What is the speed restriction category for Category C aircraft?

The speed restriction category for Category C aircraft is set at 121-140 knots. This categorization is based on the aircraft's approach speed, which is critical for determining separation minima between different types of aircraft. Category C aircraft are typically larger and have higher approach speeds than Category A and B, but their speeds do not exceed that of Category D.

The classification helps air traffic controllers manage traffic effectively and ensures that aircraft maintain appropriate spacing during approach and landing phases. This allows for safe operations, particularly in busy airspace where various aircraft types may be operating simultaneously. Understanding the speed categories helps pilots and controllers maintain safety and efficiency in their operations.
