Critical infrastructure guide
Airports as Infrastructure Systems
Runways, terminals, fuel, navigation, security, power and ground access as one network.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Runways, terminals, fuel, navigation, security, power and ground access as one network.
Core system ideas
Airport service depends on more than runways: power, communications, fuel, weather information and ground access are essential.
Capacity can be constrained by terminals, gates, airspace or ground handling.
Recovery planning must coordinate many independent organizations.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
