(6) Organization requesting DF assistance. The net usually continues alert status for aircraft forced to ditch, or crash land, to obtain bearings on emergency radio beacons or crash position indicator (CPI) radio beacons. The net control station de-alerts the net automatically when the emergency is over. F. The Federal Communications Commission (FCC) operates a 400 kHz to 40 MHz Direction-Finding Net that covers the inland United States, the Pacific Ocean and the Atlantic Ocean. A Watch Office in Washington D.C. monitors MF, HF, and VHF distress calls 24 hours a day. The FCC also operates field offices with personnel who can locate ELTs and EPIRBs using mobile and portable DF equipment. FCC services should be used for urgent SAR only and are generally not available to the public. 1. SMCs may activate the net by calling the FCC Watch Officer at 202-632-6975, or the nearest FCC office during normal business hours, and providing the same information needed to alert the FAA net. SMCs should ensure the FCC net is de-alerted as soon as possible after the distressed unit is located. 2. The FCC net provides an elliptical area containing the most probable location of the distress and the longitude and latitude of the ellipse's center. While the net usually does not provide DF bearings with a fix, SMCs should request all available bearings. G. The National Transportation Safety Board (NTSB) based on the requirement to rapidly locate recorded radar data in conjunction with accident/incident investigations, developed a computer program containing a database of all U.S. Civilian (FAA), U.S. Military, and Canadian (civil) ground based radars capable of providing recorded radar data. The program, known as RADARFIND (RADF), provides the user with a listing of all radar sites with 2-15

the potential for recording data within range of the sites. The individual site listings provide identification of the owning facility (3 letter designator), along with true bearing (degrees) and nautical mile distance regarding a specific latitude/longitude listing. The latest version of the RADF program is used by AFRCC. Additionally, the program has been provided to the other U.S. and Canadian operated RCC's in an MS/DOS format. The RADF is updated as required and additional MS/DOS copies are available to recognized SAR organizations upon request. The RADF program may be ordered through: NTSB (TE-30) ATTN: RADF 800 Independence Avenue, S.W. Washington, DC 20594 When ordering specify: IBM PC-MS/DOS 360K (5 1/4") or 720K (3 1/2") format or TANDY2000 720K (5 1/4") format. 2-16
