Approach category C is defined by the FAA in terms of a specific speed range for aircraft during the approach phase of flight, which is crucial for determining minimum separation distances and the appropriate use of navigational aids. The speed range for Category C is established as being between 121 and 140 knots calibrated airspeed (CAS). This category is primarily applicable to aircraft with a stall speed in landing configuration of between 81 and 90 knots.

Understanding the speed ranges for each approach category is essential for pilots operating under instrument flight rules (IFR), as it influences approach speeds, minimums, and separation from other aircraft. This knowledge aids in ensuring safety and efficiency during critical phases of flight. Categories are largely based on the aircraft's performance characteristics and the need to set standards for approach, landing, and takeoff.
