Part 91.103 states that if you are acting as PIC you must obtain weather reports and forecasts if you are flying VFR and not in the Vicinity of an airport. So... What does vicinity mean? Does Vicinity mean in the traffic pattern or does vicinity mean up to a particular distance from the departing airport, or an airport, such as within 25 miles of an airport or the departing airport? If you know Please respond and please list your sources. Thanks so much in advance.
