Flight guidance system and symbology and control system providing perspective flight guidance

摘要

A flight guidance system providing perspective flight guidance symbology using positioning and terrain information provides increased pilot situational awareness of the pilot's aircraft. The guidance system uses a positioning system and a detailed mapping system to provide a perspective display for use in an aircraft. A precision pathway flight guidance (PFG) symbology set is thereby displayed on a pilot display. The PFG symbology set includes broken line symbols representing an open tunnel and providing flow field data, a half-bracket symbol to indicate that the aircraft is no longer in the open tunnel represented by the broken line symbols and a quickened flight path vector (QFPV) symbol to provide the pilot with predictive flight path information. A flight director system and tunnel generator component provide for updating the displayed PDFG symbology set based upon current aircraft conditions (e.g., aircraft position) and stored flight path information.
