AWARENESS STAGE

A period during which the SAR system becomes aware of an actual or potential incident.

PREPURGE PERIOD

A period on each start-up during which air is introduced into the combustion chamber and associated flue passages in volume and manner as to completely replace the air or fuel air-mixture contained therein prior to an attempt to initiate combustion.

TOTAL DRIFT ERROR

(De): sum of the individual drift errors from the time of a SAR incident until datum. Used when determining Total Probable Error (E).

SECURITY LEVEL 3

The level for which further specific protective security measures shall be maintained for a limited period of time when a security incident is probable or imminent, although it may not be possible to identify the specific target.

CORNER REFLECTOR

A radar reflector consisting of three mutually perpendicular flat reflecting surfaces designed to return incident electro- magnetic radiation toward its source. The reflector is used to render objects such as buoys and sailboats more conspicuous to radar observations. Since maximum effectiveness is obtained when the incident beam coincides with the axis of symmetry of the reflector, clusters of reflectors are sometimes used to insure that the object will be a good reflector in all directions. Also called TRIHEDRAL REFLECTOR.

POSTPURGE

A period after the fuel valves close during which the burner motor or fan continues to run, to supply air to the combustion chamber.

STIFFNESS

A stiff ship is one which have a short period of roll and therefore will roll uncomfortably

AMVER

Automated Mutual-Assistance Vessel Rescue System a worldwide voluntary system operated exclusively to support SAR and to make information available to all RCCs. It sponsored by the United States Coast Guard. It is a computer-based global ship reporting system used worldwide by search and rescue authorities to arrange for assistance to persons in distress at sea. With AMVER, rescue coordinators can identify participating ships in the area of distress and divert the best-suited ship or ships to respond. Participating in AMVER does not put ships under any additional obligation to assist in search and rescue efforts, beyond that which is required under international law.

INTERMITTENT FIRING

A method of firing by which fuel and air are introduced and burned in a furnace for a short period after which flow is stopped, this succession occurring in a sequence of frequent cycles.

ELASTICITY

The ability of a material to return to its original shape after any force, acting upon it, has been removed. properly heat-treated springs are good examples of elastic materials.
