WEEK 10 LEC NAV 6

Summary

In this week 10 lecture, Second Mate Evaristo Feliciano instructs on setting alarms for navigation safety using the Electronic Chart Display and Information System (ECDIS). He explains the importance of monitoring alarms for potential dangers and setting safety parameters such as depth and course limits. The lecture covers the activation of safety frames, contour alerts, and area limits to prevent accidents and ensure safe navigation.

Q & A

What is the main topic of the lecture?

The main topic of the lecture is discussing the navigation alarms and safety settings on an Electronic Chart Display and Information System (ECDIS) for NAB 6 midterm.

Who is the instructor of the lecture?

The instructor of the lecture is Second Mate Evaristo Feliciano.

What is the purpose of setting alarms in the ECDIS?

The purpose of setting alarms in the ECDIS is to provide warnings when the vessel is approaching an area of danger or concern to prevent accidents such as grounding or collision with the seabed.

How do you access the monitoring panel in ECDIS?

You access the monitoring panel by selecting the appropriate line of the task list menu on the control panel and activating the monitoring option.

What are the different pages of the monitoring panel?

The monitoring panel has three pages: the root monitoring page, the safety alarm page, and the navigational alarms page.

What is the significance of the 'End of Route' alarm setting?

The 'End of Route' alarm setting is significant because it activates an alarm when the vessel passes the end of the planned route, indicating that the vessel has deviated from the planned course.

What does the 'Out of Schedule' alarm indicate?

The 'Out of Schedule' alarm indicates whether the vessel is ahead or behind schedule. It is set to activate a certain number of minutes before or after a predetermined time.

What is the purpose of the 'Waypoint Approach' alarm setting?

The 'Waypoint Approach' alarm setting is to alert the crew a certain number of minutes before approaching a waypoint, preparing them for the alteration of the waypoint.

What does the 'Out Leg Off Leg' alarm setting refer to?

The 'Out Leg Off Leg' alarm setting refers to the steering course deviation. It alerts the crew if the vessel deviates more than a set number of degrees from the intended course.

What is the safety frame group in ECDIS?

The safety frame group in ECDIS is a setting that defines a safety margin around the vessel's planned route to generate anti-grounding alarms, area alerts, and navigational alarms.

Why is it important to set safety parameters in ECDIS?

Setting safety parameters in ECDIS is important to ensure the vessel stays within safe navigational limits, such as avoiding shallow waters or designated no-go areas.

What is the role of the 'Safety Contour' setting?

The 'Safety Contour' setting defines the minimum depth a vessel should maintain to avoid running aground. It helps in creating a no-go area based on water depth.

What is the difference between 'Shallow Contour' and 'Deep Contour'?

The 'Shallow Contour' defines areas of water that are shallower than a set depth and are considered dangerous. The 'Deep Contour' defines areas deeper than a set depth, usually not a concern for navigational safety.

What is the 'Area Limits' setting used for in ECDIS?

The 'Area Limits' setting is used to define areas that the vessel should avoid or be alerted when entering, such as traffic separation zones, restricted areas, or fishing grounds.

What is the significance of the 'Anchor Watch' alarm setting?

The 'Anchor Watch' alarm setting is used when the vessel is at anchor to alert the crew if the vessel starts dragging its anchor.

What is the 'Off Chart Alarm' and when is it activated?

The 'Off Chart Alarm' is activated when the vessel navigates outside the charted area, indicating that the vessel has ventured beyond the mapped region.
