A multi-engine aircraft capable of level flight with a failed engine can legally fly how far over water without a life raft or pressurized cabin?

A multi-engine aircraft capable of level flight with a failed engine can legally fly how far over water without a life raft or pressurized cabin?

• A. 50 miles
• B. 200 miles or 60 min distance at cruising speed, whichever is lesser
• C. 100 miles or 30 min distance at cruising speed, whichever is lesser
• D. 200 miles or 30 min distance at cruising speed, whichever is more

Answer: (B)

When a multi-engine aircraft flies over water with one engine failed and there is no life raft or pressurized cabin on board, there must be enough fuel endurance to reach land within a defined safety margin. The rule sets the maximum distance you may legally fly over water as the lesser of two values: 200 miles or 60 minutes of flight at cruising speed. This accounts for both how fast you’re going and how long you can stay aloft on the remaining engine’s fuel. If you’re flying very fast, the 200-mile limit is the controlling factor; if you’re slower, the distance you can cover in one hour becomes the limiting factor. Thus the permitted range is whichever is smaller between those two. That’s why the correct answer states the limit as 200 miles or 60 minutes at cruising speed, whichever is lesser. The other options don’t match the specified endurance-time rule.
