What is the 60 minute rule for flying?

Years ago, piston engines were undependable. Because of this, twin-engine aircraft were required to fly in range of a suitable airport for landing. In 1953, the FAA imposed what is known as the “60-minute rule” on two- and three-engine airplanes, disallowing them to fly more than 60 minutes outside the closest airport.

For example, if an aircraft is certified for 180 minutes, it is permitted to fly any route not more than 180 minutes' single-engine flying time to the nearest suitable airport.

As long as the plane has communication to ATC or other planes, the pilot would report the problem and his/her next cause of action. This would include the intention to divert to the closest airport or to do an emergency water landing if there is no other option.

ETOPS is an acronym that stands for “Extended-range Twin-engine Operational Performance Standards.” The standards determine how long an aircraft can fly from a diversionary airport with only one operable engine in the event of an emergency.

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

Today, the best ETOPs certification record is 370 minutes, for the Airbus A350, powered exclusively by the Trent XWB. This maximum diversion time, of six hours and 10 minutes, is equivalent to a maximum diversion distance of 2,500 nautical miles (4,630 km), a civil aviation industry record.

The real answer is because going north may actually provide a shorter route. This is called Great Circle Navigation. Because of the curvature of the Earth, the shortest route between two locations may appear much longer on a flat map.

Why? Answer: The maneuver you describe is usually either a 360 degree turn issued by the air traffic controller to increase spacing between your flight and another airplane, or it was one turn in a holding pattern. The one turn in a holding can occur when the expected hold time is reduced, requiring only a single turn.
