"The best emergency is the one you're not in." - Division7, Special Projects Group.

60-65% of aviation mishaps are attributable to human error, and approximately 90% of those errors stem from poor judgment and inattention.

When cockpit crews operate under excessive workloads, they are prone to impaired decision-making, loss of situational awareness, and degraded problem-solving abilities.

Essentially, they start to lose their marbles.

With the improvements in the quality and reliability of today's aircraft, powerplants, and systems, cognitive failures, rather than technical malfunctions, have become the primary contributors to contemporary aviation accidents and incidents.

Acknowledging this, the SPG sought to determine whether elective Evidence-Based Training (EBT) modules would be effective in demonstrating the latest methods for controlling and reducing crew workloads.

EBT in aviation is a safety-focused approach that relies on research and evidence to design and deliver practical aircrew training exercises, tailored through data-driven analysis of real-world operational events.

Through a series of No-Risk/High-Gain elective exercises, crews can experience non-jeopardy, high-workload situations that can be demonstrated, practiced, and repeated as often as desired.

At the start of the series, each participant is issued a personalized cloth sack. Upon completion of each module in the series, as well as other elective simulator exercises, one marble is issued, to kept in the sack along with all the other marbles acquired through subsequent training exercises. Up to a maximum of 25 marbles.

The idea being that if some unexpected events occur that require the use of some marbles to address them, there will always be some marbles remaining in the bag, hopefully preventing
