For the loaded chart, what happens when the Display Scale is enlarged by x2 or more than the Compilation scale of the ENC?
When the Display Scale of a chart is enlarged by a factor of 2 or more than the Compilation Scale of the Electronic Navigational Chart (ENC), several things can happen:
Loss of Detail: The chart may not display additional detail that is available at larger scales. Since the ENC is compiled at a specific scale, zooming in beyond that scale may result in a lack of information, as the data is not designed to provide more detail at that level.
Generalization: Features on the chart may appear more generalized or simplified. The ENC may not show all the features or may represent them in a less detailed manner when viewed at a scale larger than intended.
Potential for Misinterpretation: Users may misinterpret the information presented on the chart. Important navigational details may be overlooked or misrepresented due to the lack of detail at the enlarged scale.
Performance Issues: Depending on the software and hardware being used, zooming in significantly may lead to performance issues, such as lag or slow rendering of the chart.
Increased Risk: Navigating using a chart that is not at an appropriate scale can increase the risk of grounding or collisions, as critical navigational information may not be visible or accurately represented.
In summary, while it is technically possible to enlarge the Display Scale beyond the Compilation Scale, it is generally not advisable for safe navigation, as it can lead to a variety of issues related to detail, accuracy,
