Factors involved in capacity analysis include:

• A. Airspace, Airfield, Terminal, Ground Access
• B. Airspace, Weather, Fuel, Runway length
• C. Airfield, Terminal, Staffing, Equipment
• D. Ground Access, Passenger demand, Ticket pricing, Airline competition

Answer: (A)

Capacity analysis in aviation focuses on the four interconnected parts of the system that truly constrain how much can be handled: airspace, airfield, terminal, and ground access. Airspace capacity determines how many aircraft can be safely sequenced in the arrival and departure corridors, governed by air traffic control procedures, sector loads, and separation standards. Airfield capacity looks at how many operations the runway system and associated taxiways can support, affected by runway configuration, wake turbulence considerations, and the time aircraft spend on the ground or taxiing. Terminal capacity addresses how many passengers can be processed through check-in, security, immigration, baggage handling, and waiting areas, which depend on facility space, staffing, and throughput rates. Ground access capacity covers the transportation links to and from the airport—roads, intersections, parking, and public transit—since bottlenecks there can prevent passengers from arriving or departing efficiently even if airside capacity is high. The other options mix factors that either influence capacity in a narrower way (like weather or runway length) or describe demand and operational resources, but they don’t collectively represent the four broad capacity-controlling areas that the analysis centers on.
