What is required when listing an ETOPS alternate airport greater than 180 minutes?
(4) For these operations, the airplane-engine combination must be type-design-approved for ETOPS greater than 180 minutes. (2) The operator must designate the nearest available ETOPS Alternate Airports within 240 minutes diversion time (at one-engine-inoperative cruise speed under standard conditions in still air).
What was the FAA 60 minute rule?
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.
What are etops requirements?
There is a set of standards that ETOPS certification requires both the aircraft and airline to comply with. For the aircraft, the manufacturer must demonstrate that flying with one engine is relatively manageable by the flight crew, safe for the airframe, and an extremely rare occurrence.
What is ETP aviation?
Definition. The Critical Point (CP), or Equal Time Point (ETP), is when an aircraft is the same flying time from 2 potential en-route diversions. Calculation of appropriate CPs aids decision making when deciding courses of action following a significant event such as an engine failure or on-board medical emergency.
What does etop stand for?
Environmental Threat and Opportunity Profile
ETOP stands for Environmental Threat and Opportunity Profile.
What’s the difference between ETOPS 180 and 207?
Basically, ETOPS 207 (180 min + 15 percent) is an operational extension of ETOPS 180 (before ETOPS 240 and 330 were certified) to be used in case a 180-min alternate airport was not available due to some reason. Note that 207-minute ETOPS is not subject to the new ETOPS requirements for “beyond-180-minute flight operations.”
Where can ETOPS be conducted beyond 240 minutes?
(1) The FAA grants approval to conduct ETOPS with diversion times beyond 240 minutes for operations between specified city pairs on routes in the following areas: (i) The Pacific oceanic areas between the U.S. west coast and Australia, New Zealand, and Polynesia; (iv) The oceanic areas between Australia and South America, and the South Polar Area.
What are the ETOPS requirements for an airplane?
The FAA grants approval to conduct ETOPS greater than 180 minutes. The following are requirements for all operations greater than 180 minutes. (1) The FAA grants approval only to certificate holders with existing 180-minute ETOPS operating authority for the airplane-engine combination to be operated.
How long can ETOPS be used in north polar area?
(1) The FAA grants approval to conduct 240-minute ETOPS authority with maximum diversion times in the North Polar Area, in the area north of the NOPAC area, and the Pacific Ocean area north of the equator as an extension to 180-minute ETOPS authority to be used on an exception basis.
