For extended over-water operations, what offshore distance triggers vest and liferaft requirements for 91 operations and how does this compare to 135 operations?

• A. For 91 operations, life vests within 50 nm and liferafts within 100 nm; for 135 operations, extended over-water is defined as 50 nm
• B. For 91 operations, liferafts within 50 nm and life vests within 100 nm; for 135 operations, extended over-water is defined as 100 nm
• C. For both 91 and 135, extended over-water is 50 nm
• D. No offshore equipment is required for 91 or 135 operations

Answer: (A)

The main idea is how far from shore you are determines what safety gear you must have during extended over-water flight, and the rules differ between 91 and 135 operations. For 91 operations, life vests must be on board and accessible within 50 nautical miles of shore, while liferafts must be aboard within 100 nautical miles. This reflects the idea that liferafts are heavier and used for longer over-water scenarios, so they’re required farther out, whereas vests cover shorter-range safety. For 135 operations, extended over-water is defined as 50 nautical miles, meaning the boundary for applying the extended over-water equipment rules is closer, using a single threshold rather than the two-tier distances used for 91 operations. This combination matches option A.
