Appendix 10: Admiralty
Information Overlay

AP10.1 Introduction

The Admiralty Information Overlay (AIO) is a digital data set that is designed to be displayed over ENCs in ECDIS
to provide additional information to the navigator.
The AIO contains all Admiralty Temporary & Preliminary Notices to Mariners (hereafter referred to as T&P NMs)
and provides additional preliminary information that is specific to ENCs, such as reported navigational hazards that
have been incorporated on paper charts but have not yet been included in ENCs.
The AIO gives seafarers an easy way to view the information they need, in addition to the standard chart, to navigate
safely and compliantly. The AIO makes passage planning simpler and safer by clearly showing where important
Temporary or Preliminary changes may impact a voyage. It also gives seafarers the same consistent picture of the
maritime environment on their ECDIS as they have always had with the Admiralty paper chart.
The AIO includes all Admiralty T&P NMs in force worldwide and additional information that relates specifically to
ENCs, published as ENC Preliminary NMs (EP NMs).
