What speed classification does approach category E represent?

Approach category E represents aircraft that approach at speeds greater than 165 knots. This classification is primarily used to determine the required minimums for instrument approach procedures. The category is important for air traffic control and the design of terminal procedures, as it ensures that separation standards and obstacles are appropriately managed for faster aircraft during final approach, landing, and missed approaches.

In contrast, the other speed classifications represent slower aircraft variants, which are typically in categories A through D, serving different operational needs and safety considerations at airports. Understanding these classifications helps pilots determine the appropriate approaches they may use based on their aircraft's characteristics and enhances overall safety during instrument operations.
