CHAPTER 2 IHO S-52 4.0 Upgrade and Alarm Management



2.5



Reference Guide to PL 4.0 Changes



2.5.1 Detection and Notification of Navigation Hazard

The previous edition of the PL included the detection of rocks, wrecks and obstructions, with the safety contour

resulting in an alarm.

Rocks, wrecks and obstructions, as per the new PL standards, should result in an indication. This will reduce the

number of alarms but still ensures the mariner remains aware of the hazard.

Figure 2.1- A comparison of an ECDIS with PL 3.4 (on the left) showing an obstruction as an alarm,

with an ECDIS with PL 4.0 (on the right) showing only a warning



Detection and notification of navigation hazards in PL 4.0 has been designed to give the mariner the option to

choose the priority of the alert for navigational hazards, by viewing group category.

2.5.2 Standardised Automatic Update Symbols

Automatic update symbols have been standardised to help the mariner to identify and view where automatic

updates have been applied.

The new symbol will help the ECDIS operator to quickly identify features that have temporal attributes. E.g.

seasonal buoys, traffic separation schemes.

2.5.4 ECDIS Display Date Dependent Features

The ability to insert a date or date range to plan and check routes with date dependent features will allow the

mariner to view the conditions they will encounter on the date set. This allows inspection of the route for the

actual ETA at any given point.

2.5.6 Shallow Water Pattern

In PL 3.4, the shallow water pattern was optional. In the PL 4.0 it is mandatory. This is to help with visual detection

of shallow water in the night palette.

2.5. 7 SCAM IN

It is now mandatory for manufacturers to allow ECDIS operators to apply the SCAM IN (scale minimum) feature,

and also to be able to turn SCAM IN ON/OFF.

2.5.8 Hover-over Function

PL 4.0 has given guidance on the implementation of the optional 'hover-over' functions for a number of ENC

features. This attribute may not be available on all ENCs.

2.5.9 Anchorage Area, Fairways, Nautical Publications

Anchorage and fairway names will now appear when text is selected for viewing. This will help quickly

identification of locations and anchorages without the need to interrogate each area of the ENC.

2.5.10 ECDIS Legend

ECDIS legend will be made available at the position selected by the mariner. This will reduce the confusion about

the data that should be displayed when the own ship position is not on the ECDIS chart screen. Interaction is now

possible directly on the ENC display, with less confusion caused by menu structures.

ECDIS Chart 1 is a legend of symbols that may be used within the ENC. ECDIS Chart 1 can check for the correct

display of new symbols introduced in the PL 4.0.

ECDIS Chart 1 is installed on all type approved ECDIS systems.
