What should the In-charge do after being informed by a cabin crew member about issuing a warning card?

The correct response involves entering the passenger's name and seat number on the warning card to formally document the situation. This step is crucial in maintaining proper records of any incidents onboard, as it ensures that the situation is clearly outlined should further action be necessary. Documenting the incident enhances accountability and assists in the decision-making process moving forward, whether it involves further intervention or managing ongoing passenger behavior.

While providing this information is vital, notifying other crew members, preparing for potential ejection, or waiting for signals from the Pilot in Command are actions that would generally follow depending on the situation. However, the immediate priority is to document the warning accurately, which is fundamental for ensuring the safety and order of the cabin environment. This structured approach helps ensure that all crew members are informed and prepared to handle the incident appropriately if it escalates.
