I'm sorry, but you just can't deny this fact.
Considering that it's not an actual fact
, I can very easily do so
An A340 even with it's weak little engines can stay up in the air with 1 engine operating
At empty weight+fuel and with 0% deration, it might... but not with anythign remotely resembling a payload typical of an intercontinental operation. A340s dont even have to be certified to take off nor fly at anything less than 75% power!
However when something does go wrong, you cannot deny the fact that having an extra 2 engines is better.
Perhaps you should research the proper diction of the word "fact"
From an mechanical perspective, your statement has somewhat of an arguementative value. From a non-operational point of view.... tell me this: in the event of a hijacking (a very REAL reality now), a fuel loss, an electrical failure, a medical emergency, the smell of smoke, etc; would you rather be within 2-3hr diversion distance, or have 2 engines for "safety"? Just wondering
ETOPs stand for Extended Twin Operations and determines how long a twin engine aircraft can fly over a body of water with 1 engine.
Completely inaccurate assessment: ETOPS as an acronym stands for "Extended-range Twin-engine Operational Performance Standards" and its criteria for certification is not related in any way whatsoever
to whether or not an aircraft is equipped to operate over water.
ETOPs has nothing to do with 4-engined aircraft with the exception of the Concorde
wrong again. ETOPS officially has nothing to do with Concorde, just that those aircrafts' operators have chosen to fly them to most of the standards dictated by ETOPS on scheduled routes.
