System Electronic Navigational Chart (SENC means a database, in the manufacturer's internal ECDIS format, resulting from the lossless transformation of the entire ENC contents and its updates.

SENC stands for System Electronic Navigational Chart. When an ENC is loaded into the system, it becomes a SENC. ECDIS converts ENC data into its own internal SENC format for optimal chart image creation. SENC data can differ between manufacturers.

To correct a chart, look up the number of the chart in the index at the front of the NTM, by the chart number there will be a list of all the corrections that relate to that chart. Each correction is given a number to identify it. You then need to look up the correction to discover the details.

Basics of Electronic Navigational Charts. Electronic navigational charts are one of the two key elements of electronic navigation. An ECDIS functions as the hardware, while an ENC contains the dataset of relevant information for a voyage. Together, these two components create a powerful digital navigation solution.

Answer: The title tells us what the subject of the chart or graph is. The vertical axis tells us what is being measured. And the horizontal axis tells us the units of measurement represented.

An ECDIS should be capable of accepting and converting an ENC and its updates into a SENC. The ECDIS may also be capable of accepting a SENC resulting from conversion of ENC to SENC ashore, in ance with IHO TR 3.11footnote. This method of ENC supply is known as SENC delivery.

3 System Electronic Navigational Chart (SENC) means a database resulting from the transformation of the ENC by ECDIS for appropriate use, updates to the ENC by appropriate means and other data added by the mariner.

?Yes, paper charts are still available if you know where to look. FBOs and flight schools don't order many charts these days, but if you just need a current version of a local VFR sectional, IFR chart or Chart Supplement book, it's worth checking to see if they have it.

The Chart Supplement U.S. also provides a means for pilots to update visual charts between edition dates (The Chart Supplement U.S. is published every 56 days while Sectional Aeronautical and VFR Terminal Area Charts are generally revised every six months).
