3、wo-way voicecommunications cannot be established during ground emergen-cies.Ground signals are limited to land-based ones that do notrequire special equipment.Flare,light,panel,and maritimesignals are specifically excluded.1.2 The signals are divided into two categories:those usedby persons on the g

6、d in this practice have been overcome by technologydevelopment,situations still arise where voice communicationscannot be established between aircraft and persons on theground during emergencies.This is particularly true of personsin distress,who typically have no communications equipment.These sign

8、ent such as flares or colored panels.Othersignaling systems are described in the National Search andRescue(SAR)Manual.33.3 The signals are also useful in situations where eithercomplete or partial voice communications exist.Where onlypartial capabilities exist,for example,a ground unit withreceive-o

9、nly capability,the aircrew can transmit voice and theground crew can respond with the appropriate signal.3.3.1 The signals described in Section 4,by their nature,arenot intended for real-time communications with aircraft.Theycan be left unattended as messages for aircrews.Persons on theground(SAR or

10、 otherwise)can make a signal and continue onwithout contact with the aircraft.The SAR personnel shouldkeep this in mind when encountering the signals of Fig.1.3.4 Search and rescue agencies utilizing this practice shoulddisseminate these signals to the public as part of their preven-tative search an

12、 International Civil Aviation.As defined inAnnex 12 to the Convention(see 2.1),these signals are dividedinto those for use by SAR personnel and those for use bypersons in distress.Several of the signals have only beenadopted by certain countries.4.1.2 Since the signals are useful regardless of the u

13、serssituation or location,this practice includes all of them withoutlimitation.While there may be potential for this to causeconfusion for aircrews seeing the signals,this would be atemporary condition and the aircrews response should not bedependent on the users status.The benefits of unlimited use
