on flags with accuracy and speed comes only withpractice.There are many correct ways to bend on the flags.The best way is the method that enables YOU to dothe fastest and most accurate job possible. Adescription of one method of doing the job follows:To bend on, lead the uphaul part of the halyardunder the upper part of your right arm, with the snapon the end of the uphaul grasped firmly in your righthand. The ring on the end of the downhaul is in yourleft hand. (When standing by for a hoist to be calledout by the spotter, you can hook the snap on the uphaulinto the ring on the downhaul. This method preventsthe snap from accidentally being pulled out of yourhand and swinging out of reach.)As the first flag is called out by the spotter, hookthe halyard snap into the ring on the correct flag. Pullthe ring out of its slot with the snap and let go. Thengrasp the snap of the flag and pull it out. You are nowready to hook into the ring of the next flag. Continuethis process until the spotter calls out, “Going up.”Then hook the snap, which you are holding in yourright hand, into the ring on the downhaul, which youhave in your left hand. You are now ready to tell theperson on the uphaul to “Take it up.” The actualhoisting of a signal is generally a two-man job.Be sure there is sufficient slack in the halyard toprevent the snap from pulling out of your hand. In astrong wind, put the downhaul ring over a belaying pinto free your left hand, and use both hands to handle theflags. Never make fast a halyard in use. These halyardsmust be free for hoisting or lowering at an instant'snotice.NOTEAll Signalmen should know the locationof the emergency radar cutoff switches fortheir signal bridge. In the event of a lost hoist,this can prevent extensive equipment damge.When you call out to the person on the uphaul,“Take it up,” keep a slight strain on the halyard so thehoist goes almost straight up, not out with the wind.The person on the uphaul should haul away quicklyand speedily, hoisting the signal to the dip or close-upposition, as appropriate. PQS for flag bag operator iscontained in NAVEDTRA 43354B, PersonnelQualification Standards for Visual Communications.HAULING DOWN SIGNALSWhen a signal is hauled down, the person on theuphaul should keep a slight strain on the halyard asyou lower the hoist; otherwise, the hoist might fly outwith the wind and become fouled.Haul in quickly and evenly on the downhaul. Asthe ring on the downhaul comes to your hand, graspit. Then grasp the snap on the bottom flag, and unhookit from the halyard ring. Place the downhaul ring onthe belaying pin located in the fife rail on the flag bagfront. Keep hauling the rest of the hoist down to thedeck. As the topmost flag passes, unhook the snap endon the halyard, and hook it on the ring located on ornear the flag bag.As soon as the flags are on deck, the person on theuphaul should unsnap them one from another and handthem to you for restowing in the bag. As the flags arehanded to you, the name of each flag is called out toassist you in getting them stowed. When all flags arestowed and the halyards are made ready for the nexthoist, call out to the spotter, “Ready on thestarboard/port bag.”PARTS OF A FLAGHOIST MESSAGELEARNING OBJECTIVES: Identify andexplain the parts of a flaghoist message.A flaghoist signal or message consists of twoparts, heading and text. The heading may be specifiedby hoisting a visual call sign. Normally, a flaghoistsignal or message hoisted without call signs isaddressed to all units within visual contact or to thecommander of the unit.HEADINGThe heading of a flaghoist message is hoistedsuperior to the text. That is, it is displayed in a positionthat is read before the text of a message. So long as theheading appears before the text, it may be flown fromthe yardarm on outboard hoists (as in fig. 5-5) or at thetriatic stay or masthead.Modification of HeadingThe heading of a flag signal may be modified bythe use of the four substitutes as follows:FIRST SUB over the call sign of the originatorhoisted where best seen means "The originator of thissignal is .” Intervening ships relay this signal5-6
to the addressees or to the OTC if there are noaddressees.SECOND SUB in place of the address means “Forgeneral information, no specific address, no answerrequired.”THIRD SUB preceding the address means “Thissignal, in addition to being addressed to certain shipsfor action, is for general information and is to berelayed and answered as an all ships signal.”FOURTH SUB at the yardarm means ”Accompanyingsignals are taken from ATP 2, volume II” or nationalor regional defense organization publications.Construction of HeadingIn constructing flaghoist calls, numerals areexpressed by numeral pennants except when numeralflags are specifically indicated.The heading consists of the address. Ordinarily,only action addressees are indicated, but informationand exempted addressees may be included. Flag Wand the NEGAT pennant, respectively, are used forinformation and exempted addressees. The addressmay be omitted under the following situations:Signals to all ships from the OTC or senior officerpresent afloatBy ships addressing the OTC that are in directvisual communication with him/her and no relay isrequired and no confusion would resultBy ships or commands addressing emergencysignals to the OTCA tackline must often be used to separate call signs toavoid ambiguous combinations of flags in the heading.It will always be used to separate flag W from the callsign preceding and/or following it in the same hoist.Address designations used in flaghoist messagesare call signs, address groups, and sequence numbers.TEXTExample of a heading:ACTION—All shipsINFO—Main bodyEXEMPT—Amphibious forceHOIST—p2 TACK W TACK p3 NEGAT p3p2The text of flaghoist messages will consist of suchprescribed signals and plain language as may benecessary to convey the subject matter expressed bythe originator. Usually the message is made up ofsignals from the Allied Maritime Tactical Signal andManeuvering Book, ATP 1, volume II, or theInternational Code of Signals, Pub 102. Internationalsignaling is discussed in chapter 6.ALLIED MARITIME TACTICALSIGNAL AND MANEUVERING BOOKLEARNING OBJECTIVES: Explain theprocedure for the use of the Allied MaritimeTactical Signal and Maneuvering Book, ATP 1,volume II, including general procedures, listingchapters, the use of the supplementary tables,single flags and pennants, substitutes, andsupplementing signals. Describe proceduresfor encoding and decoding signals.ATP 1, volume II, is the origin of most tacticalcommunications between Allied naval units.The signal book consists of instructions, tabulatedsections of code, and special tables. The 34 chaptersof the signal book are constituted as follows:Chapter l—General Instructions for Use of theBookChapter 2—Single Flags and Special PennantsChapter 3—Emergency Alarm and Action SignalsChapters 4-9—Maneuvering Signals UsingPennantsChapters 10-34—Two-Letter and Number-LetterSignals, Special Tables (Operational andAdministrative), and Main Signal VocabularyThe overall security classification of the signalbook is NATO Restricted, but groups containedtherein are a simple unchanging code and have nosecurity. If the system of signaling is subject tointerception, only unclassified information should besent in the code. Unless specified otherwise, signalsfrom the signal book may be used with anycommunication media, including flashing light, voiceradio, and flaghoist.Chapter 1 is a must for all Signalmen. It containsthe general instructions for use of this publication.Take time to thoroughly study this chapter.Signals relating to certain important types ofactions are grouped in flag action tables. For instance,signals relating to ASW are located in one table. Thereare six flag action tables; each flag action table has a5-7
