Clearance delay什麼意思
"Clearance delay" is a term used in the context of air traffic control and aviation. It refers to a situation where there is a delay in obtaining the necessary clearance or permission from air traffic control for an aircraft to take off, land, or proceed to its next destination.
This delay can be caused by various factors, such as:
- Heavy traffic at the airport or in the airspace, which leads to a backlog of aircraft waiting for clearance.
- Congestion in the air traffic control system, making it difficult for controllers to handle the volume of requests promptly.
- Weather conditions that require special clearances or cause delays in flights.
- Technical issues with the aircraft or air traffic control equipment.
- Security concerns or other safety-related issues that require additional clearances or procedures.
When an aircraft experiences a clearance delay, it means that the pilot has to wait for instructions from air traffic control before the next phase of the flight can begin. This can lead to longer wait times on the ground, in the air, or at the gate, and can sometimes cause disruptions to flight schedules.
In the context of ground transportation or other non-aviation situations, the term "clearance delay" might be used metaphorically to refer to any situation where there is a delay in obtaining permission or approval to proceed with a planned action or activity.
