1.1 Electronic inclinometers are intended to support
the decision-making process on board in order to avoid dangerous situations
as well as assist in and facilitate maritime casualty investigations
by providing information about the roll period and the heel angle
of the ship.
1.2 Electronic inclinometers should, in a reliable
.1 determine the actual heel angle with the required
.2 determine the roll amplitude with the required
.3 determine the roll period with the required
.4 present the information on a bridge display;
.5 provide a standardized interface to instantaneous
heel angle to the voyage data recorder (VDR).
