If an inaccuracy is recognized by the specialist being relieved after they have relinquished position responsibility, who should they notify?

The correct choice in this scenario is to notify the relieving specialist. After a controller has relinquished their position responsibility, any inaccuracies identified should be communicated directly to the individual who has taken over that position. This is crucial because the relieving specialist is now in charge of monitoring the air traffic and ensuring safety. By informing them of any concerns, it allows the new specialist to take appropriate action to rectify the situation or apply the necessary precautions.

Notifying the supervisor might seem logical, but it is more direct and effective for the controller to address the issue with the relieving specialist who is currently responsible for that airspace. Likewise, informing the relieved specialist or the aircraft involved would not be appropriate at this point, as operational responsibility lies with the relieving specialist who needs to be immediately apprised of any inaccuracies to ensure continued safety and efficiency in air traffic management.
