Overthewing, any pilot that doesn't consider every possible failure and how to handle it shouldn't be flying. There is not enough time to train him for every possibility. He needs to think about it himself while he is droning along or driving to work. One of the best ways is to look at accident reports and put yourself in their shoes and decide what you will do if it happens to you. It has saved me numerous times. 23,000 hrs and never making the papers or an accident report was because of that.....and a bit of luck.
