« Wave off ! » Le cri de l'officier résonne sur le pont d'envol pour signifier à tout le monde de... « dégager ». Bienvenue à bord du « Charles-de-Gaulle », le seul porte-avions de la marine française, qui vient de subir un lifting intégral d'une durée de deux ans, pour un coût total de 1,3Mds €.
Avant de repartir en mission dans quelques mois, ce mastodonte de 42 000 t pour 261 m de long poursuit ses entraînements au large de Toulon, son port d'attache. « On était orphelins, le Charles-de-Gaulle nous a manqué », sourit Christophe, capitaine de frégate et chef des pilotes.
Avec ses collègues, ils ont eu beau s'être entraînés sur piste classique et sur un porte-avions américain le temps de la rénovation, rien ne vaut à leurs yeux le prestige du bateau français, en service depuis 2001. Le « Charles-de-Gaulle » aura un successeur, a assuré Emmanuel Macron, lorsqu'il sera mis hors service vers 2040. Coût estimé : minimum 3 Mds€. Et durée de la construction : 15 ans... au moins !
Alors, en attendant, la France compte sur son unique porte-avions, véritable village flottant de 2000 habitants - un équipage de 17 à 55 ans, dont 140 officiers de pont, 300 techniciens, 33 cuisiniers, 2 boulangers, 17 % de femmes au total. Après 18 mois passés à la cale, il faut le remettre en service. D'où, en cette fin d'automne, un entraînement intensif en Méditerranée, à quelques dizaines de kilomètres des côtes françaises. Entre quatre et vingt Rafales (NDLR : avions de combat) sont catapultés trois fois par jour, décollant sur une piste d'à peine quelques dizaines de mètres.
Au signal des « chiens jaunes », ces officiers de pont reconnaissables à leur gilet coloré, les avions atteignent en quelques secondes les 200 km/h. Ce lundi-là, une poignée de jeunes pilotes - entre 22 et 26 ans - effectuent leur baptême de vol sur le « Charles-de-Gaulle ». Pour pouvoir manœuvrer sur un porte-avions, il leur faut avoir un minimum de 100 heures de vol sur Rafale. « On porte une attention toute particulière à ces jeunes », glisse, l'œil rivé à la piste, Jean-Philippe, chef des « chiens jaunes ».
À l'issue de leur vol - ce jour-là dans un ciel dégagé -, ces pilotes doivent accrocher l'un des trois brins d'arrêt situés sur la piste pour apponter. Ces épais c'bles qui stoppent le Rafale d'un coup sont indispensables sur une piste aussi courte. « C'est comme si on pilait sur autoroute », glisse un officier, qui scrute à l'horizon les premiers avions sur le retour. Paradoxalement, au moment de toucher le pont à 250 km/h, les pilotes doivent remettre les gaz à fond. Car, s'ils ratent les brins, il faut pouvoir redécoller à temps ! « On appelle ça un bolter, c'est un peu un bizutage pour les nouveaux », sourit l'expérimenté capitaine Christophe, 2000 heures de vol sur Rafale derrière lui.

Canada's Bombardier on Thursday reported a quarterly profit that beat expectations, boosted by demand for flying and maintaining private jets, but its free cash flow missed estimates, and its shares closed down 8.49%.

Remzi Seker May 22, 2020 With the expansion across the aviation industry of connectivity and computing services, cybersecurity has become ever more important. Connecting people, processes and assets creates new vulnerabilities and multiple attack points—from flight-critical avionics to passenger inflight entertainment networks and airline backend operations. Information about systems, protocols and technologies such as software-defined radio are now readily available well beyond the industry. Demand for greater efficiency meanwhile continues to increase connectivity and accelerate computerization within aviation infrastructure, including aircraft. Fortunately, ongoing efforts to protect aircraft, airlines and passengers from cybersecurity threats have been largely unaffected by the global pandemic, suggesting an opportunity for the industry to ramp up cybersafety programs and training amid the current slowdown. The comprehensive, coordinated nature of aviation cybersecurity initiatives means committees have long carried out their work primarily through virtual meetings, so those efforts are able to continue in full swing. With slowdowns taking place in other areas, the industry can address cybersafety at a more rapid pace. The aviation industry and its stakeholders have been working hard to tackle cybersecurity challenges comprehensively—from the supply chain and the maintenance of aircraft to operations. Such efforts remain essential so that cyberthreats affecting safety can be mitigated before they materialize, whether that happens during flight through physical access to a bus, by interfering with equipment through Wi-Fi or remotely disrupting operations. The need to weigh cyberthreats according to their safety impact, a practice referred to as “cybersafety,” requires a different perspective than that of IT cybersecurity. Cybersafety differs from traditional IT cybersecurity because of the need for safety certification, which relies on guaranteeing a system's behavior, or “determinism.” This unique characteristic of aviation cybersafety means that solutions widely used across traditional computing systems may pose serious certification challenges. Imagine rolling out security patches for every avionics component on a commercial aircraft. Tackling cybersafety challenges requires a coordinated, comprehensive, global effort. Multiple agencies are cooperating to establish much-needed standards. For example, the U.S. FAA and the European Union Aviation Safety Agency have been working with the RTCA and the European Organization for Civil Aviation Equipment to set harmonized cybersecurity standards. Efforts to secure the aviation ecosystem also include dedicated committees such as the FAA's Aviation Rulemaking Advisory Committee Aircraft System Information Security/Protection working group. Similarly, the Aerospace Industries Association has established the Civil Aviation Cybersecurity Subcommittee. In the U.S., the Aviation Cyber Initiative (ACI) is led by the Defense Department, Department of Homeland Security and FAA. The ACI includes experts representing government, defense, industry and academia who collaborate to tackle aviation cybersecurity threats. The Aviation Information Sharing and Analysis Center shares global threat intelligence among aviation companies. Globally, the International Civil Aviation Organization (ICAO) leads this work. Its Trust Framework Study Group (TFSG) includes experts from the FAA, EASA, commercial industry and academia and has established three important working groups. Academic institutions play a critical role in advancing cybersecurity research and training, too. Embry-Riddle Aeronautical University, for example, develops engineering solutions and provides degree, certification and training programs in aviation cybsersecurity. Faculty researchers contribute expertise to cyberdefense and preparedness efforts by serving on national and international committees and working groups and by organizing the annual Aero-Cybersecurity Symposium. Aviation's impeccable safety culture positions it well to combat and defeat cybersafety risks. In the years ahead, the industry will need to invest in expanded education and training as well as research to secure high-assurance systems that can be updated with minimal impact on certification. Computerization and Cyberphysical Systems As computing becomes ever more affordable, functions that were traditionally implemented through hardware are now being realized through software, and inclusion of software has supported increased customization. Cyberphysical systems are designed to perform a set of functions with limited impact on the physical environment, such as temperature control, welding and parts assembly. One feature of cyberphysical systems is a failsafe property that involves shutting down—an approach that is clearly not desirable midflight. Connectivity Inexpensive and ubiquitously available computing, combined with advancements in networking, have accelerated the networking of devices. The Internet of Things concept does not require any form of certification or service-quality assurance, let alone any safety requirement or oversight. Rather than leveraging the Internet of Things, the aviation industry might consider using “networked wings” to underscore its safety commitment.
