I cannot comment on that training aid, but running an AIS
display alongside will help you to understand what you are seeing, and will enable you to make much better use of the radar
. I personally prefer the software
and displayed on a laptop
, primarily because of the ability to display CPA data, and the audio warning of contacts on a dangerously close CPA.
These are not an either/or tool, but rather a complementary pairing, and using the AIS
to identify what it is you are seeing, will help to speed the development of these skills.
