Coordinating maintenance on NAVAIDs and radars requires clear, timely communication with Flight Service and all facilities that rely on those systems so safety isn’t compromised and operations aren’t disrupted. The Airfield Facility Manager must share the planned outage window, confirm who will be affected, arrange any necessary backup procedures or traffic adjustments, and ensure everyone knows how to respond during the outage. This coordination also often involves notifying pilots and potentially issuing notices to airmen or similar advisories so everyone can plan accordingly.

Five hours provides a practical margin to complete this coordination: you have enough time to confirm the schedule with all stakeholders, line up any necessary support or contingencies, and disseminate the information through the appropriate channels. Shorter lead times, like one or two hours, increase the risk of miscommunication or unpreparedness, and four hours can still leave gaps in coordination or contingency setup.
