance charts and must be calculated before each flight to confirm the available runway is adequate.
Plain English
How much runway your airplane needs to get airborne and to stop after landing, given the conditions on the day. Pilots calculate this from charts in the aircraft manual before every flight to make sure the runway is long enough.
Context Anchor
Used during preflight planning and before choosing or using a runway, especially at short runways, high-elevation airports, hot-weather airports, or runways with obstacles nearby.
Derivation
The key word is “performance,” from older French and English words meaning to carry out or complete an action. In aviation, performance means what the airplane can actually do under real conditions, not just how well it seems to be flying.
Why Pilots Care
Determines whether a takeoff or landing can be performed safely on a particular runway without exceeding aircraft limits.
Grounding Statement
The same airplane may need much more runway on a hot, heavy, no-wind day than it needs on a cool, light, windy day.
Intuition Check
Do not read “performance” here as a general idea of doing well. In this context, it means the airplane’s measured ability to take off or land within the available distance under specific conditions.
Example Sentence 1
Before departing the high-elevation airport on a hot afternoon, the pilot reviewed the takeoff and landing performance charts and confirmed the runway was long enough for both departure and a possible return landing.
Example Sentence 2
Changes in temperature and wind directly affect takeoff and landing performance, requiring adjustments to the planned takeoff weight.
