Datum
Most probable location of a search object corrected for movement over time
Leeeway
Movement of a search object through the water caused by winds blowing against the exposed surface of the search object
Security
General information broadcast to public.. log adrift in channel
Expanding square
Last know position of a search object has a high degree of accuracy, the search area is small concentrated search is desirable
Second unit starts 45degrees right
Vs
Sector search
Datum is established with a high degree of confidence but the search object is difficult to detect
Parallel patterns
There is equal probability that the search object could be anywhere in the search area
Creep line
Probable location of search object has been determined to be more likely at one end of search area than other
PAN-PAN
Urgency signal
Urgent message to transmit concerning the safety of a ship, aircraft, vehicle, or person
SECURITÉ
Message concerning the safety of navigation or important weather warning
