Claim:
A method of providing precision course guidance, such method comprising: performing the following elements, where such elements are performed by a processor installed in an aircraft system: generating a hazard-free path from data retrieved from at least one database, where the hazard-free path is a path free from a plurality of charted hazards defined with fixed locations; displaying the hazard-free path and the plurality of charted hazards on at least one flight deck display; generating egocentric guidance cues that enable a pilot to fly the hazard-free path; displaying the egocentric guidance cues with the display of the hazard-free path and the plurality of charted hazards; detecting at least one uncharted hazard defined by a fixed location with at least one onboard, real-time sensor; generating a notification of database error when at least one uncharted hazard is detected; and sending the notification of database error to an onboard crew alerting system, whereby at least one alert corresponding to the database error is presented to the pilot.
