Abstract: A computer-implemented method performs event-centric navigation and planning for a user including: compiling a database of known events related to a field of endeavor in a database server computer; receiving input data from the user identifying at least one of: a selected date and a selected locus; identifying for selection a group of events based on the input data received from the user; selecting an event within the group from the database of known events; planning a trip to the selected event; and displaying a navigation aid to the selected event. Methods include coordinating the activity of event attendees includes: recording in a database an indication of interest in an event by a potential attendee; and geo-locating in real time another potential attendee of the event.

Abstract: The present application provides systems and methods for providing navigational guidance during off-course operations, and techniques to revert back to a desired flight destination upon completion of such operations. In one aspect, an aviation navigational and/or flight management system is configured to alter guidance instructions from a predetermined flight plan for a desired destination to a particular set of radar vectors resulting in off-course flight operations. In another aspect, the system is configured to recalculate a flight plan to the desired final destination upon completion of the off-course operations without resulting in the loss of current historical flight data.
