What aircraft category is assigned a speed range of 91-120 KTS?

The correct answer reflects the standard classification of aircraft based on their maximum design speed. In aviation, aircraft are categorized into various groups, primarily focusing on their performance capabilities, including speed. The category assigned to a speed range of 91-120 knots is typically categorized as Category B. This range is significant, as it helps in determining the appropriate separation and operational procedures for different types of aircraft during both takeoff and landing phases.

Category B generally includes a variety of light and medium-sized aircraft that are capable of operating efficiently within this particular speed spectrum. Understanding these categories is crucial for pilots in adhering to air traffic control guidelines as well as for flight planning purposes. This speed classification contributes to safety protocols by ensuring that aircraft operate within their designated limits, thus reducing the risk of accidents or incidents during various phases of flight.
