A Pilot's Observations

11 Aug 2011 Resource

The problems that I have encountered tend to be in two specific areas.

  1. Installation and Initiation - Several units that I have observed have marginal installations (poor antenna placement, which compromises the range and azimuth of reception).  I have also noted, but with less frequency now, improper static data (e.g. ship dimensions and antenna location)  This can be a minor error or more significant which can lead to target separation on an ARPA display, even at a close range.

     
  2. Training - It appears that there is little to no training in the operation of AIS units, regardless of whether they are MKDs or fully integrated into an ECDIS or ARPA.  Mariners are self taught.  There are limitations to the AIS tool and these need to be stressed along with its capabilities.
