  Advisory Information
  3-59. See Table 3-7.
  Type of Advisory Information Included
  FLIGHT The enemy situation, if it presents a threat to the aircraft.
  LANDING Surface conditions on the landing site such as the presence of
  sand, mud, or blowing snow.
  DEPARTURE Obstacles in the path of aircraft leaving the site (obstacles above
  the obstacle departure lights).
  Table 3-7. Information included in advisories.
  Aircraft in Sight
  3-60. The following shows what the pilot and pathfinder say when an aircraft is in sight of the runway:
  Pathfinder: BRAVO TWO SEVEN, THIS IS LIMA ONE SIX, I AM AT YOUR
  TWELVE O'CLOCK, FIVE HUNDRED METERS, IDENTIFY SIGNAL,
  OVER.
  Pilot: THIS IS BRAVO TWO SEVEN, I IDENTIFY GREEN SMOKE, OVER.
  3-61. At night, during specialized activities such as external load drop-off or pickup, or when unsafe
  surface conditions require pathfinders to mark specific landing points, the flight leader must know all
  arrangements. This allows him to organize the flight for landing. Pathfinders identify the site by flashing a
  visible or infrared light source in a dot-dash sequence.
  Pathfinder: THIS IS LIMA ONE SIX, VISUAL CONTACT (and, once the pilot
  identifies the site), WIND THREE TWO FIVE AT EIGHT, CLEAR TO
  LAND, OVER.
  3-62. Once the pilot identifies the site, the pathfinder issues final landing instructions. If the controller
  already has other aircraft flying in a traffic pattern, he places the incoming aircraft into the traffic pattern at
  a safe and convenient location. Then, he instructs the pilot to report base. When the pilot reports base, the
  pathfinder issues final landing instructions. For special situations, instead of placing the aircraft in the
  traffic pattern, the controller might tell the pilot to circle left or right. Then the controller will issue final
  landing instructions.
  Departure Instructions
  3-63. If the departure heading differs from the land heading, the controller gives the departure heading
  as the first element of the departure instructions.
  Pilot: LIMA ONE SIX, THIS IS BRAVO TWO SEVEN, READY FOR
  DEPARTURE, OVER.
  Pathfinder: THIS IS LIMA ONE SIX, WIND THREE TWO FIVE AT EIGHT, CLEAR
  TO DEPART, STATE INTENTIONS, REPORT CLEAR OF LANDING
  ZONE, OVER.
  Pilot: THIS IS BRAVO TWO SEVEN, RIGHT BREAK, AFTER DEPARTURE,
  OVER.
  Pathfinder: THIS IS LIMA ONE SIX, ROGER, OVER.
  Pilot: THIS IS BRAVO TWO SEVEN, CLEAR TO THE WEST, OVER.
  Pathfinder: THIS IS ALPHA ONE LIMA ONE SIX, ROGER, OUT.
