Hello. I am not in aviation business so this will be my only post unless I get a legitimate reason to reply.
I have dealt with depression for most of my life. Psychiatrists, antidepressants in the past, etc. I have learnt to live with it and I just accepted it that I might have some down times. I have never been suicidal, neither I ever had a wish to harm another. I believe depression is sometimes misunderstood and it doesn't automatically make you unreasonable. However when a major event happened I needed some time off, to regroup it was overwhelming. At that time I would definitely be of no help to my company.
I work in restaurant business, I am a chef. My work is nowhere as hazardous as being a pilot and I have no intention to compare it. I only want to make a reference to human nature.
We do get hectic times when work demand goes over your head and you have to know how to keep your calm. When that happens I am usually a top performer and hardly ever loose my nerve. At the same time I observe my "sane" coworkers loosing it completely. Many times I wondered why. It might only be that I am more aware becouse of all the terapies and other people act unconciously and are emotionaly unprepared for the situations. I don't know.. I believe we all have our boiling point wich a certain amount of stressors can trigger.
I have absolutelly no idea how a pilot training works, but maybe having a mandatory psychological class and mental training and observation by specialist until you reach a certain amount of experience could be a solution. By that time you should have enough experience to act confidently in the pilot seat, understand yourself and ofcourse being screened, for hazardeus behavior. Scool should mybe be free of charge for those who do not pass.
