What is the designated speed for Aircraft Performance Category A?

• A. 80 kt
• B. 85 kt
• C. 90 kt
• D. 95 kt

Answer: (C)

The designated speed for Aircraft Performance Category A is the standardized reference speed used in performance calculations. It is set at 90 knots to provide a consistent, safe basis for planning takeoff, climb, and landing performance while maintaining an adequate margin over stall speeds. This value helps ensure predictable handling and regulatory compliance across typical Category A operations.

The other speeds don’t serve as this standard reference for Category A; they would correspond to different contexts or performance settings, whereas 90 knots is the established figure for this category.
