What is aircraft performance data and how is it used in dispatch calculations?

• A. Engine horsepower is the only relevant data.
• B. Data on takeoff/landing distances, climb performance, speeds, and required runway lengths; used to determine feasibility, fuel, and safe operating margins.
• C. Cabin pressurization settings are the primary metric.
• D. Only the tail number matters.

Answer: (B)

Aircraft performance data describes how an airplane behaves under different weights, temperatures, altitudes, winds, and runway conditions. In dispatch calculations, this data is used to estimate how much runway is needed for takeoff and for landing at the planned weight, to verify climb performance and obstacle clearance, and to determine the speeds and configurations used during the flight. It also informs fuel planning, ensuring enough fuel on board for the trip, reserves, and any alternates while maintaining safe operating margins. In short, performance data links the aircraft’s capabilities to the planned conditions to prove the flight is feasible and safe. Choices that focus on engine horsepower, cabin pressurization as the primary metric, or the tail number miss the central use of this data in dispatch.
