Take a lesson from the Jedi......Relax, Concentrate, Visualise success. Imagine all of the correct physical and verbal responses to the emergencies/abnormalities AFM/SOP challenges etc. Sit in an empty cockpit/training device/or go jogging and get the responses memorized calmly. It worked for me when I was way past my prime in premier division rugby. (I got awards in my late 30's)
I'm also a medivac captain in the Canadian north operating a business jet.
The similarities between sports and flying made me realize that this is 90% a mental game.
