Extended over-water operations are defined as operations at a horizontal distance of more than how many nautical miles from the nearest shoreline?

• A. 50 nm
• B. 25 nm
• C. 100 nm
• D. 200 nm

Answer: (A)

The test is about where the boundary lies for labeling a flight as extended over-water. Extended over-water operations start when you are more than 50 nautical miles from the nearest shoreline. This 50 NM threshold is used to trigger additional planning and safety requirements for staying farther from land, such as enhanced navigation and communication considerations and survival equipment. So, 50 nautical miles is the defining distance. The other distances don’t fit because 25 NM stays within the closer, standard category, while 100 NM and 200 NM would place you well beyond the typical extended-over-water boundary.
