What connects Swiss cheese with decision-making and stress management? Clue: it's not the plight of an Alpine dairy farmer whose cows aren't yielding as much milk as in previous years. These are all things you will learn about as part of Crew Resource Management (CRM) training. Even though these might seem trivial, amusing, or at times bizarre, these are components of a CRM course that have saved many lives and improved overall safety since its formal development in 1979 and widespread adoption in the early 1980s.
So, why was CRM introduced in the first place?
Just another box to tick for our overworked pilots and instructors? Unfortunately, that was definitely not the case. Sadly—as with the introduction of so many reforms—CRM was a reaction to multiple accidents, including the Tenerife Air Disaster on March 27, 1977, which remains the deadliest aviation accident in history. Inadequate cockpit communication and poor coordination were identified as contributing factors. This and other incidents prompted NASA to hold a workshop in 1979 on flight deck management, leading to the development of CRM as a structured training program. Airlines began adopting CRM in the early 1980s as a means to enhance safety and prevent similar disasters.
At its core, Crew Resource Management (CRM) is all about making the best use of every available resource—people, equipment, and procedures—to enhance safety and efficiency. The idea is simple: aviation is a team effort, and a well-coordinated team is far less likely to make critical errors. Here's what ICAO has to say about CRM...
the effective use of all available resources—human, hardware, and information—to achieve safe and efficient flight operations.
ICAO definition of CRM
CRM focuses on key skills such as communication, situational awareness, decision-making, teamwork, and managing workload under pressure. It is anything but just a passing trend; it has completely transformed cockpit culture. Gone are the days of rigid hierarchies where questioning a captain was unthinkable (the so-called "Captainitis"). Instead, CRM encouraged open communication, where even the most junior crew members were empowered to speak up if something didn’t seem right.
In fact, since its introduction, CRM has evolved and expanded beyond aviation into industries where teamwork and communication can mean the difference between success and disaster. Industries like these:
Today, CRM isn’t just best practice—it’s a regulatory requirement. Aviation authorities worldwide, including ICAO, EASA, and the FAA, mandate CRM training for flight crews, cabin crews, and air traffic controllers. It forms a core part of initial and recurrent training programs, ensuring that the principles of teamwork, communication, and decision-making are at the heart of aviation safety. Sometimes, when we think of 'regulatory requirements', we view them as yet another case of "having to do" something, rather than "seeing the value in doing" things. With CRM, that is certainly not the case.
CRM Inaction vs. CRM In Action
Let's take a look at two cases: one where CRM was absent, and the other where CRM was present. For the "CRM-Sceptics" or the "Yet-to-Be Converted," these cases will illustrate how bad things could be if it were not for the adoption of CRM in all airlines.
Case Study One:
Eastern Flight 401—A Failure of CRM
While the decision to perform a go-around was correct, the failure to monitor the flight instruments during this critical phase of flight ultimately led to the accident. Eastern Flight 401 is just one of too many examples of why CRM was introduced and why it is so important in ensuring the safety and efficiency of flight operations.
Case Study Two:
2003 Baghdad DHL Incident—CRM Saves Lives
Now that we've seen the effects of poor CRM practices, or the complete absence of CRM, let's take a look at a case where thanks to the introduction of CRM and its effective implementation, it actually saved lives against all odds.
The Present and Future of CRM Training
Modern CRM training integrates CBTA (Competency-Based Training and Assessment) to ensure pilots and crew members not only learn CRM concepts but also get plenty of opportunities to demonstrate how they apply in practice.
At Evionica, not only do we adhere strictly to EASA regulations, which frequently require elements of CRM, such as human factors, to be implemented in other courses, but we also design CRM courses that address the modern learner, incorporating the latest research and best practices in CRM. We provide:
CBTA-Aligned Simulations – Real-world CRM application scenarios with measurable competencies.
Case Studies with Competency Evaluation – Incident analysis with performance-based assessment.
Scenario-Based & Adaptive Learning – Progressive learning paths that adjust to individual performance.
Role-Playing with Measurable Outcomes – CRM skills tested through structured role-play.
Formative & Summative Assessments – Competency-driven testing and constructive feedback mechanisms.
Expert-Guided CBTA Coaching – Direct learning from experienced CRM professionals.
Interactive & Performance-Based Tools – Engaging, trackable learning methods that go beyond theory.
Continuous Content Updates – Ensuring alignment with evolving CBTA and CRM best practices.
Multilingual & Culturally Adaptive Training – Supporting global competency development.
By making sure CBTA principles are left, right, and centre of CRM, we ensure CRM training is practical, competency-driven, and continuously evolving to meet the demands of modern aviation.
Final Thoughts
CRM is a broad subject covering leadership, collaboration, cultural differences, generational differences, stress management, pilot incapacitation, the 'surprise and startle' effect, and much more. As we've seen, it has revolutionized safety in aviation and beyond. At Evionica, our CRM eLearning course ensures learners receive modern, interactive training that is fully compliant with EASA regulations and adaptable to evolving best practices.
It will come as no surprise, and you will hopefully not be startled, that our CRM eLearning course is accessible on all devices, anytime, anywhere, 100% compliant with EASA regulations, and fully aligned with modern CRM training requirements and the modern learner. Safe flying with your crew!
