Which of the following is NOT a part of capacity analysis?

Capacity analysis in the context of airport operations primarily focuses on evaluating the various components that contribute to an airport's ability to accommodate aircraft and passengers. This includes aspects such as airspace, airfield, and terminal facilities, all of which play a crucial role in determining how efficiently an airport can function.

Airspace is essential in capacity analysis because it encompasses the volume of air traffic that can safely operate in a given area, directly impacting the flow of aircraft in and out of the airport. The airfield, which includes runways and taxiways, is critical as it dictates how many takeoffs and landings can occur simultaneously or in a given timeframe. The terminal also plays a significant part because it is where passengers embark and disembark; its design and capacity can affect how smoothly operations run on the ground.

In contrast, aircraft manufacturing is not directly related to the operational capacity of an airport. While it plays a role in the broader aviation industry, it pertains to the production of aircraft rather than the analysis of an airport's ability to serve air traffic. Therefore, it is excluded from the components typically analyzed in capacity assessments.
