Real-world perspective display for use with an independent aircraft landing monitor system
Abstract
Abstract A RADAR DISPLAY FOR AN INDEPENDENT AIRCRAFT LANDING MONITOR WHEREIN A RADAR SYSTEM ONBOARD AN AIRCRAFT DETECTS AN AIRPORT RUNWAY DURING GLIDESLOPE APPROACH. THE DISPLAY INCLUDES A RADAR DISPLAY TUBE HAVING HORIZONTAL AND VERTICAL SWEEP CIRCUITS FOR CONTROLLING THE VISUAL DISPLAY OF THE TUBE. CIRCUITRY OPERATES THE HORIZONTAL SWEEP CIRCUITS OF THE DISPLAY TUBE IN SYNCHRONISM WITH THE AZIMUTH SCAN OF THE RADAR SYSTEM. CIRCUITS ARE RESPONSIVE TO THE AIRCRAFT ALTITUDE FOR GENERATING A DRIVING OUTPUT SIGNAL WHICH VARIES NON-LINEARLY IN AMPLITUDE WITH RESPECT TO THE RATIO OF AIRCRAFT ALTITUDE AND RADAR RANGE. CIRCUITRY IS RESPONSIVE TO THE DRIVING OUTPUT SIGNAL FOR CONTROL OF THE ELEVATION ANGLE DISPLAYED BY THE VERTICAL SWEEP CIRCUITS OF KTHE RADAR DISPLAY TUBE TO THEREBY GENERATE INDICATIONS OF THE APPROACHING AIRPORT RUNWAY IN REAL-WORLD PERSPECTIVE. PROVISION IS ALSO MADE TO SELECTIVELY DISPLAY CONVENTIONAL B SWEEP OR PPI DISPLAYS OF THE APPROACHING AIRPORT RUNWAY, AND RANGE MARKER SIGNALS ARE DISPLAYED UPON THE RADAR DISPLAY TUBE DURING GLIDESLOPE APPROACH.
