11、 International Civil Aviation OrganizationLicensed by Information Handling ServicesFOREWORD 1. General 1.1 The essence of successful search and rescue lies in the speed with which it can be set up and carried out and the accuracy with which the search area can be defined. This is so because it must

12、be presumed that in each incident there are survivors who need help and whose chances of survival diminish with every passing minute. 1.2 The COSPAS-SARSAP system, which has been developed by Canada, France, the Union of Soviet Socialist Republics and the United States, introduces space technology t

13、o assist in expediting search and rescue and in defining the search area. Experience gained from the COSPAS-SARSAT project has demonstrated significant advantages to be gained by satellite-aided alerting. 1.3 The purpose of this circular is: a) to acquaint personnel responsible for search and rescue

14、 as well as air traffic services personnel, communications specialists and pilots, with the status of the COSPAS-SASAT system and how it assists search and rescue; and b) to inform States which may be interested in taking advantage of the COSPAS-SARSAT system of the points of contact, levels of par

15、ticipation, and likely costs. Although this circular focuses on aeronautical applications of the COSPAS-SARSAT system; it has broader humanitarian applications which include maritime and terrestrial search and rescue. 1.4 The term “emergency transmitters“ when used in t.his circular is a generic ter

16、m which encompasses emergency location beacons - aircraft (ELBA), survival radio equipment which emits a distinctive tone, emergency position indicating radio beacons (EPIRB) and emergency locator transmitters (ELT). 2. Background 2.1 At the 23rd Session of the ICA0 Assembly in 1980, the Technical C

17、ommission took note of a report submitted by the Delegation of Canada on experimental work related to search and rescue satellite-aided tracking (SARSAT). Since that time, the develop- ment of the COSPAS-SASAT system has been monitored and reported on in annual reports of the Council, articles in th

19、98L i02 ii) ICAO Circular 185 2.2 In November 1985, the Secretariat prepared a summary report on the COSPAS- SARSAT system. The Air Xavigation Gmmission, after reviewing this report, agreed that: a) appropriate information concerning COSPAS-SARSAT be prepared in the form of an ICAO circular: States

20、not: yet participating in the COSPAS-SARSAT programme be invited to reconsider such participation in accordance with the Councils request of 14 December 1983; all States be invited to take action aimed at reducing the number of false alarms on 121.5/243.0 MHz caused by inadvertent activation of emer

21、gency transmitters and eliminating misuse of those frequencies for unauthorized purposes, and to continue their efforts to eliminate unauthorized transmissions in the band 406.0 “z and 406.1 MHz; and an air navigation study group be established to assist the Secretariat in examining the various aspe

22、cts relating to the use of the COSPAS- SARSAT system and developing specific proposals for action. 2.3 The decisions in b) and c above were reflected in State Letter AN 15/12-86/50 dated 7 May 1986 and the air navigation study group mentioned in d) began wrk in June 1986.

BACKGROUND .1 CONVENTIONAL ALERTING METHODS 1.1.1 General 1.1.1.1 The success of a search and rescue operation depends, to a large degree, OR the prompt receipt by the rescue Co-ordinati

40、on centre (RCC) of information needed for an evaluation of the situation and a decision on the best course of action. Only then can activation of search and rescue facilities be assured, making it possible to: a) locate, reach, sustain and rescue survivors in the shortest possible time ; b) facilita

41、te self-help by survivors while they are still capable of doing so. Experience has shown that the chances of survival after an accident decrease significantly during the first 24 hours for injured persons and after the first three days for uninjured persons. Experience has also shown that, because o

42、f the shock effect following an accident, uninjured and able-bodied persons are often unable to accomplish simple tasks in a logical manner and thus may hinder, delay or even prevent their own rescue. 1.1.1.2 usually receives notification that an aircraft is, or is considered to be, in a state of em

43、ergency from the flight information centre (FIC) or area control centre (ACC) with which it is associated. Normally, this notification is determined in relation to an . aircraft flight plan, transmissions made by the distressed aircraft, reports by other aircraft (visual observations, transmissions

44、from emergency transmitters), loss of radar contact, or from other sources. The state of emergency is indicated by: Although search and rescue organizations have different strucqures, an RCC 1) an uncertainty phase; 2) an alert phase; or 3) a distress phase. 1.1.2 Notification based on flight plan I

45、 1.2.1 In respect of an aircraft for which a flight plan has been filed, an uncertainty phase is declared when: a) no communication has been received within 30 minutes after the time it should have been received, or from the time a first unsuccessful attempt was made to establish communications wit

46、h the aircraft; or b) the aircraft fails to arrive within 30 minutes of the estimated time of arrival (ETA). 1 COPYRIGHT International Civil Aviation OrganizationLicensed by Information Handling ServicesICAO CIRCULAR*LC * 484141b 00OZ88 Ob7 2 ICAO Circular 185 1.1.2.2 When notification is baser3 on
