TERMINAL AIRSPACE SYSTEM CAPACITY ASSESSMENT OF MURITALA MOHAMMED INTERNATIONAL AIRPORT, IKEJA LAGOS, NIGERIA
This paper aims to assess the predictability of terminal airspace capacity. To deliver the required predictability and performance levels, it becomes imperative to determine the available LOS airport capacity effectively from daily operations time frames. Data needed for this study was collected from secondary sources- a survey of existing documents such as published flight strips of Nigerian Airspace Management Agency (NAMA). A modified version of Aviation System Performance Metrics (ASPM) of the Federal Aviation Administration (FAA) was adopted in the paper. From the findings, the levels of the daily arrival and departure utilization score for a typical week ranges from 72-87%. The trend shows that all through the week the LOS airport experiences majorly zero airport performance score between the hours of 00.00 am to 2 am, with few international arrivals and departures from the hours of 00.00 am to 4 am. But from 4.01 am till midnight every day, the LOS airport has airport performance score ranging from 44% to 100%. Hence the airport is adjudged to be slightly underutilised. However, the airport performed better on Saturday with a utilisation score of 85%, and this is closely followed by Wednesday with a score of 85%. The least performance rating was seen on Sunday with a 78% score. For LOS airport current demand exceeds capacity, terminal capacity assessments should provide a framework for the most appropriate management of capacity with excess demand, capacity assessment can highlight the options for growth and the risks of over scheduling
