What is one type of Irregular Operation (IROPS) that occurs due to a high level of aircraft and passenger flow into the airport?

A surge is characterized by a sudden increase in aircraft and passenger flow, resulting in a high level of activity at the airport. This situation can lead to operational challenges, such as congestion, longer wait times, and potential delays. During a surge, the airport may experience difficulties managing resources, including staff and ground services, to accommodate the influx of passengers and aircraft.

In the context of irregular operations (IROPS), a surge highlights the importance of effective airport management and planning to ensure that safety and efficiency are maintained, even during peak flow periods. The airport's ability to adapt to such surges can prevent these peak times from excessively impacting overall operations, maintaining a smooth flow despite the increased demand.

It's also relevant to understand that other types such as "Capacity" might seem similar but they refer more broadly to the overall capability of an airport rather than the specific, often sudden increases in activity seen during a surge scenario. Likewise, "Extended Stay" and "After Hours" deal with other operational issues that do not specifically address the significant influx of traffic caused by a sudden surge in passenger and aircraft numbers.
