A flight deck system for providing task management assistance in managing the flight path to the flight crew is provided. The system is configured to: mine flight plan data for a current flight plan, navigational data, and vertical situation display (VSD) data; obtain notification data items originating from onboard avionics systems and systems external to the aircraft that indicate upcoming conditions that will affect the current flight plan; automatically analyze the mined flight plan data and the notification data items to identify a sensed deviation condition; automatically identify an aircraft-related deviation condition from an aircraft failure event; receive flight crew notification of a non-sensed deviation condition; automatically generate a plurality of flight plan deviation options to accommodate a sensed deviation condition, an aircraft-related deviation condition, or a non-sensed deviation condition; and present graphical elements representative of the flight plan deviation options to the flight crew on an integrated interactive graphical user interface.
