Pilots and Mechanics - AnswerThe movie below will solve the problem for you. It goes one step at a time. Each step is numbered for reference. Similar to the Aces on top puzzle all you have to do is follow th rules. For the first move there are two moves that fall within the rules, either two Pilots cross the river and leave on on the other side, or as shown below, one pilot and one AME cross the river, leaving the pilot on the other side. After that there is only one "legal" move you can make at each step. Almost always people who don't solve the problem fail at step 7. Watch the animation, then we will discuss why step 6 is so psychologically difficult for people.
Is there a CRM principle involved?Yes. There are two key CRM principles. The first is the same as in Aces on top; that if you follow a good set of rules you can solve a complex problem safely. Your choice for the first crossing will make no difference as long as you choose a move that does'nt violate the rules. The second CRM principle is perhaps more important. Never be over committed to progress already made. Most people who don't solve the problem fail at step 7. At that step you must undo something already done. I.E. take a pilot back to the first shore. It is the only move permitted under the rules, but many people get stuck at that point and want to cheat - for example leave two pilots with the one mechanic (that seems to them to be the only thing to do.) The same thing happens to many pilots in flight when circumstanceS change that require a turn back to a previous destination. If our destination is in front of us it is very hard to go back, even if the rules really require it. (the main "rules" being referred to here are the rules of common sense, although regulatory rules come into play also.) Psychologically, retreat is hard to do. But, from time to time you will have to do it if you are a professional pilot. Learn to see a retreat decision as the wise solution to a complex riddle - something you should be proud of doing. Never see it as a failure. Those who don't retreat when circumstances demand it are "cheating" (either the regulations, or fate, or both.)
