COMMUNICATIONS Flashcards
What is CIC’s primary means of external communications?
Radiotelephone (R/T) {because of its convenience, speed, and simplicity}

Fleet Tactical (FLT TAC)
What communications are provided by Call-Bell systems
those between stations that normally dont need to exchange information continually
what is a general-purpose communications system used for transmitting orders and information between stations within a ship
multi-channel unit
What CIC/CDC radio circuit is used for maneuvering signals and urgent short tactical messages
task force/task group tactical (TF/TG tactical
What CIC/CDC radio circuit is used to coordinate aircraft and flight information within a controlled airspace
crosstell

a term for automatic tracking systems, which, in tracking data, use only iff
what is meant by the acronym MACCS
the marine air command and control system automated tactical data system
what are the two modes for operating the secure voice unit
plain voice and cipher
what is provided by the single audio system (SAS) remote channel
the ability for CIC/CDC watch standers to select, monitor, and transmit on a wide variety of external communication circuits
how does a power loss affect the operation of single audio system (SAS) remote channel
it will not function without power
what radiotelephone talker makes required reports to the beachmaster unit (BMU) during an amphibious ship-to-shore movement
the boat control bravo talker
