The system includes a processor, memory, and a display. The processor is capable of communicating with the memory, the display, and a system environment of the aircraft. The processor is configured to display a flight map for the aircraft on the display, to evaluate state variable(s) dynamically representing state(s) in the aircraft system environment, and dynamically modify the flight map based at least in part on the evaluation. ## Claims ### Claim 1 A navigational information display system for dynamically displaying and modifying context-aware craft navigational information during operation of the craft, the system comprising: one or more computer processors;
