Legend {#little-navmap-legend}

By default, all speeds are given in knots, distances in nautical miles, altitudes and elevations in feet. The units can be set to imperial or metric in the dialog Options on the tab Units.

Colors, size and text labels of some map elements can be changed in the dialog Options on the tab Map Display. This legend shows the default values.

Heading and course are suffixed with °T for true course or °M for magnetic course.

	VOR or NDB range rings labeled with ident and frequency. Color indicates Navaid type.
	Great circle distance and course measurement line indicating length and true heading at start and destination. The two heading values will be equal for small distances. For shorter distances length is also shown in feet or meters.
	Rhumb line of equal bearing distance measurement indicating distance and true heading. Rhumb lines are used to approach a VOR or NDB or travel along airways. For shorter distances length is also shown in feet.
	Measurement lines starting from an airport or navaid have the same color and additional ident and frequency labels. Course for rhumb lines will be shown in magnetic if the navaid has a magnetic variation attribute.

Airports {#airports}

Airports having control towers are shown in dark blue others in magenta. Add-on airport names and idents are shown italic and underlined. Airports that are part of the flight plan have a light yellow text background.

The symbol is shown smaller if an airport has no runways. This is the case for some add-on airports that use another technique like photo scenery to display runways.

	Waypoint with name.
	User-defined waypoint with name.
	Invalid airport, waypoint, VOR or NDB that is part of the flight plan but could not be found in the Scenery Database.
	Marker with type and heading indicated by lens shape.
	Jet airway with label showing name, type (Jet or Both), minimum and maximum altitude. Text depends on zoom distance. A preceding arrow will show the allowed direction if the airway is one-way.
	Victor airway with label showing name, type (Victor or Both), minimum and maximum altitude. Text depends on zoom distance. A preceding arrow will show the allowed direction if the airway is one-way.
