Which components comprise the practical capacity measures?

• A. Runway, taxiway and gate area
• B. Terminal seating capacity
• C. Apron area space
• D. Fuel storage capacity

Answer: (A)

Practical capacity measures are driven by the physical and operational constraints that govern aircraft movement and turnarounds. The most influential components are the runways, the taxiway network, and the gate area. Runways determine how many arrivals and departures can be processed per hour; taxiways control how efficiently aircraft move between runways and gates; and the gate area defines how many aircraft can park, be serviced, and be turned around at once. Other options don’t directly cap the rhythm of operational throughput: terminal seating relates to passenger comfort, apron space is a broader space factor but not the primary gating measure for capacity, and fuel storage affects servicing but not the immediate movement rate in the same way.
