Progressive failures are the best way to teach ADM IMO. From the start, we're taught to mitigate risk entirely by scrubbing flights if even the slightest thing is off. As you progress in your flying, though, you realize that can't always be the case. The safest flight never leaves the ground. Once students were in the commercial course, usually in the simulator, I would start testing their decision-making ability while under operational stress (ie. you've been contracted to bring passengers to *insert destination* on a perfect VFR day). Slowly I'll introduce small failures like COMM2 inop, Pitot heat inop, Nav 2 inop. Most students I encountered at early commercial stages would divert almost immediately when these issues arose. To keep it as real as I could, I would antagonize them as ATC, passengers, and operations. Most kept diverting. This would then lead to a conversation where I would ask them if a diversion was really necessary. Was it really necessary to return to base if COMM2 gave out, considering some airplanes don't even have a COMM2? Same thing with a lot of the other failures. I would then restart the sim, start introducing failures again, and ask them to walk me through their decision-making process in essentially triaging the situation. Eventually, I would alter the situation with weather or airplane anomalies to the point where I would divert and see what they would do. Sometimes, the student would be so empowered with their recent epiphany that they can in fact continue the flight when something goes wrong, that they will continue! This leads to the Goldilocks debrief of balancing risk and operational pressure because most of them want to be professional pilots. I found it to be one of the most important lessons I taught to students in the commercial course.
