What is the definition of "holdings" in commercial flight operations?

Holdings in commercial flight operations refer to predetermined aircraft flight paths that are used primarily to manage air traffic, especially in situations where an aircraft might need to wait for clearance to land or to ensure safe spacing between aircraft. These holding patterns are established routes where planes can circle and maintain a specified altitude until they receive further instructions from air traffic control.

These patterns are important for maintaining order and safety in busy airspace, allowing for efficient flow of air traffic. The use of holding patterns helps prevent congestion and potential conflicts between aircraft, ensuring that flights can be managed effectively during peak times or in adverse conditions.

The other concepts related to emergency landings, airport approach patterns, and communications protocols involve different aspects of aviation operations but do not directly define "holdings" as understood in air traffic management. For instance, while approach patterns are crucial for landing, they do not encapsulate the broader aspect of holding as it relates to air traffic control and managing positional waiting.
