Sorry for my ignorance (I'm usually a pretty smart guy  Wink ) but what exactly is ETOPS? Everybody keeps refering to the ETOPS 757, and I understand that it has something to do with twin engines (and I assume something about overseas) but somebody please fill in the blanks....

Thanks in advance!

Try searching for ETOPS or Extended Twin Engine OPerationS.

Basically, it's a program or certification which the aircraft and the operator must conform to in order to operate a twin engine aircraft over 60 minutes (on one engine) from a suitable airport.

but what exactly is ETOPS?

Here is some information that, hopefully, will clarify this topic a little. Hope it helps:

Also, there are different levels of ETOPS - certification has been extended to 120 and 180 minutes.

I believe it was TWA that pioneered ETOPS with 767's translatlantic - am I correct?

I read in a company memo a few months ago that Boeing is working with the FAA and the JAA to implement a "LROPS" program. (Long Range Operations.) This new program would supersede ETOPS. I don't know all the specifics but I know that it would eliminate the 60, 120, and the 180 minute rule for twin engine aircraft. I don't know when it will be certified or if ever.


Is it broke...? Yeah I'll fix it.

ETOPS now stands for Extended Operation

AFAIK, this isn't what LROPS is about. ETOPS will still apply to twins. LROPS covers more engined aircraft. Under ETOPS regulations, there are requirements for fire suppression equipment and other things that just make sense for long haul travel in general. They are not a requirement for more engined aircraft so LROPS will make them that. Basically, LROPS takes the parts of ETOPS that aren't specifically related to the powerplants and applies them to other aircraft.

It actually stands for "Extended-range Twin-Engine Operation Performance Standards".

This should cover it: http://en.wikipedia.org/wiki/ETOPS

He was talking about this, most likely:

DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Parts 1, 21, 25, 33, 121, 135
[Docket No. FAA-2002-6717; Notice No. 03-11]
RIN 2120-AI03

Extended Operations (ETOPS) of Multi-engine Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to issue regulations governing the design,
maintenance, and operation of airplanes and engines for flights that go
beyond certain distances from an adequate airport. This proposal would
extend some requirements that previously applied only to two-engine
airplanes to airplanes with more than two-engines. The proposed rule
implements existing policy, industry best practices and
recommendations, and international standards to ensure that long-range
flights will operate safely.

I see your point. But it's somewhat ambiguous if they are rewriting the meaning of the acronym or not.

If you did not get it till now, search for ETOPS and you will find many older threads about it.

True.

I also doubt they would rewrite the meaning of the acronym letter for letter, however if ETOPS is in fact expanded as indicated above, the meaning of the original acronym becomes less important than the current version (and applicability) of the standards.

I guess we will have to answer this question in two parts: the acronym means XXX, however the rules apply to all multi-engine planes since YYY.
