Which condition requires dispatcher notification specifically because it would affect fuel reserves at destination?

The key idea is that crew and dispatcher must guard against arriving with insufficient fuel according to regulatory minimums. If any change would leave the flight with less fuel than the required FAR minimum reserves at destination (or at the designated alternate), that triggers the need to notify dispatch. The dispatcher then can adjust the plan—such as altering routing, diverting to a closer alternate, or arranging additional fuel—to ensure the reserves meet the required minimums and safety margins are preserved. Other changes like large lateral or altitude deviations or a delay in ETA can affect operations or ATC coordination, but they don’t by themselves indicate a failure to meet the regulatory fuel reserves at destination.
