The Airport Capacity Enhancement Plan (ACEP) is a strategic plan implemented by airports to optimize their existing infrastructure and increase their capacity to accommodate growing air traffic demand. The plan aims to enhance the airport's ability to handle more flights, passengers, and cargo while maintaining safety, efficiency, and reducing delays.

The ACEP typically involves a combination of short-term and long-term initiatives, which may include:

1. Airfield modifications: Upgrading runways, taxiways, and aprons to improve airfield efficiency and reduce congestion.
2. Terminal expansion: Enhancing terminal buildings to increase passenger processing capacity, including check-in, security screening, and baggage handling.
3. Gate and apron expansion: Adding more gates and apron space to accommodate additional aircraft, reducing the need for remote parking and improving aircraft turnaround times.
4. Air traffic control (ATC) modernization: Implementing advanced air traffic management systems, such as automation and surveillance technologies, to optimize air traffic flow and reduce delays.
5. Slot allocation and scheduling: Implementing more efficient slot allocation and scheduling practices to minimize congestion and reduce the likelihood of delays.
6. Ground handling and logistics: Improving ground handling processes, including baggage handling, cargo handling, and fueling, to reduce aircraft turnaround times and increase overall efficiency.
7. Technology integration: Leveraging technologies like artificial intelligence, biometrics, and data analytics to enhance passenger experience, improve security, and optimize airport operations.
8. Collaboration and coordination: Fostering collaboration among airport stakeholders, including airlines, ground handlers, and regulatory bodies, to ensure a coordinated approach to capacity enhancement.

The Airport Capacity Enhancement Plan is essential for airports to:

1. Meet growing demand for air travel and cargo transportation.
2. Improve passenger experience and reduce congestion.
3. Increase airport efficiency and reduce delays.
4. Enhance safety and security standards.
5. Support economic growth and development in the surrounding region.

By implementing an effective ACEP, airports can ensure that they are well-equipped to handle the increasing demands of air travel, while maintaining a high level of safety, efficiency, and customer satisfaction.
