ABSTRACT:
The collision of birds with aircraft is prevented by means of at least one light source installed on an aircraft which produces light flashes. The frequency of the light flashes produced thereby is varied during at least one cycle time period. The frequency of light flashes is advantageously continuously increased one or more times in a range of from approximately 0.1 Hz to 3.0 Hz, and the maximum frequency may then be maintained. Two such light sources are preferably visible to the birds.
