What does "Performance Data" encompass?

"Performance Data" encompasses the performance metrics associated with aircraft operations, specifically focusing on calculations like takeoff and landing distances that are influenced by various conditions such as aircraft weight, altitude, weather, and runway length. This information is critical for flight planning and safety, ensuring that the flight crew can make informed decisions about the capabilities of the aircraft in different scenarios. Accurate performance data allows pilots to assess whether the aircraft can safely operate under specific circumstances.

While calculations related to fuel consumption are significant for overall operational efficiency and cost management, they fall under a different category. Records of pilot proficiency are crucial for maintaining safety standards and ensuring that pilots are qualified, but this information does not directly relate to the aircraft's performance metrics. Operational procedures for flight planning, while important, do not specifically define performance data as they focus more on the processes and protocols involved in preparing for a flight rather than the measurable performance characteristics of the aircraft itself.
