What is meant by the term "holding pattern" in aviation?

The term "holding pattern" refers to a predetermined flight path that aircraft follow while orbiting a designated fix. This is typically used in situations where an aircraft cannot land immediately due to air traffic or runway conditions, allowing them to wait in a controlled manner until they receive clearance to descend or land. The holding pattern consists of a series of standardized turns and legs that ensure consistency and safety during this waiting period.

The concept is crucial for air traffic control, as it helps manage traffic flow in busy airspaces and provides pilots with a structured way to maintain spacing between aircraft. Holding patterns are specifically designed with prescribed entries and exits, which pilots are trained to execute, helping to ensure safety and efficiency in busy airspace systems.
