A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions.

Iverson](https://time.com/author/jeffrey-t-iverson/) Jun 5, 2009 4:00 AM UTC  An Airbus A330-200 An Airbus A330-200 Reuters/Air France by [Jeffrey T. Iverson](https://time.com/author/jeffrey-t-iverson/) Jun 5, 2009 4:00 AM UTC As the French team leading the investigation into the Air France Flight 447 crash works through the multitude of likely and less likely disaster scenarios — from the repercussions of stormy conditions to an act of terrorism — perhaps among the most difficult to assess will be possible flight computer malfunctions. Air France CEO Pierre-Henry Gourgeon noted on Monday that immediately preceding AF447’s disappearance, automatic messages sent by the plane indicated “multiple technical failures.” As details emerge regarding these messages, experts will struggle to understand whether they were the inevitable result of the plane’s breaking up or indicators of the failures that led to the accident. ([Read “What Brought Down Air France Flight 447?”](https://www.time.com/time/world/article/0,8599,1902151,00.html)) Gourgeon said the “succession of a dozen technical messages” sent by AF447 showed that “several electrical systems had broken down” immediately prior to the crash. A chronology of these messages acquired by the São Paolo daily _Jornal da Tarde_ show that moments before the plane is believed to have plunged into the ocean, its autopilot became disengaged and the plane sustained damage to its stabilizing controls and flight systems, as well as a failure of the systems that were monitoring the aircraft’s speed, altitude and direction: the ADIRU (Air Data Inertial Reference Units) and the ISIS (Integrated Standby Instruments System). These are key components in fly-by-wire systems, which use computers and wires instead of mechanics and hydraulics to control a plane’s flight. ([Watch TIME’s video of the rescue of US Airways flight 1549.](https://www.time.com/time/video/player/0,32068,8096727001%5F1872207,00.html)) On Wednesday, TIME revisited an October 2008 incident in which a Qantas Airbus 330 — the same model as AF447 — unexpectedly went into a brief yet harrowing 20-second nosedive, causing multiple injuries and requiring an emergency landing. [The investigation that followed](https://www.time.com/time/world/article/0,8599,1902421,00.html) blamed an ADIRU failure for the 330’s uncommanded dive: one of the plane’s three ADIRUs, which are designed to help the plane’s flight-control computer fly the plane safely, began sending erroneous data spikes to the flight-control computer. Instead of deferring to the information of the two functioning ADIRUs as it normally should, the computer acted on the false data and sharply altered the plane’s course, with near disastrous results. It was later learned that the same plane had experienced a similar occurrence in September 2006, as had three other flights. All those planes carried the same brand and model of ADIRU, as do more than one-third of the 330s and 340s in the Airbus fleet. So if this model of ADIRU has a history of failure, why does Airbus continue to fit them in its 330s and 340s? According to Airbus spokesman Justin Dubon, any comparisons between the Qantas and Air France flights are fundamentally misleading. “One thing that has got to be clear is that there are more than one manufacturer of ADIRUs, and the ADIRU manufacturer for the Qantas case is not the same for the Air France case,” he tells TIME. As reported in the aviation trade magazine _Air Transport News,_ manufacturer Northrop Grumman makes the ADIRUs for Qantas, and Honeywell for Air France. “There are no similarities in ADIRUs between the two cases,” says Dubon. ([Q&A: How to survive a plane crash.](https://www.time.com/time/nation/article/0,8599,1872154,00.html)) As for the Qantas 330s and the rest of the Airbus 330 fleet, Dubon says they will continue to fly with their same ADIRUs until directed otherwise by investigative authorities. “The \[Qantas\] investigation is still ongoing, and we’re still involved in giving technical assistance to that, but no final recommendations have been made,” he says. “And obviously, when the investigators do, then we will act on those.” But even if there are recommendations to be made, it’s unlikely they will come anytime soon. According to an aviation source close to the Australian investigation, Qantas remains perplexed by the phenomenon, finding that since October 2008 that particular A330 has never suffered a repeat ADIRU failure, even when flying the same routes under similar conditions. “So it’s something they need to get to the bottom of,” says the industry insider, who requested anonymity. “Because it’s so unpredictable — it happens one time, and then never happens again — they’re still trying to work out what it is.” The Airbus 330 is not the only model to suffer ADIRU failures. An Airworthiness Directive issued by the U.S. Federal Aviation Administration last year warned airlines of instances of failure in ADIRUs aboard Airbus 319, 320 and 321 models that “could result in loss of one source of critical altitude and airspeed data and reduce the ability of the flight crew to control the airplane.” Dubon says these issues are “totally unrelated … Our safety people have informed me that is not relevant to either the Qantas case or the Air France case.” But some people have firsthand experience of ADIRU failures on Air France flights: Air France pilots. Julien Gourguechon, International Secretary General of the French Pilots Union (SNPL) and an Air France pilot of 10 years, says ADIRU failures are not foreign to him, his colleagues or other French pilots flying for other companies and the military. “For sure there are pilots from SNPL who have experienced ADIRU problems,” he says. But, he adds, this is “very rare … You don’t have more fly-by-wire technical failure with them than you do with hydraulic, mechanic or engine failure.” As for Flight 447, even if the plane’s ADIRU did malfunction, an electrical short circuit or other problem may actually be to blame, he says. “The ADIRU is fed by a lot of sources, and the failure of one of these sources could lead to an ADIRU failure.” For now, Gourguechon finds the endless speculating exhausting. “Initially we were talking about electrical failure, yesterday we were talking about icing conditions, tomorrow we will talk about something else,” he says. “ADIRU failure is as credible as very bad weather, hail, an electrical failure. I would not give priority to one scenario.” But until investigators figure out what happened — if they ever do — Gourguechon says there’s little chance we’ll be able to escape the realm of the hypothetical. “The biggest fear for us is that if we don’t find the \[flight\] recorders, then all the analysis, even made by experts and professionals with all the time they need, runs the risk of being very incomplete and based on a lot of interpretation.” [See TIME’s Pictures of the Week.](https://www.time.com/time/picturesoftheweek) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6946885/could-a-computer-glitch-have-brought-down-air-france-447/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6946885/could-a-computer-glitch-have-brought-down-air-france-447/"},"headline":"Could a Computer Glitch Have Brought Down Air France 447?","datePublished":"2009-06-05T04:00:00.000Z","dateModified":"2026-04-22T07:29:29.343Z","description":"As the French team leading the investigation into the Air France Flight 447 crash works through the multitude of likely and less likely disaster scenarios...","url":"https://time.com/archive/6946885/could-a-computer-glitch-have-brought-down-air-france-447/","keywords":[],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd480d68d9c9f55bf/698a51b2b3fce3b2710ccbd2/360_crash_inquest_0604.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Jeffrey T.
