ETOPS Current Def in i t ionsFAA Definition : "Extended Range Operation with Two-engine
Airplanes (ETOPS)" and also referred to as Extended -range Twin-engine Operations (ETOPS)
Technical - AC120-42A: "For the purpose of this AC, extended
range operations are those flights conducted over a route thatcontain a point further than one hour flying time at the approved one-engine inoperative cruise speed (under standard conditions in stillair) from an adequate airport."
ETOPS Portion of Flight - That portion of a flight that begins thefirst moment an aircraft is greater than one hour flying time at theapproved single-engine inoperative cruise speed (under standardconditions in still air) from the nearest adequate airport, and ends thelast moment it is greater than one hour from the nearest adequateairport.

Preclude ETOPS design enhancements have increased therobustness of airplane systems and driven further gains in the extremereliability of modern fanjet engines. ETOPS maintenance requirementsalso reduce diversions through engine condition and oil
level/consumption monitoring, the aggressive resolution of reliabilityissues, and procedures to avoid human error during maintenance ofairplane engines and systems.
Protect ETOPS protects diverting jetliners through safety-enhancingoperational requirements such as dispatch, communications, alternateairport weather, fuel.

Exten ded Operat ion s New Defini t io n
Reflecting the ARAC proposal that ETOPS requirements be appliedmore broadly to embrace all extended operations, regardless ofnumber of engines, the ARAC further proposes that the ETOPSacronym be redefined as extended operations. Shifts guidance
material to regulatory.
Under this revised definition, ETOPS flying would begin when theairplane is more than 60 minutes (for twinjets) or 180 minutes (forthree- and four-engine jets) flying time from an adequate airport atan approved one-engine-inoperative cruise speed under standardconditions in still air.

Current Term :Sui table En Rou te Al ternate This word currently has an ETOPS-applicablemeaning (if used with reference to an en route airport, it denotes that this airportis above the required weather minimums and thus available for use as anETOPS alternate). With the updating of ETOPS now proposed by the ARAC, as
described in this booklet, this ETOPS-specific meaning will go away and bereplaced by ETOPS Alternate (see below). Once this rule takes effect, wheneversuitable appears in the ETOPS regulations and associated guidance andadvisory material, therefore, it should be interpreted according to its broadlyaccepted everyday definition.
New Term :ETOPS A lternate An airport that meets stated requirements for planneddiversion use and at which the weather conditions are at or above operatingminimums specified for a safe landing. This new ETOPS-specific term replacessuitable (see immediately above).

All operators must have a sufficient set of en route alternate airports
Key Airport Provisions
Must be certificated under FAR Part 139, or meet equivalent criteriaif outside FAA jurisdiction
Must be suitable to safely operate the aircraft, i.e., runway ofsufficient length, width and strength (ref FAR Part 121)
Must have minimum of ARFF Index A (FAA) or Category 4 (ICAO)response capability within 30 minutes
Must have field reporting conditions (NOTAMS), Hourly weatherreporting (METARS) and an instrument approach other than GPS.
Airport must be available but does not need to be continuously open(plan in place to reopen key airport services in case of aircraftemergency)

For dispatch, the minimum rescue fire fighting capability requirements are asfollows: For ETOPS up to 180 minute diversion length, alternates must have rescuefire fighting capability equivalent to that specified by ICAO Category 4. For Two-Engine, 207 Minute operations, alternates must have rescue firefighting capability equivalent to that specified by ICAO Category 4. Inaddition, at least one adequate airport within the 207 minute diversion timemust have rescue fire fighting capability equivalent to that specified by ICAOCategory 7. For all other ETOPS operations beyond 180 minutes, alternates must haverescue fire fighting capability equivalent to that specified by ICAO Category 7.
If the necessary equipment and personnel are not immediately available atthe airport, a 30 minute response time is deemed adequate if the initialnotification to respond can be initiated while the diverting aircraft is en route.Such equipment must be available on arrival of the diverting airplane andshould remain as long as their services are needed.

Typical Policy Statement for Remote US Military Airports :
"The US Navy advises that NSF Diego Garcia may be identifiedas an Extended Range Twin Engine Operations (ETOPS)emergency landing site (en route alternate) for flight planningpurposes. This is consistent with US government policy that anaircraft can land at any US military airfield if the pilot determinesthere is an in-flight emergency that would make continued flight
unsafe. However, as NSF Diego Garcia is a military facility, it isincumbent on aircraft operators to continuously monitor NOTAMSwhich may temporarily restrict the use of the airfield, even foremergency diversions. It is imperative that aircraft diverting toNSF Diego Garcia comply fully with all air defense procedures, asnon-compliance could be misconstrued as a hostile act.
Further, it is understood there are published criteria for ETOPSairfields, and our policy concerning emergency use is notagreement or certification that this airfield meets those criteria.NSF Diego Garcia is a remote location with resources(accommodations, medical, hangars, crash/fire/rescue, etc)limited to levels essential for support of assigned personnel andthe military mission. The airfield is available "as is" for emergencyuse only as indicated above."

All operators value the availability of en routediversion airports.
Airlines typically include diversion planningbecause it enhances safety.
