What's ETOPS?

Recommended Posts

I was reading a magazine today saying that Varig still uses their MD-11s in international flights over 11 hours because since they are trijets they don't don't have ETOPS problems.I remember reading once that 767-300s were ETOPS compatible...What the heck is ETOPS???????????Cheers!

Midway over the Atlantic in an ETOPs aircraft....Pilot comes on the mike and says:"ladies and gentlemen, do not be alarmed but you will notice the airplane is slightly banked. This is due to the loss of power from engine #1. You can be assured that this aircraft is capable of reaching our destination, however we will be traveling at a much slower speed and we will be late arriving at our gate."One passenger says to another, "hope we don't lose the other engine too, then we'll be up here for EVER"

Hi:The MD-11 that Varig is flying will be phased out in favor of the Boeing 777. Charles

Well just to clear something out.... due to the dramatic financial situation lived by Varig their 777 program is on hold. Fortunatelly we'll keep seeing those beautiful blue trijets for a bit longer in the sky :)Man you gotta love MD-11s in the Varig paintscheme....

How true, Engines Turn or People Swim.120 ETOPS for example means, if one of your engine fails, the other engine can take you to an alternate, certified to fly for 120 minutes on single engine.

Yeah, at Heathrow I rarely see an MD11 now - 777's most days .

Hi Gustavo,ETOPS is being able to reliably fly a twin engined aircraft beyond normal range minimums. Without ETOPS, there is a maximum distance you can be from an airport- it's measured in time (minutes) to get to an airport on only one engine. ETOPS just extends that time- so a 180 min ETOPS allows for a 3 hour flight on one engine.To qualify, you have to instigate special maintenance procedures. For instance, each of the 2 engines might be serviced at a different maintenance base, maybe even manufactored at a different plant- so there are "A" and "B" type engines. Both cannot be serviced or replaced together either. These controls limit the possibility of both engines failing at once.The ETOPS thought does have a fatal flaw though: With 3 or more engines, there are no restictions on engines to the degree that ETOPS requires. Many years ago now, an L-1011 (3 engines) had all 3 engines fail- the oil seals on all 3 were installed incorrectly after maintenance, luckily they made it back. ETOPS tries to prvent this- but the lack of such controls in this L-1011 instance could have been fatal.Bruce.
