I perceive the bigger danger here is not that we miss existing psychological conditions that affect pilots. Instead, my opinion (FWIW) is that increasing the pressure on pilots, and the intrusion of monitoring into private lives will drive some pilots into conditions that were NOT existing.
I agree absolutely that there needs to be a wholesale improvement in pilot support systems, and that pilots should be able to seek appropriate support and/or treatment for mental health issues. Just the same way as it is currently possible for physical health issues.
I just can't see that moving further down the road of intrusive monitoring linked to career-guilotines is going to achieve the intended result of reducing what is already a VERY rare situation.
