What defines the operational characteristics of a close parallel runway?

The operational characteristics of a close parallel runway are defined by the separation distance between the runways. When the separation is less than 2,500 feet and there are no simultaneous Instrument Flight Rules (IFR) approaches allowed, this creates specific operational challenges and requirements for the management and safety of air traffic. In these scenarios, air traffic control must ensure that aircraft can safely operate without the risk of wake turbulence conflicts, as well as managing spacing and sequencing of aircraft landing on each runway.

Choosing this option reflects an understanding of how close parallel runways can be safely utilized under particular operational constraints and the aviation industry's focus on maintaining safety standards in air traffic management. The guidance is geared towards ensuring that aircraft have adequate separation to prevent incidents while still maximizing runway efficiency. This understanding is essential for individuals involved in airport operations, planning, and air traffic control.
