What is the difference between maintenance of way (MOW) and maintenance of equipment (MOE) in airport operations?

• A. MOW handles baggage handling; MOE maintains passenger seating
• B. MOW maintains runways and taxiways surfaces; MOE maintains airport equipment and vehicles; both are essential
• C. MOW maintains terminal lighting; MOE maintains control towers
• D. MOW schedules flights; MOE ensures customer service

Answer: (B)

The key idea here is distinguishing two areas of maintenance that keep airport operations safe and running: the physical surfaces and the equipment that supports those operations. Maintenance of way focuses on the airfield itself—runways, taxiways, and aprons—plus related infrastructure like surface markings, lighting, drainage, and signs. It’s about ensuring the pavement and its features are in good condition so aircraft can move safely.

Maintenance of equipment is about the tools and machines used to run the airport day to day—ground support equipment and vehicles like belt loaders, baggage tugs, de-icing trucks, fueling trucks, and other on‑airport machinery. Keeping this equipment in good working order prevents delays and breakdowns that can shut down operations or slow service.

Both areas are essential because safe aircraft movement depends on well-maintained surfaces, while efficient operations depend on well-maintained equipment. The other options mix in terminal services or operational tasks that aren’t about the maintenance categories described here.
