Due to the increased range possible with VHF-FM radios transmitting from aircraft, low power should be used whenever possible.  Aircraft may not transmit on any VHF-FM maritime/government frequency when operating above 3000 feet above ground level (AGL) except in emergencies or when necessary to maintain essential communications.
 

 

 
 
Section C. Radio Procedures

 
Introduction
 This section describes the proper procedures to follow when transmitting information via radio communications.
 
C.1.  Before Transmitting
 Before transmitting:
. THINK – Plan what you are going to say.  Brevity is important.

. PREPARE – *
Know where you are.
*
 Know the frequency you are listening on.
*
Anticipate questions you may be asked to answer.

. LISTEN – Be sure that no one else is using the frequency.

 
C.2.  Aviation Phraseology
 There are certain procedures and phraseologies that are specific to air operations. Observers and air crew should practice aviation communications until they become second nature.  Practice not only improves communications, but also tends to overcome shyness or “mic fright”.
 
C.3.  Calls to a Coast Guard Unit
 The following are examples of typical radio calls from an aircraft: (in this example the aircraft registration is “N123AB”, and its FAA call sign <ID> is: “123AB”).  However, when contacting Coast Guard or Auxiliary facilities on VHF-FM, the Auxiliary aircraft should always identify itself as “Coast Guard AUXAIR 123AB” on the initial call of any group of calls.  The first call in any sequence of calls also uses the entire call sign, in this case “Coast Guard AUXAIR One Two Three Alpha Bravo”.  Subsequent calls in the sequence may use only the last three digits and/or letters, “Three Alpha Bravo”.
 
C.3.a.  Station Identifier
 The station identifier of the station called should be repeated 2 to 3 times on the initial call.
EXAMPLE:
“Coast Guard Sector Charleston, Coast Guard Sector Charleston,  this is Coast Guard AUXAIR One Two Three Alpha Bravo.  Over.”
 
C.3.b.  Successive Transmissions
 After communication is established, the call sign may be abbreviated to the name of the unit or the last three digits/letters of the call sign.
EXAMPLE:
“Charleston, this is Three Alpha Bravo, what is your message?  Over.”
 
C.3.c.  Tactical Call Signs
 When approved by an Air Station Commanding Officer (ASCO), tactical call signs may be used for a mission or missions when warranted by operational needs.  If so assigned, a record of the designated tactical calls will be kept by the air station and referenced to the actual facilities in use.
