JQR Notes Flashcards

1
Q

What are the three emergency phases?

A

Uncertainty - knowledge of a situation that requires more information; no movement of resources required.
Alert- Something may be wrong, but does not quite reach the threshold
Distress- Current or certain danger to life at sea

Q

When should a unit assume and designate an SMC?

A
  • Based on AORs
  • Delegate at the lowest level possible
  • District SMC required:
  • ELT, EPIRB, HF-DSC, Immarsat Alerts
  • Spans multiple Sectors
  • Conversation should be had when Sector exceeds 36 hours.

Q

What is SMC’s role when assisting DOD facilities with SAR?

A
  • SMC should be agreed upon between the DOD and the CG
  • Search efforts should not be delayed when determining SMC.

Q

How does Assistance Entry affect SAR?

A
  • Law of Sea Convention, which the U.S. is not privy to, states that it is the responsibility of mariners to provide assistance to those in peril, regardless of its occurrence in state waters.
  • Assistance efforts are consistent with Innocent Passage.
  • Must also balance country Sovereignty.

Q

What is optimal search effort?

A
  • Finding the search area to cover with the available efforts so that POS is maximized.
  • Increasing the probability of containment will decrease the probability of detection(reduction in coverage factor, etc).

Q

What is the importance and limitations of the DMB/SLBMB?

A
  • DMBs require aircraft or marine assets to relocate and take away from the search efforts
  • SLDMBs are satellite-based and built toward EDS products.

Q

What is the total water current?

A
  • Vector sum of all currents affecting the search object.
  • Usually obtained from one or more DMBs

Q

What is Leeway?

A
  • Movement through the water caused by winds.
  • Greater sail areas contribute to this force.

Q

What is the significance of search endurance?

A
  • 85 percent of on scene endurance, 15 percent for identifying objects.
  • Based on assets’ ability to transit to and from its place of origin.

Q

What is the significance of SRU ground speed?

A
  • Increased speed may affect endurance and negatively affect POD because of decreasing sweep width.

Q

What is the significance of Track Spacing?

A
  • Distance between two parallel legs.
  • Used in the determination of the Coverage factor.
17
Q

What is sweep width?

A
  • The probability of detecting an object outside of the swath is equal to the probability of missing the search object inside of the swath.
18
Q

What is the coverage factor?

A
  • A measure of the thoroughness or how well an area is searched.
19
Q

What are the different types of search patterns?

A
  • Trackline - Known intended route.
  • Parallel - Larger, level search areas. Approximate initial position.
  • Creeping line - Cover one end of the search pattern or to adjust for sun glare.
  • Square - Used to search small area when some doubt exists regarding the position
  • Secttor - Known datum. saturate the area around the datum
    _ Contour - Mountainous and hilly terrain.
  • Homing
  • Cross over the barrier
20
Q

What is the probability of detection?

A
  • Probability that the search object will be detected.
21
Q

What is the Probability of Containment?

A
  • Probability the search object will be in the search area.
22
Q

What is probability of success?

A
  • Probability of finding the search object based on POC and POD.
23
Q

How does selection criteria affect search pattern determination?

A
  • Search patterns depend on accuracy of datum, sear area size, number and capabilities of SRUs, environmental conditions, size of search target, and type of survivor aids.
24
Q

What is major axis selection criteria?

A
  • Parallel pattern are aligned with the major axis, its the opposite for creeping patterns.
25
Q

What is the Commence search point?

A
  • Ensures SRUs can effectively plan their search pattern execution.
  • Allows for SRU deconfliction.
26
Q

What is the altitude selection critiria?

A
  • Ignore sweep witdth differences of less than 10%
  • Separate aircraft by 500ft
  • no more than 500ft below the cloud level.
27
Q

What factors affect sweep width?

A
  • Search Object Characteristics
  • Meteorological visibility
  • Terrain/Sea conditions
  • Cloud Cover
  • Search Altitudes
  • Search Speed
28
Q

What are the trade-offs between POC POD?

A
  • High POC can lead to a large, unsearchable area.
  • High POD can lead to reduced search endurance.
29
Q

What are the advantages and limitations of SAROPS?

A
  • Multiple Search objects
  • Seven scenario types
  • Independant drift trajectory
  • User specified on scene conditions
  • Focus on single or multiple objects
  • Only as good as the inputs.
  • Manual manipulation my be required
  • Operator has to make significant assumptions
  • Network instability.
30
Q

What are the benefits of drifting multiple search objects?

A
  • Can utilize the drift to imagine all possibilities of a distress situation.
  • Allows “optimization” on one or all of the search objects for a given SRU
31
Q

Discuss weighing search objects.

A
  • Objects can be weighed based on the probability that they will occur in a given scenario.
  • Unless you have cause, let SAR ops weigh them manually.
32
Q

What is the Monte Carlo Drift method?

A
  • Drifting multiple particles based on EDS or manual environmental data.
