1127 - 03/17 - ECDIS Performance Check
The checks are designed to make mariners aware of any deficiencies with their system. Through feedback to the IHO it is also intended to build up a database of how different types of ECDIS display and handle data; this will in turn be passed to national hydrographic offices and the IMO.
