At what category would an aircraft with a speed of 121-140 KTS fall?

An aircraft with a speed of 121-140 Knots falls into Category C based on the aircraft's stall speeds in landing configuration with flaps extended. This classification system is primarily used to facilitate safe separation of aircraft during operations, particularly in terms of approach and landing speeds.

Category A applies to aircraft with a stall speed of less than 61 knots, while Category B ranges from 61 to 130 knots. Category C covers those with a stall speed of 131 to 140 knots, making it the appropriate classification for an aircraft with a speed within the 121-140 knots range.

Understanding these categories is important for pilots because they must be aware of the different performance characteristics of various aircraft types to ensure safe and efficient operations in controlled airspaces. This categorization helps in managing wake turbulence, approach speeds, and overall traffic flow in busy airspace settings.
