If number 2 is told to go to the wrong frequency, what should they do?

The appropriate action for number 2 is to go to the directed frequency and wait for number 1 to figure out the situation. In formation flying, it is essential to maintain communication, and going to the wrong frequency allows number 2 to follow instructions while still being in a position to re-establish communication once the issue is resolved. This also demonstrates adherence to crew resource management principles by ensuring that the formation remains operational and can regroup if necessary.

Going to the wrong frequency without complaint or delay is part of maintaining professionalism and situational awareness in the flying environment. If number 2 were to wait for number 1 to return or to notify ATC, it could result in miscommunication or disruption of the formation, which could compromise safety and operational efficiency. Therefore, promptly following orders while remaining situationally aware is critical in these scenarios.
