The IT network of an airport: separate zones for passenger Wi-Fi, common-use terminal equipment, operations systems and airline links.
Drawing diagram…
Network topology for an airport: a core network in the airport data centre connects zones separated by firewalls: passenger Wi-Fi (internet only), common-use terminal equipment (CUTE check-in desks, kiosks, boarding gates) linked to airline departure control systems via the SITA network, the operations zone (AODB, FIDS, baggage handling system), and the security zone (CCTV, access control). The baggage handling PLC network is isolated further.

ACS --- COREThe journey of a checked bag through an airport: check-in, security screening, sorting to the right flight and loading, with exceptions.
How a maintenance work order moves in an airline MRO: from a pilot's defect report to inspection, parts, repair and certificate of release to service.
The systems that run an airport day to day: operational database, resource management for gates and stands, flight information displays and collaborative decision-making.
How flight data moves around an airline's operations: flight planning, the aircraft's ACARS messages, flight data monitoring and crew reports.
A monthly crew planning cycle for an airline: pairing construction, bidding, roster publishing and day-of-operations changes.
The coordinated steps on the ground between arrival and departure: deboarding, cleaning, fuelling, catering and boarding.
