The Down Loads in the sections below represent 11 trips to Alaska. Each trip they get a little more refined but they now are at a point where the information is critical in increasing the safety of your trip. I have always been shocked on how little some pilots know about their GPS and navigating in remote areas. They are ok from airport to airport but not lake to lake. It is hoped this information and some training on your GPS will make a big difference in on your Alaska adventures.
