The certificate holder must have been operating at minute or greater ETOPS authority for at least 24 consecutive months, of which at least 12 consecutive months must be at minute ETOPS authority with the airplane-engine combination in the application.
There were routes traversing the Southern hemisphere, e. Before the introduction of the Airbus AXWB inregulations in North America and Europe permitted up to minute ETOPS at entry.
The A XWB was first to receive an ETOPS prior to entry into service by European authorities, [13] enabling economical nonstop routes between Europe and Oceania and thereby bypassing historical stopovers across Asia and North America by the late s and early s.
This includes the high-demand London—Sydney routein the latest development for ultra long-haul flights. The A XWB's current ETOPS certification covers Meanwhile, the first time that ETOPS approval was given to a four-engine aircraft was in Februaryto the Boeing Intercontinental.
The North Atlantic Tracks are the most heavily used oceanic routes in the world, and are largely covered by ETOPS minute rules, thereby removing the necessity of using minute rules.
However, North Atlantic diversion airports are subject to adverse weather conditions that affect their availability for use. By the mids, virtually all North Atlantic plane routes were dominated by twin-engine aircraft.
During the Cold Warroutes between Europe and East Asia were prohibited from flying over Soviet Union or China since both airspaces were previously heavily military-controlled. Virtually all flights between Europe and North East Asia flew over the U. They flew near the North Pole with a very large distance to usable airports, for which only three- and four-engine wide-body aircraft were permitted for safety reasons by international aviation authorities.
Some flights between Europe and Oceania still largely pass through stopovers in Asia either in the Middle East or Southeast Asia or North America either in Canada or the U. given the current aircraft range restrictions and, in the case of the early s, the reinstatement of selected routes by airlines between the Western Hemisphere and Eastern Hemisphere bypassing Russia due to its ongoing war with Ukraine.
For decades, narrow-body aircraft like the Airbus A series, and the Boeing series and have continuously operated flights as approved for ETOPS operation, alongside earlier wide-body aircraft such as the A and Aand Boeing The success of ETOPS aircraft like A and Boeing made the intercontinental trijets obsolete for passenger use, production of which was largely ended by the late s with Boeing cancelling the MD program in the same period.
The rules have also allowed American legacy carriers United Airlines and Delta Air Lines in particular to use the Boeing on "long and thin" transatlantic routes between their major hubs and secondary European cities [15] that cannot generate the passenger demand to justify the use of a widebody airliner.
The practice has been controversial, because although the has adequate range to cross the Atlantic Ocean comfortably, strong headwinds caused by the jetstream over the winter months can result in westbound flights being declared "minimum fuel", forcing a refuelling stop at Gander, Newfoundlandin order to safely complete their journey.
Aloha Airlines operated minute ETOPS—approved Boeing aircraft on nonstop routes between the Hawaiian Islands and the western U. and also Vancouver, Canada. The use of the smaller enabled Aloha to serve routes that could not support larger jet aircraft with an example being the Honolulu — Burbank nonstop route.
Prior to the operation, Aloha Airlines had operated aircraft to various Pacific islands utilizing minute ETOPS.
Other new-generation ETOPS aircraft include the Airbus A series, the Embraer E-Jets series and the ATR By the mids, the widespread successes of ETOPS-reliant narrow-body aircraft have diminished the global market share of double-deck wide-body jets.
At the onset of the COVID pandemic in the early s, Boeing and Airbus have since ended all production of the and Arespectively and both being the two largest commercial aircraft in the world. At the same time, the increasing prominence of new-generation ultra-long-range wide-body twinjets like the Boeing andand Airbus A and A over the last decade has shifted the favor from quadjets to twinjets for international long-haul travel.
The cornerstone of the ETOPS approach is the statistics showing that the turbine assembly of a modern jet engine is an inherently reliable component. Engine ancillaries, by contrast, have a lower reliability rating. Therefore, an ETOPS-certified engine may be built with duplicate sets of certain ancillaries in order to receive the required reliability rating.
ETOPS approval is a two-step process. First, the airframe and engine combination must satisfy the basic ETOPS requirements during its type certification.
This is called "ETOPS type approval". Such tests may include shutting down an engine and flying the remaining engine during the complete diversion time. Often such tests are performed in the middle of the ocean.
It must be demonstrated that, during the diversion flight, the flight crew is not unduly burdened by extra workload due to the lost engine and that the probability of the remaining engine failing is extremely remote. For example, if an aircraft is rated for ETOPS, it means that it is able to fly with full load and just one engine for three hours.
Second, an operator who conducts ETOPS flights must satisfy their own country's aviation regulators about their ability to conduct ETOPS flights. This is called "ETOPS operational certification" and involves compliance with additional special engineering and flight crew procedures in addition to the normal engineering and flight procedures.
Pilots and engineering staff must be qualified and trained for ETOPS. An airline with extensive experience operating long distance flights may be awarded ETOPS operational approval immediately, while others may need to demonstrate ability through a series of ETOPS proving flights.
Regulators closely watch the ETOPS performance of both type certificate holders and their affiliated airlines. Any technical incidents during an ETOPS flight must be recorded. From the data collected, the reliability of the particular airframe-engine combination is measured and statistics published.
The figures must be within limits of type certifications. Of course, the figures required for ETOPS will always be more stringent than ETOPS Unsatisfactory figures would lead to a downgrade or, worse, suspension of ETOPS capabilities either for the type certificate holder or the airline.
Engines must have an in-flight shutdown IFSD rate better than 1 per 20, hours for ETOPS, 1 per 50, hours for ETOPS, and 1 perhours for beyond ETOPS Private jets are exempted from ETOPS by the FAA, but are subject to the ETOPS minute rule in EASA's jurisdiction. Government-owned aircraft including military do not have to adhere to ETOPS regulations.
There are different levels of ETOPS certification, each allowing aircraft to fly on routes that are a certain amount of single-engine flying time away from the nearest suitable airport. For example, if an aircraft is certified for minutes, it is permitted to fly any route not more than minutes' single-engine flying time to the nearest suitable airport.
The following ratings are awarded under current regulations according to the capability of the airliner:. Until the mids, the term EROPS extended range operations was used before being superseded by ETOPS usage. Inwhen Boeing proposed to extend ETOPS authority for twins to beyond minutes, Airbus proposed to replace ETOPS by a newer system, referred to as Long Range Operational Performance Standards LROPSwhich would affect all civil airliners, not just those with a twin-engine configuration with more than minutes ETOPS.
The FAA stated in the Federal Register in This final rule applies to air carrier partcommuter, and on-demand part turbine powered multi-engine airplanes used in extended-range operations. However, all-cargo operations in airplanes with more than two engines of both part and part are exempted from the majority of this rule.
Today's rule [January 16, ] establishes regulations governing the design, operation and maintenance of certain airplanes operated on flights that fly long distances from an adequate airport.
This final rule codifies current FAA policy, industry best practices and recommendations, as well as international standards designed to ensure long-range flights will continue to operate safely. Several commenters … recommended use of the acronym "LROPS"—meaning 'Long Range Operations'—for three- and four-engine ETOPS, to avoid confusion, particularly for those operations beyond minutes' diversion time.
The FAA has decided to use the single term, 'extended operations,' or ETOPS, for all affected operations regardless of the number of engines on the airplane. Prior tothe FAA used the term for Extended Range Operation with Two-Engine Airplanes but the meaning was changed when regulations were broadened to include aircraft with more than two engines.
EDTO — Extended Diversion Time Operations. ICAO amendment 36 replaced the term ETOPS with the new term EDTO Extended Diversion Time Operations.

Usually, the contract an airline has with a station says something to the effect they they will be available if notified. As for being aware of hours, we have a lookup feature on our computers that state operational hours, customs, tower, and station manager along with phone numbers for each.
By late night, I meant to say that I will call them if I plan on using them for a late night flight. If I can't get a hold of anyone, I will use a different airport as an alternate. BobDDuck Island Bus Driver.
If we have a published alternate on our release, our dispatcher is supposed to notify the station and let them know the time window when they may get an inbound.
The station manager or who ever is on duty that day is supposed to be available to come in during that time frame if needed If we have something un planned happen, unless it's an absolute emergency, part of the decision making try is to go somewhere that can provide needed services and minimized international issues.
Obviously, if you are on fire, you go where you need to. MikeD Administrator Staff member. BobDDuck said:.

Click to expand knot4u Repeat Offender. We had a stair truck and a belt loader that would normally sit idle the majority of the time.
It was all hands on deck when the fog rolled in down south and suddenly we had 5 inbound s, trying find or make space to park them, getting the ground equipment up and running and coordinating with the airline and the buses they'd send to pick up their irate passengers we'd leave them on the plane until the buses showed up.
The worst ones were those flights with people coming back from Mexico, they'd just park and have to sit there, we had zero Customs support, I do recall fueling one because they were going to flameout their APU if they didn't get some fuel.
The FBO would call everyone that worked there and ask them to come in to help when these events happened, most would either say no or just not answer the phone this was before cell phones were popular.
I ended up getting locked in a baggage compartment one night by my coworkers because an off-shift supervisor came in at about 1am and the first thing he did was warm up and eat my carne asada burrito plate, I was going to kill him, I'd been working for 11 straight hours at that point.
He actually was asked to go home so I could be released, luckily the girls who worked the counter were "fond" of me and one went to Tommies for a couple of double chili cheeseburgers. I'd say making sure the place you divert to can actually handle the load you send is pretty important, an in person audit would be prudent.
All of those s were Delta by the way. Murdoughnut Well sized member. I was talking to an airport director just the other day about this. He had a potential situation where a plane was going to land for a medical, but the ground handlers were forbidden from touching the airplane different carrier.
The captain changed their mind while on approach and went to one of their stations instead. azmedic Well-Known Member. More often than not Airport Ops can at least get us a gate and then give us some contact numbers or some of us will reach out to colleagues that at are at other airlines to see if they can get us in touch with someone who can handle us Sent from my iPhone using Tapatalk Pro.
I can't imagine trying to get out the gate ladder at a terminal that isn't already in our system. As a dispatcher, this is not an uncommon situation. Late at night, there are not many stations that are willing to take diversions.
You cant always list a hub airport on the release and weather dictates where a diverted plane goes. Plane has to land somewhere. Theres always something that can be worked out to let passengers off the plane or get plane fueled for gas and go.
Its not ideal to divert to outstations late at night but when you need to divert and there arent many good options weather wise, passenger handling comes second to putting the plane safely on the ground.
Burrito You ARE Freaking out. Back at MHT, we used to have an agreement with B6 that sounded more and more like a "yes please" when BOS WX took a dive. It got creative during some summer thunderstorms, but it really didn't get beyond the phone call of a dispatcher asking for the trucks to be ready, apologizing to us afterwards.
We'd only ever have the hair raise up in the winter if deicing were involved, because the staffing was always so bad. No OT allowed. Figure it out. Thanks, bye.
The time BOS lost their fuel farm due to a pump fire, we had everything up to Delta s using us for tanker stops before continuing south. Again, non-normal stuff, and after 3 or 4 transcontinentals were cleared and stopping by, BOS APP just stopped using us altogether because the airport would've run out of fuel.
The real challenge was JFK, if a line of storms were preventing BOS and BDL for ALTNs. Only ever happened once that I recall, but like the guys above had said: Get it on the ground and figure it out later. In my particular recollection, Delta sent us a and we had to send it to the FedEx spot, but because no one had those towbars, they had to swing it perpendicular and the on-duty guy had to call desperately for help.
Something like that. Get it on the ground, really, was always the big takeaway for me. Looking at the KAL A post in another thread I'm glad no one was killed. Murdoughnut said:.

ETOPS and beyond are now permitted [9] on a case-by-case basis, with regulatory bodies in the United States, Australia, and New Zealand adopting said regulatory extension. Authority is only granted to operators of two-engine airplanes between specific city pairs.
The certificate holder must have been operating at minute or greater ETOPS authority for at least 24 consecutive months, of which at least 12 consecutive months must be at minute ETOPS authority with the airplane-engine combination in the application.
There were routes traversing the Southern hemisphere, e. Before the introduction of the Airbus AXWB in , regulations in North America and Europe permitted up to minute ETOPS at entry. The A XWB was first to receive an ETOPS prior to entry into service by European authorities, [13] enabling economical nonstop routes between Europe and Oceania and thereby bypassing historical stopovers across Asia and North America by the late s and early s.
This includes the high-demand London—Sydney route , in the latest development for ultra long-haul flights. The A XWB's current ETOPS certification covers Meanwhile, the first time that ETOPS approval was given to a four-engine aircraft was in February , to the Boeing Intercontinental.
The North Atlantic Tracks are the most heavily used oceanic routes in the world, and are largely covered by ETOPS minute rules, thereby removing the necessity of using minute rules. However, North Atlantic diversion airports are subject to adverse weather conditions that affect their availability for use.
By the mids, virtually all North Atlantic plane routes were dominated by twin-engine aircraft. During the Cold War , routes between Europe and East Asia were prohibited from flying over Soviet Union or China since both airspaces were previously heavily military-controlled.
Virtually all flights between Europe and North East Asia flew over the U. They flew near the North Pole with a very large distance to usable airports, for which only three- and four-engine wide-body aircraft were permitted for safety reasons by international aviation authorities.
Some flights between Europe and Oceania still largely pass through stopovers in Asia either in the Middle East or Southeast Asia or North America either in Canada or the U. given the current aircraft range restrictions and, in the case of the early s, the reinstatement of selected routes by airlines between the Western Hemisphere and Eastern Hemisphere bypassing Russia due to its ongoing war with Ukraine.
For decades, narrow-body aircraft like the Airbus A series, and the Boeing series and have continuously operated flights as approved for ETOPS operation, alongside earlier wide-body aircraft such as the A and A , and Boeing The success of ETOPS aircraft like A and Boeing made the intercontinental trijets obsolete for passenger use, production of which was largely ended by the late s with Boeing cancelling the MD program in the same period.
The rules have also allowed American legacy carriers United Airlines and Delta Air Lines in particular to use the Boeing on "long and thin" transatlantic routes between their major hubs and secondary European cities [15] that cannot generate the passenger demand to justify the use of a widebody airliner.
The practice has been controversial, because although the has adequate range to cross the Atlantic Ocean comfortably, strong headwinds caused by the jetstream over the winter months can result in westbound flights being declared "minimum fuel", forcing a refuelling stop at Gander, Newfoundland , in order to safely complete their journey.
Aloha Airlines operated minute ETOPS—approved Boeing aircraft on nonstop routes between the Hawaiian Islands and the western U. and also Vancouver, Canada. The use of the smaller enabled Aloha to serve routes that could not support larger jet aircraft with an example being the Honolulu — Burbank nonstop route.
Prior to the operation, Aloha Airlines had operated aircraft to various Pacific islands utilizing minute ETOPS. Other new-generation ETOPS aircraft include the Airbus A series, the Embraer E-Jets series and the ATR By the mids, the widespread successes of ETOPS-reliant narrow-body aircraft have diminished the global market share of double-deck wide-body jets.
At the onset of the COVID pandemic in the early s, Boeing and Airbus have since ended all production of the and A , respectively and both being the two largest commercial aircraft in the world. At the same time, the increasing prominence of new-generation ultra-long-range wide-body twinjets like the Boeing and , and Airbus A and A over the last decade has shifted the favor from quadjets to twinjets for international long-haul travel.
The cornerstone of the ETOPS approach is the statistics showing that the turbine assembly of a modern jet engine is an inherently reliable component. Engine ancillaries, by contrast, have a lower reliability rating.
Therefore, an ETOPS-certified engine may be built with duplicate sets of certain ancillaries in order to receive the required reliability rating. ETOPS approval is a two-step process. First, the airframe and engine combination must satisfy the basic ETOPS requirements during its type certification.
This is called "ETOPS type approval". Such tests may include shutting down an engine and flying the remaining engine during the complete diversion time. Often such tests are performed in the middle of the ocean. It must be demonstrated that, during the diversion flight, the flight crew is not unduly burdened by extra workload due to the lost engine and that the probability of the remaining engine failing is extremely remote.
For example, if an aircraft is rated for ETOPS, it means that it is able to fly with full load and just one engine for three hours. Second, an operator who conducts ETOPS flights must satisfy their own country's aviation regulators about their ability to conduct ETOPS flights.
This is called "ETOPS operational certification" and involves compliance with additional special engineering and flight crew procedures in addition to the normal engineering and flight procedures. Pilots and engineering staff must be qualified and trained for ETOPS. An airline with extensive experience operating long distance flights may be awarded ETOPS operational approval immediately, while others may need to demonstrate ability through a series of ETOPS proving flights.
Okay but what would you do if this situation arose? Pull the chute and evacuate or deal with it another way? And yet this airline did. Playing devils advocate here how would you have know the airport you were diverting to had a groundstop with full gates?
ATC inquirey or would you hope dispatch informed you about oh by the way you dont wanna land in vegas, theres a ground stop. I get that its there job but what I dont get is how did they let it get this far?
Im gessing someone from management made the call to send that ACARS popping the slides. It happened. Who cares. Old history. How about focusing on becoming a dispatcher first than trying to second guess an old event.
Sorry just can't belive this actually happened. I was surprised when I found out it happened for real. Well whats the point of blowing the slide then if you are not going to use it?
Was it just to say to the DOT umm stop the clock we gave the pax a way out only they had to go down a slide IF they wanted to exit the plane. LyteChop Well-Known Member. typhoonpilot Well-Known Member.
Dozens of DAL jets on the taxiway for 8 hours plus. We landed and went to our gate. Company de-ice on the gate; push and go; all inside an hour. Did someone say Tier 1? trafficinsight Well-Known Member. JordanD Honorary Member. trafficinsight said:. JordanD said:. Not to mention nobody on the internet knows the full story of what they tried to do or what went down.
Okay, so you land somewhere near the mountains which are rocky. It was 85 degrees yesterday and unexpectedly snowing heavily today, they don't have deice crews or enough tow teams to clear gates since flights are cancelling by the dozen. Wait for a gate is 3 hours and increasing.
Tell us your captain stuff, please. Sent from my XT using Tapatalk. Is it where I was supposed to land, or am I diverting into said airport? We landed at an airport that you had no idea we were going to, and no way to service the airplane. Figure it out!
