COMMUNICATION CAN BE INITIATED BY GROUND TROOPS OR AT REQUEST OF AIRCRAFT SUCH AS AIRCRAFT REQUEST OF LOCATION AND IDENTIFICATION OF UNIT COMMAND POSTS. DISPLAY GROUNDS: PANEL DISPLAY GROUNDS ARE LOCATED NEAR THE RADIO STATION SINCE THE RADIO OPERATORS ARE NORMALLY ALSO THE PANEL OPERATORS. THE PANEL DISPLAY GROUND SHOULD BE A FAIRLY LEVEL OPEN SPACE FREE FROM ROCKS, HIGH WEEDS, AND BRUSH, REMOVED FROM HIGH TREES AND BODIES OF WATER. IT SHOULD BE DEFILADED FROM HOSTILE GROUND OBSERVATION BUT SO LOCATED THAT THE PANELS CAN BE SEEN BY AIRPLANES AT WIDE ANGLES FROM THE VERTICAL. THE PANELS SHOULD BE DISPLAYED IN THE BEST LIGHT AVAILABLE AND SO PLACED THAT SHADOWS WILL NOT FALL ACROSS THEM BLURRING THEIR OUTLINES TO THE AIR OBSERVER. CARE MUST BE EXERCISED TO SEE THAT PANELS ARE DISPLAYED ONLY TO FRIENDLY AIRCRAFT WHO HAVE IDENTIFIED THEMSELVES AS SUCH BY USE OF A PREARRANGED SIGNAL. UPON THE APPROACH OF HOSTILE AIRCRAFT, THE PANELS SHOULD BE TAKEN UP OR CONCEALED. TECHNIQUE OF PANEL DISPLAY: NO HARD AND FAST RULES GOVERNING THE SPACE THAT MUST BE LEFT BETWEEN THE PANELS COMPOSING ANY SIGNAL CAN BE LAID DOWN. THE DISTANCE BETWEEN ALL PANELS SHOULD BE DICTATED BY LOCAL CONDITIONS AS TO VISIBILITY, SPACE AVAILABLE, HEIGHT OF THE AIRPLANE, AND THE TERRAIN. PANEL OPERATORS WHEN PREPARING TO DISPLAY- PANELS WILL, ACCORDING TO THE NUMBER OF OPERATORS AVAILABLE, POST THEMSELVES IN SUCH POSITIONS AS WILL FACILITATE LAYING OUT, CHANGING, AND TAKING UP PANELS WITH THE GREATEST POSSIBLE SPEED AND PRECISION. WHEN THE DISPLAY OF ANY SIGNAL HAS BEEN COMPLETED, OPERATORS MOVE AWAY FROM THE PANELS RAPIDLY AND TAKE UP SUCH POSITIONS THAT THEY WILL NOT OBSCURE THE SIGNAL FROM OBSERVATION OR CAST SHADOWS UPON ANY PART OF IT. THE SIGNAL REMAINS DISPLAYED UNTIL THE AIRPLANE'S ACKNOWLEDGMENT HAS BEEN RECEIVED, WHEREUPON ALL PANELS NOT IN THE INITIAL DISPLAY WILL ALWAYS BE REMOVED BEFORE A NEW DISPLAY IS MADE.
