Which of the following is a characteristic of Class C and D airports regarding speed restrictions?

The characteristic of Class C and D airports indicating that a 200-knot speed restriction extends 4 nautical miles (nm) from the airport is accurate because it pertains to the operational regulations surrounding air traffic management in these types of airspace.

Class C and D airports are characterized by controlled airspace, where speed regulations are put into place to maintain safe separation between aircraft, especially in busy airport environments. The 200-knot speed limit is typically enforced when aircraft are below 2,500 feet within 4 nautical miles of the airport, as a measure to enhance safety and reduce the risk of collisions in areas with significant air traffic.

This specific speed restriction helps mitigate the potential for conflicts among numerous aircraft arriving and departing, thus ensuring a more orderly and systematic approach to handling air traffic in these zones. Adherence to this speed limit allows air traffic controllers to manage aircraft movements more effectively and aids pilots in maintaining situational awareness in busy airspace.

Other options do not accurately reflect the regulations or safety measures in place at Class C and D airports. For instance, the assertion that there are no speed restrictions is incorrect because controlled airspace specifically imposes speed limits to enhance safety. Similarly, stating that speed restrictions apply only to takeoff overlooks the
