on SAF would be supplemented by a mild hybridation during the take-off and climb phases for a 20% lower fuel burn. Other improvements could include an eight-bladed propeller, thermal de-icing to replace the current pneumatic boots, a single lever FADEC for both engine and propeller and an aerodynamic clean-up of the secondary structures like the nacelle-wing junction. A cabin revamp would save weight with recycled carbonfibre or bio-sourced resin and natural fibres. On September 17, 2022, Stefano Bortoli was succeeded as CEO of ATR by Nathalie Tarnaud Laude, former president of NHIndustries and Senior Vice President Head of the NH90 Programme for Airbus Helicopters.On 21 June 2022, ATR completed its first flight 100% SAF-powered regional aircraft. Products Proposed aircraft ATR 52C The ATR 52C was a military variant of the ATR 72-100 that included a rear ramp-type cargo door and strengthened cabin floor. ATR 82 Beginning in the mid-1980s, the company investigated a 86-seat derivative of the ATR 72. The ATR 82 would have been powered by turboprops, after an airline survey concluded that the market preferred turboprops instead of turbofans for aircraft that seated fewer than 90 passengers. The powerplants would have been chosen from the Allison AE2100G, Textron Lycoming LP512, or the General Electric GLC38. The aircraft would have a cruising speed as high as . The ATR-82 project (as it was dubbed) was suspended when Aero International (Regional) () was formed in early 1996. ATR 92 The company proposed a five-to-six abreast, 95–105 seat airliner at the 1988 Farnborough Air Show. The aircraft would have cruised at , and it would have been powered by a turbofan, high-speed turboprop, or an unducted fan. ATR stretch In 2007, as a response to the Q400X proposal, ATR floated the idea of a 90–99 seater stretch. As of 2009, it was considered part of the future -900 series ATR family. In 2011, the 90-seater was proposed to shareholders. As of 2012, a new clean-sheet design was considered in the 90-seat segment, for a 2017 launch. As of 2017, development of a 90-seater for an expected demand of 2,000–2,500 units over 20 years was expected to cost more than $5bn. Fuel burn would need to be reduced by at least 30%, and the unit price would need to stay in the low-to-mid-$20m range, below small jets. Leonardo S.p.A. preferred a clean-sheet 90-100 seater with new turboprops, wings and cockpit available soon
