text: Helicopter Landing Zones
  movement commander staffs the RP only when he expects tough navigational problems. He tentatively
  chooses its location from maps or from aerial photographic studies. He looks for an easily-identifiable
  point on the planned flight route to the landing site. He looks for a location that will take advantage of
  long-range electronic and visual navigation aids.
  4-29. For single helicopter landing sites within a single LZ, the site itself offers the best location for
  GTA communication. Especially at night, positioning here allows the pathfinder air traffic controller to
  observe the final approach of helicopter formations. It helps him make sure pilots align correctly on the
  required landing direction. It also helps him ensure that they clear any obstacles.
  4-30. The pathfinder leader organizes the control center to meet mission requirements. The control center
  can consist of a single pathfinder. This Soldier can operate the GTA radio for a limited period at a small
  site, or the control center can consist of the following staff:
  LZ OR DZ COMMANDER
  4-31. He supervises aircraft landings and departures, airdrops, and other pathfinder activities in the LZ or
  DZ. He might also serve as the GTA radio operator.
  GTA RADIO OPERATOR
  4-32. He operates the radio used to maintain communications with pilots. He also provides advisories for
  his airspace as needed.
  INTERNAL NET RECORDER
  4-33. Some situations require pathfinders to set up an internal net to communicate with other pathfinder
  elements. An internal net recorder (INR) runs this net and helps control aircraft at his HLZ. He logs details
  of all arrivals and departures on DA Form 7461-R, Internal Net Record, (Figure 4-7, page 4-12). If an
  aircraft fails to arrive at its destination, search and rescue medical units check the DA Forms 7461-R so
  they know where to focus their search. The recorder might copy the blank, reproducible form from the
  back of this manual onto 8½ by 11-inch paper. He might also download it from http://www.usapa.army.mil
  or copy it from the Army Electronic Library (AEL) CD-ROM (EM0001). Then he completes the form
  as follows:
  PFDR Det. Write the name of the pathfinder detachment operating the landing zone.
  Supported Unit. Write the name of the supported unit.
  Period (DTG). Write the date and time of the mission.
  Operation. Write the name of the mission.
  Designation. Write the name and location of the site.
  Recorder. Write your name.
  No. A/C. Write the number of aircraft in the formation.
  Type A/C. Write the nomenclature of each type of aircraft in the formation.
  Contact Time. Write the time of the initial contact with the flight commander.
  Call Sign. Write the flight commander's call sign.
  Time, Arr. Write what time the aircraft or formation inserted.
  Time, Dep. Write what time the aircraft or formation extracted.
  Load Type, Ins. Write what type of load the aircraft inserted.
  Load Type, Ext. Write what type of load the aircraft extracted.
  Destination. Write the name of the aircraft's or formation's destination on leaving.
  Remarks. Write anything else here that you think you need to record.
