A flight up to 4 hours ( over the sea ) in a turboprop will be possible now, after EASA granted certification of ETOPS 120 for the ATR 42 / 72 600 Series...

What an experience  ....I had my good dose of turboprops, and I loved every minute.... but 4 hours looking to the blue ocean....

We already have more than 4 hours of looking at the beautiful blue ocean with jets... 


I just wonder if there would ever be a 320-sized turboprop. In Germany, long-distance buses are taking up market share from the railway - could something like this ever happen in aviation? A market for people who rather care about money, but do not care if the airspeed is 0.85 Mach or 0.5 Mach?

How is a flight of up to four hours over the sea possible with the granting of a two hour ETOPS certification?

ETOPS120 simply means that they need to be up to 120 minutes flying time away from a suitable landing field.

So, with ETOPS120, you can fly from Glasgow to Reykjavik a 5 hours flight for a turboprop because of the Faroe Islands in between.

People have been doing overwater flights in turboprops for years, some P3 Orion crews have had the pleasure of 15+ hour sorties over water, to extend the endurance they shut one or two engine down.

Contrary to popular belief, ETOPS do not only refer to flights over the oceans but also to operations over some deserts without suitable airports, such as Siberia.

Now, Air Tahiti has achieved yet another milestone for ATR, becoming the first airline in the world to order both versions of the new ATR “series 600” family of turboprop airliners, with orders for two 70-seat ATR 72-600s and three 48-seat ATR 42-600s.

The longest scheduled route flown by any ATR airliner is 1,650 kilometres, a journey which typically takes 3 hours 40 minutes to complete. Again the operator is Air Tahiti, and again with an ATR 72-500, this time between Papeete and remote Gambier Island. That’s roughly the same distance as Sydney – Auckland or Paris – Stockholm.

No way. A scheduled four hour flight is scheduled with BOTH engines operating. If one engine fails at exactly the two hour point, the plane is going to fly SLOWER with the one remaining engine. It will take longer than two hours to get to either airport, which is outside the ETOPS 120 limit.

I don't have any performance data in front of me but I think you would be looking at a flight scheduled no more than 3:20 to satisfy the ETOPS 120 requirement.

A flight might also be scheduled without needing ETOPS, until the diversion airport has foul weather, and then ETOPS allows you to operate anyway.

Delivery of Air Tahiti's first ATR42-600 is expected I would suspect as the aircraft is already doing test flights:

The article specifically mentions areas like Polynesia or Siberia. A couple years ago the ATR was in Siberia for tests to extend its cold weather certification to -54 degrees. So perhaps they are indeed targeting customers in Siberian and similar remote regions.

It's a rough example for somone wondering how it would be a 4 hour flight as oppose to 2 when it's an ETOP 120....... to be exact though... your ETOPS range would actually be based of one engine inoperative speed, at ISA, in still air, plus required reserves (which can be reduced)

The reality is that there are a number of destinations where their airports have relatively short runways and/or in topography tight spots that a prop type a/c like the ATR is an ideal a/c vs. a non-prop jet a/c yet be large enough to carry a significant amount pax and cargo. With such situations low and slow but with high range and the ability to land/take off from short runways is desirable, including artic, dessert, over water areas. This could also save time and money for airlines with them from having to operate with a mandated intermediate stop due to low ETOPS.
With these ETOPS 120 ATR's, some operators will save money as well as pax and cargo will be better served.

Only one I can think of (if ever LI were to operate the route) is between CUR and SXM. I think that route is just outside the normal ETOPS 60 rule (for a t-prop of course).

Yes, of course. According to Wikipedia:

"The current production version is the −500 series. It is totally new generation aircraft with new engines, new propellers, improved hot and high performance, increased weight capacity and an improved passenger cabin. The 50-seat ATR 42–500 was first certificated in July 1995."

From http://www.AviationExplorer.com

"The new ATR 42–600 and ATR 72–600 will feature the latest technological enhancements while building upon the well-known advantages of the current aircraft, namely its high efficiency, proven dispatch reliability, low fuel burn and operating cost. It will include the new PW127M as standard engine (new engines provide 5% additional thermodynamic power at takeoff, thus improving performance on short runways, in hot weather and on high altitude; the incorporation of the “boost function” enables use of this additional power as needed, only when called for by the takeoff conditions), Glass Cockpit flight deck featuring five wide LCD screens that will replace the current EFIS (Electronic Flight Instrument System). In addition, a Multi-Purpose Computer (MPC) will further enhance flight safety and operational capabilities. The new avionics, to be supplied by Thales, will also provide CAT III and RNP capabilities. It will also include the new lighter and more comfortable seats and larger overhead baggage bins. The −600 series ATR aircraft will be progressively introduced during the second half of 2010. The ATR 42–600 Series launch customer is the Royal Air Maroc (deliveries begin in March 2012)."

I'm not convinced that the ATR really has any relations to an anti-submarine airframe.

If it is correct, then the only possible candidate is the Breguet Allantique.

But the Atlantique is a much bigger and heavier plane, and has more than twice as powerful RR Tyne engines. It also cruises much faster than the ATR at altitude. It first flew from Toulouse in October 1961, and as much upgraded version (Atlantique 2) it was produced for the French Marine until early 1990'es.

My wild guess would be that the ATR owes at lot more of its genes to the Nord 262.

The French Army and Marine used the Nord 262 for medevac and utility transport. Range is quoted as 650 miles, which hardly calls for ETOPS certification.

The Atlantique, however, is quoted with 5,000 miles range.

Longest flight (block time) that I've done in an ATR72 is just over 8 hours, and we still had nearly an hour's worth of fuel still in the tanks. I've also heard anecdotal evidence of 9+ hour flights in an ATR42.
