D Differences Between Raster Chart Display System (RCDS) and ECDIS

26 ECDIS may be operated in one of the two modes:

  • .1 the ECDIS mode when ENCs are used; and

  • .2 the RCDS mode when ENCs are not available and RNCs are used instead.

Although in recent years ENC coverage has increased rapidly there could be some areas for which suitably detailed ENCs may not have been issued.

27 The RCDS mode does not have the full functionality of ECDIS and can only be used together with an appropriate portfolio of up-to-date paper charts. Limitations of the RCDS mode is set out in appendix 2.
