AvNav Settings Page

The Settings Page

From the main page you get here using the button.

Buttons

Icon	Name	Function
	SettingsOK	accept changes and go back
	SettingsDefaults	reset all settings to their default values
	SettingsLayout	start of the layout editor
	SettingsAddons	go to user app configuration
	SettingsSave (since 20220225)	Save the current settings to the server
	SettingsLoad (since 20220225)	load a settings file from the server (you will be able to select from a list)
	MOB	man over board (see main page)
	Cancel	discard changes and go back

You can set many parameters affecting your display. All those settings are stored in the current browser (associated with the URL you used to open AvNav). They are not stored on the server!

For most values there is a separate reset button. Globally you can reset to defaults using the button. A confirmation dialog is displayed when leaving the page without saving.

Most of the settings should be self explanatory. Some more sophisticated ones are described below.

Category	Value	Description	Default
Buttons	auto hide buttons on NavPage	Hide the buttons on the navigation page after a timeout (can be configured). Clicking on the right border will bring the buttons back.	off
Buttons	auto hide buttons on Dashboard Pages	Hide the buttons on the navigation page after a timeout (can be configured). Clicking on the right border will bring the buttons back.	off
Buttons	time(s) to hide buttons on enabled pages	Time (in seconds) until the buttons are hidden on the pages where this is configured.	30
Buttons	show shade when buttons hidden	Show a shadow area on the right side when the buttons are invisible. You need to click on this are to bring the buttons back.	on
Layout	red icons in title	show small red icons in the page upper right corner for anchor watch and disconnected mode	on
Layout	title icons on dashboard page	also show the red icons for anchor watch and disconnected on dashboard pages	on
Layout	start with last split mode	if enabled the WebApp will start in the same mode (split/unsplit) like it was left (since 20240616)	off
Navigation	boat direction	Define which NMEA value will be used to draw the boat symbol orientation.: COG, HDT, HDM. If you configure HDT or HDM and this value is not being received it will fall back to COG. The course vector will be determined by COG in any case. Since 20220421: If HDT or HDM are used a boat symbol will be drawn instead of the default arrow being used for COG. Can be customized by user icons .	COG
Navigation	add dashed vector for hdt/hdm	Show an additional dashed course vector if you configured HDM or HDT for the boat orientation.	on
Navigation	Rotation Tolerance	If you configured "course up" for the map display it will not be rotated immediately for course changes below this value. This will make the map display more readable.	15
Navigation	zero SOG detect (20220421)	If the boat is rotated based on COG and there is no movement any more (SOG below limit) switch of course vectors and map rotation. Show a circle for the boat.
Navigation	zero SOG detect below (20220421)	Limit for the SOG (in kn) for the zero SOG detect feature.
AIS	Class B rel size	class B AIS targets can be shown at reduced (increased) size	0.6
AIS	reduce details in AIS list	in the AIS list you can reduce the amount of information that is shown for every target. This can be helpful if you have a laggy display on slow devices.	off
AIS	First AIS label Second AIS label Third AIS label	select which information should be shown near the AIS target on the map	first: name/mmsi
AIS	only show moving AIS targets	if selected - do not show AIS targest that do not move	off
AIS	min speed (kn) for AIS target display	only if "only show moving AIS targets" - the maximum speed of an AIS target to be considered "not moving"	0.5kn
Map	start with last map	if activated the WebApp will directly open the navigation page with the last used map on start up (since 20240616).	off
Map	automatic zoom	If you have locked the map to the boat position the zoom level will be automatically adapted to the available tiles in the area of the current display. So if you e.g. move from an area with higher zoom levels available (like a port) to an area where only lower zoom levels ara available the map display will zoom out automatically (not for o-charts).	on
Map	float map behind buttons	If you activate this setting the buttons and widgets will "float" on top of the map without a fixed background.	off
Map	Increase Fonts on High Res	Increase the symbol sizes and text fonts on high resolution displays.	on
Map	scale the map display	Some raster charts have a display with very small fonts and symbol sizes. This sometimes is hardly readable. With this setting you can scale up (or down) the display of the chart tiles to adapt to your personal preferences.	1
Map	zoom up lower layers	If there is no tile for the selected zoom level available just try to load tiles from lower levels and scale them up. As this requires addtional communication with the server it could impact the performance. The value defines how many lower levels will be tried to find a tile.	4
Map	zoom up lower layers for online sources	The same behavior like "zoom up lower layers" for charts that are directly loaded from the net (also for o-charts). Typically it does not make a lot of sense for such charts - so the default is off(0).	0
Map	Click Tolerance	The "catching area" in pixels for the click on chart objects. A large area would potentially select the wron object, smaller areas could make touch actions difficult.	60
Map	lock boat mode	you can modufy the behavior of the lock button on the navigation page. You can determine at which screen position the boat will be locked. center: center of the screen current: current position of the boat on the screen ask: show a select dialog every time	center
Route	Approach	Destination to waypoint (in meters) for potential switching to next waypoint if: - the distance to the current target waypoint increases and - the distance to the next waypoint decreases
