  ETA
  6-181. Enter the estimated time of arrival, estimated TOT, or S3 air brief. Use the same unit of time
  throughout the form.
  ATA/ATD
  6-182. Enter the actual time of each pass or the actual time of departure.
  STRIKE REPORT
  6-183. The strike report yards or clock is the actual purpose of this form. Observe the first
  parachute-suspended item from the control center, and then determine the distance in yards and the clock
  direction relative to the PI. Use 12 o'clock as the magnetic drop heading. If the first parachute lands within
  25 yards of the PI, then write "PI" here to indicate a PI strike. If you were unable to maintain visual contact
  with the first parachute, especially during a multiple aircraft operation, then score the drop "S"
  (satisfactory) or "U" (unsatisfactory). If 90 percent of the parachutes land on the DZ, score the drop as
  satisfactory. If less than 90 percent hit the DZ, score it unsatisfactory. If you maintain radio
  communications with the drop aircraft, then relay strike reports to them so they can adjust their subsequent
  passes accordingly.
  YDS
  6-184. If the first jumper, container, or pallet lands within 25 yards of the PI, write "PI." If it lands farther
  from the PI, enter the distance from the PI in yards.
  CLOCK
  6-185. Use the direction of flight as 12 o’clock and its back azimuth as 6 o’clock. Estimate the direction
  from the PI to the first jumper, container, or pallet. If you can, enter the actual measurement.
  LZ
  6-186. Mark the “S” (satisfactory) box if a landing occurred in the first 500 feet of the LZ. If the aircraft
  had to go around again, if the drop fell short of the touchdown zone, or was more than 500 feet from the
  beginning of the touchdown zone, mark the “U” (unsatisfactory), and comment in Remarks.
  SURF WIND
  6-187. Enter the surface wind direction in degrees. Enter the highest wind velocity measured during the
  10 minute window for that pass.
  SCORE METHOD
  6-188. Select from the Legend the abbreviation for the method you use to determine the distance between
  the PI and the first parachute.
  y E = Estimated (You made a calculated guess).
  y P = Paced (You paced off the distance).
  y M = Measured (You used a calibrated measuring device to determine the distance).
  MEAN EFFECTIVE WIND
  6-189. Enter the time you measured the wind and the altitude where you measured it.
