Here is a no music pure audio version of our last snow storm flight.
If you have any questions about to the aircraft feel free to ask.
Heres some specs on it.
The Piaggio P.180 Avanti is an Italian executive transport aircraft with twin turboprop engines mounted in pusher configuration. It seats up to nine people in a pressurized cabin and may be flown by one or two pilots. The design is of three-surface configuration, having both a small forward wing and a conventional tailplane, as well as its main wing, with the main wing spars passing behind the passenger cabin area.
The Avanti's counter-rotating turboprop engines are placed on a mid-set, high-aspect-ratio wing located just behind the cabin. The three-surface design incorporates both a T-tail and a pair of small, fixed forewings having slight anhedral and landing flaps. On the Avanti II these flaps automatically deploy in concert with the main wing flaps. This reduces the load on the tailplane, even when the flaps are deployed, by reducing the pitch-down moment created by the deployment of the main wing flaps.
The Avanti's forward wing flaps deploy automatically with the main wing flaps to maintain neutral pitch trim.
The forward wing's angle of incidence is slightly greater than that of the main wing, so that it stalls before the main wing, producing an automatic nose-down effect prior to the onset of main-wing stall; its five-degree anhedral (negative dihedral) keeps the stream wash interference clear of the engine inlets, the main wing and the tailplane.
Showing the continuously varying curve of the fuselage cross-section and forward wing
The cabin cross-section varies continuously along the length of the aircraft; the shape approximates an NACA airfoil section, and the slowly changing curve helps prolong laminar flow on the front of the fuselage. Piaggio claims that the fuselage contributes up to 20% of the Avanti's total lift, with the front and rear wing providing the remaining 80%. Due to the unusual fuselage shape, the mid-cabin is considerably wider than the cockpit. The front and rear airfoils are custom sections designed by Jerry Gregorek[39] of Ohio State University's Aeronautical and Astronautical Research Laboratory to achieve a drag-reducing 50% laminar flow at cruise.
Cabin
The P180 is reported to have good fuel efficiency relative to small turbojets flying in the same speed and altitude range. Flight International stated: "The Avanti has no direct turboprop competitors, its closest jet rivals are the Raytheon Premier I and the Cessna Citation CJ2+ ... Piaggio says low-drag laminar flow is maintained to around 50% of the wing chord, compared with around 20–25% for conventional tractor turboprops where propeller wash disturbs the airflow over the wing. By this estimate, mileage is 70% better per fuel unit than comparable jet aircraft, although this greater efficiency is achieved only at a relatively slow 315 KTAS and FL410.[42] P180 Avanti II Specifications now show slightly lower numbers for specific range of 3.1 km/kg.
Interior noise is lower than in conventional turboprop aircraft, because the propellers and engine exhausts are behind the cabin. Piaggio quotes 68 dBA. However, due to the strongly disturbed flow in which the pusher propellers operate, the exterior noise is higher. The exterior noise level and its higher pitched sound has been shown to be the result primarily of the interaction of the turbine engine exhaust flows and the five-bladed pusher propellers (est. +9 dB).[43] On takeoff, the Avanti has been measured at 81.9 dBA sideline noise level, slightly lower than the Beechcraft King Air at 82.8 dBA. This is below FAA stage-3 noise limits, which set a maximum of 89 EPNdB for takeoff.
The Piaggio P.180 Avanti has a sea-level standard-day maximum-gross-weight takeoff distance of 869 m (2,851 ft) and a landing roll of 872 m (2,861 ft).[49]
In 2014 Piaggio announced development of an updated version, named EVO. It uses new Hartzell composite propellers, with blades of scimitar configuration. Its wings carry new winglets; aerodynamic improvements have been incorporated, and an additional 60-gallon (400 lb) fuel tank option to increase range to 1,770 nautical miles (3,280 kilometres; 2,040 miles).[51][52] The company predicts improved climb performance, 250 nmi greater range, and 3% reduction in fuel usage. The revised propeller shape, combined with a lower engine speed, promises a 68% reduction in external noise. Avanti EVO type certification was granted by EASA on 28 November 2014,[53] and by the FAA on 6 July 2015.[54] Projected purchase price was $7.4 million in 2014.[55] By 2021 the equipped price was $7.695 million.[56] The first EVO was delivered in April 2015, with five more to follow the same year.
