For extended over-water operations, what equipment and distance requirements apply for CFR 91 operations?

• A. For 91 operations, life vests within 50 nm and liferafts within 100 nm; 135 defines extended over-water as 50 nm
• B. For 91 operations, liferafts within 50 nm and life vests within 100 nm; 135 defines extended over-water as 100 nm
• C. For extended over-water operations, no equipment is required for 91
• D. For extended over-water operations, liferafts are required within 50 nm for 91

Answer: (A)

Extended over-water operations test your understanding of when survival equipment is required and how far offshore that requirement applies. In FAA rules, the distance boundary for extended over-water is defined by Part 135 as 50 nautical miles from land. When you’re operating beyond that 50 nm line, specific equipment must be on board and readily accessible: life vests for all occupants within reach and liferafts available for deployment. The arrangement described—life vests usable within 50 nm and liferafts accessible within 100 nm—matches the regulatory framework and ensures crews are prepared in the event of a ditching as you move farther offshore. The ETOW distance defined by Part 135 is 50 nm, which is why this option aligns with the rule set. Other choices either swap which equipment is required, omit equipment entirely, or misstate how far the aircraft must be from shore before those provisions kick in.
