A Letter of Deviation is required when a vessel has what condition?

Explanation:
When essential navigation safety equipment stops operating, a Letter of Deviation is required. This document gives formal authorization and a documented rationale for why the vessel must alter its voyage plan or continue operations despite the equipment failure, until repairs are made. It ensures officials understand that the deviation is safety-driven rather than routine. If all safety gear is functioning—ARPA is operative, GPS is normal, and AIS is transmitting—the vessel can follow its planned route without needing a deviation.
