Comm 13-14: Communication networks Flashcards
What is Comms networks?
A chain of interconnected persons or operations enabling communication
For our purpose, the chain enables radio comms
One member of the chain is designated as the net control station
NCS controls the network. All other stations are member stations
Classes of Networks
Free network
Directed network
Methods of transmitting Data
Audio Teletype (morse) Facsimile Video/Computer Data Link

Flight information & advisory services Fss Fise fic Rco Drco Pal
Flight information center (FIC)
Various location across country
Provide preflight planning services (Wx, Notams, flight plans for filing)
En route planning services called flight information services enroute (FISE) (METAR, TAFs, SIGNMET, NOTAMS, RSC, CRFI, relay comms with ATC)
Flight service stations (FSS)
Provide airport advisory services (AAS) (Active rwy, W/V, air traffice advisory, wx conditions, etc
Monitor MF broadcasts
Manitoba FSS: Winnipeg, Brandon, Thompson, Churchill
Remote Communication Outlets (RCO)
Remote VHF transmitter/receivers
Established where difficult comms prevail
Enables FSS to provide remote aerodrome advisory service (RAAS)
Enable FIC to provide FISE
Dial-up remote communication outlet (DRCO)
Same as an RCO but have a dialup unit installed. The line is opened or activated by the aircraft in-flight or by the FIC
Key the mic 4 times
Peripheral Station (PAL)
Unstaffed VHF/UHF Tx/Rx established in remote locations to facilitate direct contact between aircraft and controlling agencies
Differ from RCO and DRCO in that the unit you are talking to is an air traffic controller vice FSS or FIC specialist
MACS
MACS – Military aeronautical comms system
