Study Notes

ECDIS Performance Standards and Regulations

IMO Resolution A.817(19) was adopted on 23rd November 1995 to establish ECDIS Performance Standards.
SOLAS Regulation V/19 mandates that vessels on international routes must be equipped with ECDIS.

Electronic Navigational Charts

Vector charts are classified as electronic navigational charts (ENC).
Intelligent electronic charts are represented by vector charts (S-57).
IHO S-52 specifies chart content and display requirements for ECDIS.

ECDIS Advantages and Challenges

ECDIS offers the advantage of enhanced availability of electronic charts compared to paper charts.
Alarm deafness can result from excessive alarm frequency, potentially leading to dangerous situations.
Awareness of the limitations of ECDIS is crucial to avoid over-reliance, which can lead to navigation errors.

Electronic Chart Update and Compliance Dates

All ships are required to be fitted with ECDIS by 1 July 2018, regardless of size.
The 1998 IMO resolution MSC 86(70) allows the use of ECDIS in Raster Chart Display Systems (RCDS) mode.

Additional Features and Equipment

ECDIS devices can integrate with various equipment, displaying additional navigational information from vessel machinery.
All available digital publications, such as Nautical Almanac and Sailing Directions, can be accessed via ECDIS.
Display types on ECDIS include those that signal isolated dangers within safety contours.

Navigators must balance reliance on ECDIS with traditional navigational aids and situational awareness.
Statement declaring no need for lookouts is false; lookout duties remain essential for navigation safety.
Competence in planning and conducting passages using ECDIS is essential for officers-in-charge on vessels over 500 GRT.

Navigational Chart Types and Purposes

ENC is specifically designed for coastal navigation, enhancing inshore and offshore operations.
Raster charts are bitmap images derived from scanned paper charts.
Important file formats for raster charts include BMP, TIF, GIF, and JPG.

General Safety and Operational Awareness

Proper management of ECDIS is vital; improper use may result in ship groundings or collisions.
When using ECDIS, awareness and verification of passage plans must be maintained to ensure navigational safety.
