2. Alert SAR facilities of a possible mission but do not dispatch SRUs immediately. 3. Investigate further either the validity of the incident or the degree of SAR system support needed. B. SRU selection is determined by case evaluation, SRU availability and distance from scene, and their capability of providing rapid and effective SAR services: 1. Aircraft normally provide better search platforms because they can cover an area more quickly and effectively. 2. Helicopters may provide the quickest form of assistance when recovery and transport to a medical facility are needed. 3. Boats and land vehicles can provide quick response close to their geographical location, and normally have more survivor space and unique SAR capabilities. 470 COMMUNICATION SEARCHES SMCs conduct communication searches when facts are needed to supplement initially reported information. SRU movement to check potential areas of craft location may be necessary. Communication searches continue efforts to contact the craft, determine whether the craft is overdue or simply unreported, better define the search area, and obtain more information for determining subsequent SAR action. The two types of communication searches are the preliminary communication search (PRECOM) and the extended communication search (EXCOM). They are usually conducted sequentially. 4-9
471 PRECOM A. PRECOM search contacts major facilities where the craft might be or might have been seen, and is normally conducted during the Uncertainty phase. PRECOM establishes limits for the area to be covered during EXCOM or physical search efforts, and should be conducted as quickly as possible. Each facility should be contacted only once, and the SMC briefed when PRECOM is completed. B. PRECOM efforts for marine craft will vary depending on the type of craft. 1. Contacts may include the following: a. All dedicated SAR facilities in the area for any information in radio logs and records. b. Bridge and lock tenders. c. Local harbor patrols, harbor masters, and dockmasters. d. Marinas, yacht clubs, and other waterside facilities, such as ice and fuel supplies, chandleries, repair yards, fishing concerns, and vessel agents. e. Tug companies and fishing vessels. f. Local police, pilot boats, customs and immigration authorities. g. Relatives and friends. 2. If the missing craft is known to have a radio aboard, appropriate facilities should attempt contact. Marine operators in areas being searched should be asked to check their logs for information on the search objective. Public correspondence marine operators (MAROP) should be asked to attempt at least one contact. 3. When a vessel is overdue from a long sea voyage, SAR officials in other countries may be asked to assist through their RCCs, Navy, or other military channels. Other courses, such a AMVER, Naval Intelligence Operations Center, Lloyd's, or International Telecommunications Union (ITU), could be queried. United States Embassy or consular officials may also be contacted directly for assistance, with the Department of State an information addressee on messages. C. PRECOM for aircraft is usually begun by the FAA and conducted by the responsible ARTCC for IFR aircraft and by the responsible FSS for VFR aircraft. When an aircraft not on a flight plan is reported overdue, the RCC should begin an EXCOM immediately, while at the same
