During flight, if the N2 becomes incapacitated, what is the procedure?

In a situation where the N2 becomes incapacitated during flight, the appropriate procedure would involve the remaining components adjusting their functions accordingly to ensure continuity and safety of the operation.

The correct answer is justified because if N2 is incapacitated, N1 would typically maintain its position, providing stability to the flight. Meanwhile, the system may allow N3 to take over the functions of N2, ensuring that operational integrity remains intact. Additionally, it's likely that N4 would also retain its position to continue executing its role.

Therefore, since each option reflects a part of the response required when N2 becomes incapacitated, stating that all options apply captures the holistic response to the failure of N2. This reflects standard operational procedures in aviation where redundancy and adaptability are crucial for maintaining flight safety.
