Abstract: A system and method for augmenting synthetic vision system (SVS) databases with spectrum diverse features that are matched to the observations of natural scenes derived from non-visible band sensors. The system correlates sensor output with a-priori information in databases to enhance system precision and robustness. Multiple diverse sensors image naturally occurring, or artificial features (towers buildings etc.) and store the multi-spectral attributes of those features within the enhanced multi-spectral database and share the information with other systems. The system, upon “live” observation of those features and attributes, correlates current observations with expected fiducial observations in the multi-spectral database and confirms operation, navigation, precise position, and sensor fidelity to enable autonomous operation of an aircraft employing the system.

The processor-executable code causes the processor to receive a user input from a user interface element of the aircraft where the user input requests updated weather information. The processor-executable code causes the processor to retrieve, via the communications system and in response to the user input, updated weather data from the remote source; calculate a departure or arrival performance flight parameter based at least in part on the updated weather data; and provide, via the display system, an output for the flight display of the aircraft where the output includes the flight parameter.
