31
Q

WHAT IS TRACK SPACING (S)?

A

THE DISTANCE BETWEEN ADJACENT SEARCH LEGS.

32
Q

WHAT ARE THE SEARCH LEGS IN A (PS) SEARCH PATTERN PARALELL TO?

A

THE MAJOR AXIS OR LONG SIDE OF THE SEARCH PATTERN.

33
Q

WHERE IS THE COMMENCE SEARCH POINT (CSP) ON A PARALLEL AND CREEPING SEARCH PATTERN?

A

1/2 TRACK SPACE INSIDE THE SEARCH AREA.

34
Q

WHY IS THE CSP 1/2 TRACK SPACE IN THE ABOVE QUESTION?

A

TO PREVENT EXCESSIVE COVERAGE AND TO GIVE A MARGIN OF SAFETY.

35
Q

WHEN IS A CREEPING SEARCH PATTERN. USED?

A

WHEN THE SEARCH AREA IS NARROW AND AN IMMEDIATE SEARCH IS DESIRED AT ONE END.

36
Q

WHAT IS CREEP?

A

THE GENERAL DIRECTION AN SRU MOVES THROUGH A RECTANGULAR SEARCH AREA.
NORMALLY THE SAME DIRECTION AS THE CROSS LEGS.

37
Q

WHAT IS TSR?

A

TRACKLINE SINGLE-UNIT RETURN.

38
Q

WHEN IS A TRACKLINE SEARCH USED?

A

WHEN YOU HAVE A VESSEL OR PERSON MISSING AND THE INTENDED ROUTE IS THE ONLY SEARCH LEAD.

39
Q

WHERE IS CSP IN A TRACKLINE SEARCH?

A

1/2 TRACKSPACING FROM THE TRACKLINE.

40
Q

WHAT ARE SOME OF THE VARIOUS METHODS OF DESCRIBING SEARCH AREAS?

A

CORNER POINT, BOUNDRY, TRACKLINE, CENTER POINT, GRID, AND GEOREF.

41
Q

WHAT DOES PROBABILITY OF SUCCESS (POS) GIVE?

A

A MEASUREMENT OF SEARCH EFFECTIVENESS.

42
Q

WHAT IS POS A PRODUCT OF?

A

PROBABILITY OF AREA AND PROBABILITY OF DETECTION. POS - POA X POD.

43
Q

WHAT THREE BASIC SEARCH FACTORS ARE USED TO COMPUTE TRACK SPACING?

A

PROBABILITY OF DETECTION (P), COVERAGE (C), AND SWEEP WIDTH (S).

44
Q

DEFINE COVERAGE FACTOR (C).

A

THE MEASURE OF SEARCH QUALITY GIVEN IN TENTHS. THE HIGHER THE COVERAGE FACTOR, THE MORE THOROUGH COVERAGE OF THE SEARCH AREA.

45
Q

WHAT IS SWEEP WIDTH (W)?

A

A MEASURE OF DETECTION CAPABILITY DUE TO TARGET CHARACTERISTICS, WEATHER AND OTHER LIMITATIONS EXPRESSED IN NAUTICAL MILES AND/OR TENTHS OF NAUTICAL MILES,

46
Q

WHAT SHOULD SWEEP WIDTH NEVER EXCEED?

A

TWICE THE MAXIMUM DETECTION RANGE.

47
Q

WHAT IS THE FORMULA FOR DETERMINING TRACK SPACING (S)?

A

S = W/C.

48
Q

WHAT DOES IT MEAN WHEN A SEARCH IS UNRESOLVED?

A

THERE IS INSUFFICIENT INFORMATION TO EITHER CLOSE OR SUSPEND A CASE.

49
Q

WHAT IS REQUIRED FOR UNRESOLVED RED OR ORANGE FLARE SIGHTINGS?

A

FIRST LIGHT SEARCHES.

50
Q

THE COAST GUARD ENDORSES THE 406 EPIRB. WHAT SHOULD BE THE SAR RESPONSE TO ONE OF THESE?

A

AS IF IT WERE A MAYDAY,

51
Q

WHAT IS THE DIFFERENCE BETWEEN A HOAX AND A FALSE ALARM?

A

A HOAX IS WHERE INFORMATION IS CONVEYED WITH THE INTENT TO DECEIVE. A FALSE ALARM IS WHERE THE DISTRESSED UNIT IS NOT ACTUALLY IN DISTRESS DUE TO MISJUDGEMENT OR BY INADVERTENTLY ACTIVATING A DISTRESS BEACON,

52
Q

WHO CAN CLOSE A HOAX CASE ONCE THE SOURCE IS CONFIRMED?

A

SMC,

53
Q

WHAT IS THE KEY WORD FOR UNCERTAINTY PHASE?

A

DOUBT.

WHAT IS THE KEY WORD FOR ALERT PHASE?

A

APPREHENSION.

55
Q

WHAT IS THE KEY WORD FOR DISTRESS PHASE?

A

GRAVE DANGER.

56
Q

WHAT IS SAFE HAVEN?

A

A PLACE THAT CAN ACCOMODATE SAFE MOORING AND HAS AN AVAILABLE MEANS OF COMMUNICATIONS, NORMALLY A TELEPHONE.

Q

WHAT DOES MARB STAND FOR?

A

MARINE ASSISTANCE REQUEST BROADCAST.

59
Q

IF SOMEONE INTERFERES WITH GOVERNMENT COMMUNICATIONS, WHAT COMMAND SHOULD BE ISSUED?

A

8 DEGREES

62
Q

WHAT DOES A FLARE ANGLE OF MORE THAN 8 DEGREES MEAN?

A

THE DISTANCE OF THE FLARE FROM THE OBSERVER IS LESS THAN 1.1 NAUTICAL MILE.

63
Q

WHEN DO YOU HAVE AN OSC?

A

WHEN THERE ARE TWO OR MORE UNITS SEARCHING.

64
Q

HOW MANY TIMES IS “MAYDAY” REPEATED?

A

THREE TIMES.

65
Q

ONCE A PERSON MEETS OR EXCEEDS THE GIVEN FATIGUE STANDARDS, HOW MUCH RECOVERY TIME SHOULD THEY BE GIVEN?

A

10 HOURS MINIMUM!

66
Q

WHO MAY WAIVE FATIGUE STANDARDS FOR URGENT SAR?

A

THE GROUP COMMANDER.

67
Q

WHEN ARE OPS NORMAL REPORTS GIVEN FROM SINGLE ENGINE AIRCRAFT?

A

EVERY 15 MINUTES.

68
Q

WHEN ARE OPS NORMAL REPORTS GIVEN FROM MULTIPLE ENGINE AIRCRAFT?

A

EVERY 30 MINUTES.

69
Q

WHAT ARE THE TWO TYPES OF MESSAGES?

A

SITREPS AND SEARCH ACTION PLANS.

70
Q

WHO COMPILES SITREPS?

A

THE OSC.

71
Q

WHAT ARE THE FIVE PARTS OF A SITREP?

A

IDENTIFICATION, SITUATION, ACTION TAKEN, FUTURE PLANS, AND CASE STATUS.

72
Q

WHEN ARE SITREPS SENT BY THE OSC?

A

UPON ARRIVAL ON-SCENE, WHEN TIME CRITICAL INFORMATION NEEDS TO BE PASSED, AND THEN NO LESS OFTEN THAN EVERY 4 HOURS.
