The height of fire carriers is the building height of fire carriers, i.e. fixed navigation signs carrying a light . These can be lighthouses , beacons or masts of all kinds. It is usually measured over the ground. The height of the fire carrier must not be confused with the height of the fire , as this indicates the height of the light source above sea level.


The upper measuring limit for lighthouses on the German coast is the height of the roof ridge. The ridge is the tip or crown of the roof. In beacon using the height of the top mark. The lower measurement limit is the ground level on which the tower is built.

The fire carrier height of lighthouses can be found in the beacon directory . On lightships the fire tower height is transmitted and lighthouses in the water indicated above the water level.

In classic nautical science, the height of the fire bearer is important because the comparison of the true height with the angle of elevation measured from the ship indicates the distance from the navigation mark. Since, for example, lighthouses were preferably erected on land ledges, this method allows safe sailing around the shallow water areas that are often in front of them, by always maintaining the elevation angle required for a safe distance and not exceeding it. A precise location determination is possible with the bearing and distance procedure .
