SNFO/SWSO VOICE COMMUNICATIONS

CHAPTER ONE

Using only the last two digits (minutes) when expressing time. When two numbers are

used, the current hour is understood to be the time being referenced, and the two stated digits

signify the minutes.

Example

SNFO/SWSO:

"Center, KATT 815 estimating Semmes TACAN

at time FOUR THREE."

"Four Three" is understood to mean 43 minutes past the current hour. If the call was made

at 0935 on your watch, KATT 815 will arrive at Semmes at 0943.

Current time in use at a station may be stated to the nearest quarter minute in order to

facilitate time checks or to set their clocks. Standard phrases include: straight up (00 sec), one

quarter (15 sec), one half (30 sec), and three quarters (45 sec). The only reference to this type of

time reference will be during shipboard operations.

Example

CONTROLLER:

"KATT 805, Approach, hold as published, expect

further clearance at time 0945, time now 0929 and

one quarter."
