Can the navigator modify the cross track distance (XTD) for each route leg on an ECDIS?

Can the navigator modify the cross track distance (XTD) for each route leg on an ECDIS?

• A. No, it is fixed for all route legs
• B. Yes, it can be modified for each route leg
• C. Only in emergency situations
• D. Only for the final leg of the route

Answer: (B)

The ability of a navigator to modify the cross track distance (XTD) for each route leg on an ECDIS reflects the software's flexibility and the need for precise navigation. In practice, navigators can adjust the XTD settings based on specific navigational needs, environmental conditions, or to optimize the vessel's course. This customization allows for better route planning and adherence to safety parameters, making it easier to navigate through constrained or hazardous waters where adjusting the XTD may be necessary to avoid dangers or to follow specific traffic separation schemes. Therefore, stating that the navigator can modify the XTD for each route leg emphasizes the adaptability of the ECDIS system in supporting navigational decisions, enhancing safety, and accommodating the variances in route planning.
