Safran's Philippe Petitcolin. Safran Is Easily Europe Rsquo
50SKYSHADESImage not found or type unknown- aviation news SAFRAN'S PHILIPPE PETITCOLIN News / Personalities Image not found or type unknown © 2015-2021 50SKYSHADES.COM — Reproduction, copying, or redistribution for commercial purposes is prohibited. 1 Safran is easily Europe’s most diversified aerospace company, with a range of businesses covering airliner, helicopter and space rocket engines to security detection systems, and landing gear to unmanned air vehicles. However a year into the top job, chief executive Philippe Petitcolin is keen to slim down the partially state-owned group’s sprawling portfolio, divesting non-core subsidiaries in security, and using the proceeds – as well as revenues from Safran’s stake in the booming CFM International – to invest in enterprises in aerospace equipment that “fit our DNA”. At the same time – a decade after Safran came into existence with the merger of French household names Snecma and Sagem – he wants to create a group identity by rebranding its many operating companies. This will see some of the biggest names in aerospace, such as Snecma, Turbomeca, Labinal and Messier-Bugatti-Dowty, begin to disappear later this year. “We are 10 years old as a company and it is time to act and think as one Safran,” says Petitcolin, a 28- year veteran of the group, who previously ran engine maker Snecma and wiring specialist Labinal. Relentless demand for commercial aircraft means Safran’s aerospace propulsion business continues to dominate its revenues. Safran and General Electric each own 50% of 40-year-old joint venture CFM International, whose CFM56 has a roughly three-quarter share of the narrowbody market, powering Boeing 737s and its 737 Max successor, and about half of all Airbus A320 and A320neo family jets. -
Day 2 May 20, 2009
Special RAA 2009 RAA Annual Convention, Salt Lake City, Utah Convention News May 20, 2009 Issue 35 WEDNESDAY Available on the RAA website raa.org Recognizing the importance of addressing the media scrutiny following last week’s three-day NTSB hearing, the RAA Board of Directors and Presidents’ Council met nearly non-stop yesterday, in an unprecedented move. Virtually all of the 32 member airlines, plus Delta and US Airways mainline executives, were represented. All of them committed, under the RAA umbrella, to dedicate whatever resources are necessary to learn not only from the recent accident but also from the two-and-a-half years of a perfect safety record. The nation’s news media were welcomed to attend this week’s Annual Convention and view directly the industry’s singular focus on safety. RAA President Roger Cohen notes, “We’re taking this opportunity to showcase what we’ve done every year for nearly 40 years of collaborative work with the FAA, our airlines and industry partners to share the absolute best safety practices.” In the closed-door Presidents’ Council and Board of Directors meetings yesterday, discussion centered on advancing the multi-layered safety programs such as FOQA, ASAP, SMS and LOSA. The presidents also heard from John Nance (see related story below), Assistant DOT Secretary Christa Fornarotto and key staffers from Congress. Airline CEOs had a private Exhibit Hall walk-thru yesterday afternoon prior to the official ribbon-cutting ceremony (see picture below). Praising the regional airline industry for its “mammoth achievement of professionalism and safety levels equal to main- stream airlines…and probably higher,” John Nance, an internationally recognized air safety analyst and advocate, cautioned regional airline executives to withstand the media scrutiny after the Colgan Air accident and “celebrate that you have accomplished a tremendous effort.” Now completing more than 50% of all the nation’s flights, regionals are the backbone of the air transportation system. -

European Aviation Safety Agency Notice of Proposed Amendment 2016-20 Appendix I — Aircraft type ratings for Part-66 aircraft maintenance licence RMT.0541 EXECUTIVE SUMMARY This Notice of Proposed Amendment (NPA) addresses a regulatory coordination issue related to the aircraft type ratings. According to the AMC to Part-66, type ratings should be endorsed on an aircraft maintenance licence (AML) in accordance with Appendix I to AMC to Part-66 ‘List of type ratings’. An NPA is issued regularly to amend this list with changes coming from industry and to add new aircraft types or to remove aircraft types whose the TC has been revoked or surrended. The main objective is to ensure a common standard throughout the Member States.

Juli 2009 2 Hochschule für Angewandte Wissenschaften Hamburg Fakultät Technik und Informatik Department Fahrzeugtechnik + Flugzeugbau Berliner Tor 9 20099 Hamburg in Zusammenarbeit mit: Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR) Institut für Lufttransportkonzepte & Technologiebewertung Blohmstraße 18 21079 Hamburg Verfasser: Arno Apffelstaedt Abgabedatum: 08.07.2009 1. Prüfer: Prof. Dr. Dieter Scholz, MSME 2. Prüfer: Dr.-Ing. Eike Stumpf Industrielle Betreuung: Dr.-Ing. Eike Stumpf 3 Abstract The strong growth in worldwide air traffic has raised concern on aviation’s impact on climate change. According to latest scientific estimates, carbon dioxide is one of the main contributors of aviation to global warming, accounting for up to the half of its entire positive radiative forcing. As a reaction to these findings, there is an increased interest among the industry, scientific community and governments in possible approaches to mitigating the carbon footprint of aviation. Aircraft CO2 emission is set by six technological key parameters, which define the range, the engine’s efficiency, the aircraft’s efficiency in terms of aerodynamics and weight, and the fuel efficiency in terms of heat content and fuel-specific CO2 emission. A parametric study on the single influence of the parameters is conducted, which gives engine efficiency, fuel heat content and the zero-lift drag coefficient as the most powerful technological levers. Future aircraft technologies are identified through a literature study. Some of the most promising concepts for a medium-term application are found to be laminar flow technologies, geared and open rotor engine architectures, new materials for primary structures and bio-fuels. -
