Definition
Performance charts in the Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM) used to determine the takeoff distance required for an aircraft under given conditions, typically accounting for pressure altitude, temperature, aircraft weight, headwind component, and runway surface. Most takeoff charts provide both ground roll distance and total distance to clear a 50-foot obstacle.
Plain English
Tables or graphs in the aircraft's manual that tell the pilot how much runway will be needed to take off on a given day, based on the conditions at the airport and the weight of the aircraft.
Context Anchor
Seen in aircraft performance planning before flight, especially when checking whether the available runway is long enough for takeoff.
Derivation
Takeoff combines the everyday idea of taking something away with the aircraft sense of leaving the ground. Chart comes from an old word for a paper or map; in aviation, it means information arranged so a pilot can read and use it quickly.
Why Pilots Care
Using takeoff charts verifies that the aircraft can become airborne before the runway ends and that obstacle clearance is possible, directly preventing runway overruns and loss-of-control accidents.
Grounding Statement
Before takeoff, the pilot compares the airplane, weather, and runway conditions against the chart to see what performance to expect.
Intuition Check
Do not read takeoff charts as general suggestions or best-case promises. They are performance planning tools based on stated conditions, and the pilot must match those conditions to the actual flight as closely as possible.
Example Sentence 1
Before departing the high-elevation airport on a warm afternoon, the pilot consulted the takeoff charts and confirmed the required ground roll was well within the runway available.
Example Sentence 2
A headwind shown on the takeoff charts reduced the calculated ground roll by several hundred feet.
