What is the speed for approach category A?

The correct answer of up to 90 knots for approach category A is based on the defined speed criteria established by the FAA. Approach categories are determined by the stall speed in the landing configuration of an aircraft, and category A is designated for aircraft with a stall speed of 30 knots or less. This means that for approach, their maximum speed can be up to 90 knots.

Understanding the categorization is essential for safe operation during an approach phase, as it helps to indicate the operational limitations and appropriate separation from other aircraft in the airport environment. Adhering to this speed category is crucial for maintaining control and ensuring a safe approach, particularly in busy airspace or during crowded approach patterns. This categorization also helps standardize procedures and expectations for pilots and air traffic control.

The other options represent speeds that exceed the limits set for approach category A. Since approach category B starts at speeds above 90 knots, it would not apply to aircraft in category A.
