Question

When a __________ or degraded indication is present with increased vibrations, switch off AVCS and continue flight with AVCS on or off to achieve minimum vibration."

Answer 1

The question is related to aviation engineering, focusing on the use of the AVCS in reducing aircraft vibrations. If there is an indication of abnormal system operation with increased vibrations, the recommendation is to switch off the AVCS and continue flight to achieve minimum vibration.

Step-by-step explanation:

The query appears to be referencing procedures related to aircraft operation, specifically the use of an Active Vibration Control System (AVCS). When an abnormal or degraded indication in an AVCS is observed in conjunction with increased vibrations, it is recommended to turn off the AVCS. The goal is to continue the flight, either with the AVCS turned off or back on if it results in the minimum vibration. Essentially, the system is designed to reduce vibration levels in aircraft to improve comfort and reduce structural stress. If the system isn't functioning correctly, it could contribute to excess vibration instead. It's important for flight crews to understand how to manage AVCS settings to maintain a safe and comfortable flight.
