Abstract

An erosion detector for an exterior aircraft lighting device is configured for detecting the state of erosion of an at least partially transparent cover of an exterior aircraft lighting device and includes: at least one light source, which is configured for radiating light onto the at least partially transparent cover; at least one light detection element, which is configured for detecting light reflected by the at least partially transparent cover and for providing a corresponding detection signal; and an evaluation unit, which is configured for evaluating the detection signal for determining the state of erosion of the at least partially transparent cover.
