C.6.b.  Altitudes
 Altitudes are reported with separate digits for the thousands, plus hundreds, if appropriate.
EXAMPLE:
4500 ft – “four thousand five hundred”; or, 10,000 ft – “one zero thousand”
 
C.6.c.  Heading or Direction
 Three digits are used when giving a heading or direction.
EXAMPLE:
050 degrees – “heading zero five zero”; or 000 degrees – “due North heading zero zero zero”
 
C.6.d.  Speed
 Speed is given in knots.
EXAMPLE:
120 knots – “one two zero knots”
 
C.6.e.  Transfers Between Air Traffic Controllers
 When the aircraft is “handed off” from one air traffic controller to another, always include altitude when making the initial contact.
EXAMPLE:
“Mobile Approach, this is Coast Guard AUXAIR Cessna One Two Three Alpha Bravo at seven thousand.”
 
C.6.f.  Short Counts
 When a short transmission is required for receiver tuning or direction finding, a “short count” is employed.  This consists of counting from one to five and back.  The transmission should not exceed 10 seconds.
 
C.6.g.  Long Counts
 When a longer transmission is required, a “long count” is employed.  This consists of counting from one to nine and back.
 

 
C.7.  Good Communication Practice
 The following good communication practices are intended to supplement the specific radio procedures provided above.
 
C.7.a.  Listening
 Listening is key to successful communications.  Ensure the radio volume and squelch are properly set.  Ensure one crewmember is tasked with continually listening for communications and not only when “ops normal” messages are due.
 
C.7.b.  Microphone Operation
 The microphone button should be used properly.  Press to talk and hold the microphone key for a half-second before speaking.  The microphone should be spoken into directly at a distance of about 1 inch from the lips.  Engine and wind noise may cover most of the message if proper technique is not used.  Shouting into the microphone will result in distortion of the signal.
 
C.7.c.  Difficulty Maintaining Guard
 When working a case with other assets and having difficulty maintaining guard because of radio reception, it may be possible to temporarily use other units as relays until better communications can be established.
 

 
 
Section D. Mission Communications

 
Introduction
 Mission communications consist of an orderly sequence of communications between an Auxiliary aircraft and the Coast Guard unit that is holding the aircraft  radio guard.  These communications are normally planned and expected, but may occur spontaneously as an Auxiliary aircraft moves through the AOR of a Coast Guard unit.
