10.9 CPA and TCPA Notifications
The CPA (Closest Point of Approach) and TCPA notifications alert you when an AIS-
equipped vessel is within the preset distance (range) or time from your vessel. These
notifications can be used to help avoid dangerous situations.
1. From the [Home] screen, tap [Settings] => [Notifications] => [AIS].
2. Tap the [CPA] toggle box to show [ON]. The settings for this notification become
active.
3. Drag the slider to set the [CPA], or tap the keyboard icon to enter a value.
4. Tap the [TCPA] toggle box to show [ON]. The settings for this notification become
active.
5. Drag the slider to set the [TCPA], or tap the keyboard icon to enter a value.
6. Close the menu.
When a target has a lower CPA or TCPA than the notification setting, the notification
is triggered, releasing an audible beep and an on-screen notification. Tap the indica-
tion at the top of the screen to silence the audible beep. Take the necessary precau-
tions to avoid a collision.
The notification remains until the target is no longer within the notification setting
threshold, or the CPA/TCPA notification is disabled.
