Bonjour à tous
Pour commencer un fil sur cet avion atypique, dont la configuration pourrait devenir courante avec les open rotors, voici un long compte rendu d'exploitation de cet avion en version II aux US

C'est assez long
Je vous avais déjà dit que j'aimais les hélices ?
Juste quelques extraits

T here are more than 100 Piaggio P180 Avanti II aircraft in service and they’ve logged more than 200,000 flight hours by some estimates, as of late August 2010. That’s an impressive number for less than five years of production, considering that only 105 of the original P180 aircraft were built between 1990 and 2005.
Perhaps that popularity is a result of Piaggio Aero Industries delivering on the promises it made for the Avanti II in late 2004, according to operators contacted for this report. The distinctive twin pusher turboprop has a 400 KTAS top cruise speed, Rockwell Collins Pro Line 21 avionics, considerably improved tanks-full payload and upgraded passenger amenities.
Piaggio predicted that the Avanti II would be 12-kt. faster in high cruise altitudes than the original P180, an aircraft that already held bragging rights as the “World’s Fastest Production Civil Turboprop.” Flight tests, though, revealed that the Avanti II was up to 20 kt. faster, primarily due to better-than-promised power output from its Pratt & Whitney Canada PT6A-66B engines. Maxed out at 400 KTAS, the Avanti II is almost 3% faster than the first-generation aircraft while fuel flows are about half that increase. The second-generation aircraft also is slightly more fuel efficient than the original model because it can climb to higher cruise altitudes.
The Avanti II has given up nothing regarding cabin roominess and low sound levels. The 9.0 pressurization system assures that cabin altitude never exceeds 6,600 ft., even at FL 410. The aircraft’s new interior design features LED interior lighting, a choice of three seating layouts and a roomier full-width aft lavatory.
Even more so than the original P180, the $7.195 million Avanti II blurs the distinction between turboprop and turbofan business aircraft. It can fly a 600-nm trip in 1 hr., 44 min. That block time splits the difference between the 600-nm flight times of most popular turboprop and typical midsize jets. The Avanti II’s midsize cabin cross-section is essentially the same size as a midsize jet’s and the cabin is much larger than that of any production business turboprop. The interior is far quieter than that of any other turboprop, and almost as quiet as some light and medium-size jets.
Its 70.3 lb/sq. ft. wing loading, 50 to 100% higher than conventional turboprops, actually approaches that of many midsize jets. This provides a jet-like ride in turbulence. In addition, the Avanti II can cruise in the mid-thirties, or higher, flight levels at which the air typically is smoother than at the lower altitudes used by most turboprops.
The Avanti II truly is a talented performer that delivers exceptional speed, fuel efficiency and comfort, according to operators.
But some also say it is somewhat of a prima donna, a star that requires more care and maintenance than conventional models in return. Viewpoints vary widely, as we discovered when we interviewed several operators.
