Yes - those freqs are good for today and most likely the entire incident since they are the extended attack freqs. There’s an additional victor of 118.725 allocated to the incident by the FAA, but it isn’t on today’s 205. It might become a future briefing or air cmd between AA and Helco if incident complexity grows.
Typically only the CMD channels might change when a team comes on board and looks at the combination of incident duration and growth, and the existing CMD fixed-infrastructure. Fixed infrastructure is ideal for the first few days of extended but if there aren’t other options for new incidents that go extended in the area, they’ll order up a NIFC cmd system to free up the fixed-infrastructure.
