OPERATIONAL PARAMETERS SUCH AS SHIP'S SPEED,
STOPPING DISTANCE AND GENERAL ABILITY TO MANOEUVRE,
SEE CHART DANGERS. IN ADDITION TO THE OWN SHIP BASED
SAFETY CHECKING THE OPERATOR SHOULD REVIEW THE
DANGERS LIST PROVIDED ON THE DANGERS TAB OF THE
MONITOR ROUTE MENU WHENEVER A NEW ROUTE IS LOADED,
AND PERIODICALLY DURING THE ROUTE WHEN PROGRESSING
TO NEW LEGS, SEE MONITOR ROUTE - DANGERS. THE ROUTE-
BASED REGION CHECKED USES THE XTD ALERT LIMIT WHICH
IS TYPICALLY MUCH WIDER THAN THE OWNSHIP SAFETY
REGION, AND THEREFORE CAN INDICATE THE AVAILABLE
CORRIDOR FOR SAFE DEVIATION FROM THE ROUTE ON EITHER
SIDE OF THE TRACK LINE.
IT IS PARTICULARLY IMPORTANT THAT THE OPERATOR BE
AWARE THAT:
1. THE OWNSHIP BASED SAFETY CHECKING IS THE ONLY
SAFETY CHECKING PROVIDED WHEN MAKING A DEVIATION
ON A TEMPORARY ROUTE. THE TEMP ROUTE DOES NOT
APPLY A SAFETY CHECKING REGION BASED ON THE XTD
LIMIT AS THE SAVED/NAMED ROUTE DOES. THE DANGERS
LIST PROVIDED ON THE ROUTE MONITOR 'DANGERS' TAB
ARE FOR THE PERMANENT ROUTE ONLY.
2. SAFETY CHECKING IS DONE PERIODICALLY, WITH AS MUCH
AS 30 SECONDS BETWEEN SEARCHES. THE OPERATOR
SHOULD THEREFORE BE AWARE THAT THERE MIGHT BE A
SLIGHT DELAY IN UPDATING THE LIST OF CHART DANGERS
TO REFLECT THE CURRENT CONDITIONS.
3. SAFETY CHECKING WILL NOT BE APPLIED TO AN AREA OF
AIO DATA (FOR INFORMATION REFER TO AIO DATA IN PICK
REPORT). NORMAL SAFETY CHECKING WILL CONTINUE TO
APPLY TO THE ENC CHARTS THAT THE AIO IS ASSOCIATED
WITH.
