Trigger Type is Direction Alert
A Direction Alert is used to indicate that a heading or wind direction has changed from the reference
direction more than a programmable amount. For example, once a heading has been established, an
alert can be generated if the heading changes more than a specified amount. Direction Alerts may
also be set for wind direction. The reference direction can be selected from the current direction
(heading or wind direction) or it can be manually entered. Figure 293 shows a Direction Alert and
associated parameters.
