What initial step should be taken during a tail strike situation?

In a tail strike situation, the proper initial response involves ensuring that the crew is promptly made aware of the issue to assess the situation and take necessary actions to maintain safety. The correct approach is for No.2 to contact No.1 to inform them of the tail strike. This communication is crucial because immediate awareness allows the flight crew to evaluate the aircraft's condition, verify any potential damage, and prepared for possible emergency procedures that may need to be enacted.

Additionally, this approach promotes effective crew resource management since it fosters clear communication between cabin and cockpit crew. No.1 receives the critical information in a timely manner, which is essential for operational safety and ensures that both parties are aligned in their understanding of the situation. Keeping the crew informed enables them to work together collaboratively to prevent further issues and execute any necessary safety protocols.
