Methods, systems, and apparatus for tab-pane-based flight plan management interface are disclosed. The tab-pane-based flight management interface system (FMIS) is optimally Layered and Multi-Indexed (LMI) such that the management of flight management (FM) functions and associated parameters that affect the airplane's flight are easily and efficiently operable by pilots. The LMI-FMIS provides a flexible tab-pane-based architecture that allows pilots to start a flight plan modification, proceed to engage in other tasks not related to the modification, and return to the pending modification to continue the modification process. The LMI-FMIS also provides task-oriented menu structures that provide pilots tailored options or menus applicable to the task at hand thus efficiently guiding pilots to complete a task while maintaining easy access to information that was displayed prior to the commencement of the task.
