Next, I suggest you stop somewhere along the way that is well outside the beehive to collect your thoughts, but close enough that you'll be fresh when you arrive at the final destination — about a half hour's flight time works for me. I figure I don't want to be entering a time of high alert after I've been lulled by several hours of cruise flight. Also, it's a chance to top off fuel tanks so you have absolutely no worries about holds or other delays in the air. Another point, if you have another pilot on board, have a chat about who will be responsible for what. For non-pilot passengers, brief them on spotting traffic and how you'd like to be alerted. For example, make sure they know how to gauge relative altitude and recognize the danger zones — ahead and on the horizon. That way, you can be confident they won't be shrieking with horror because they spotted an airliner's contrail 30,000 feet overhead.
