Claim:
Navigation lighting device for an aircraft, in particular a military aircraft and preferably a fighter aircraft, with several navigation light units ( 22 , 24 , 26 ) with navigation lights ( 48 , 50 , 52 ), a power supply unit ( 28 ) for the navigation light units ( 22 , 24 , 26 ), and a central actuation unit ( 32 ) for the actuation of the navigation light units ( 22 , 24 , 26 ) in each one of several modes of operation, wherein, the navigation light units ( 22 , 24 , 26 ) for operation in a mode of operation can be actuated by the actuation unit ( 32 ) sequentially in a predetermined sequence and thus with a time offset, each navigation light unit ( 22 , 24 , 26 ) comprises a control unit ( 42 , 44 , 46 ) connected to the actuation unit ( 32 ) for the actuation of its navigation light ( 48 , 50 , 52 ) in the operation mode predetermined by the central actuation unit ( 32 ), the control units ( 42 , 44 , 46 ) of the navigation light units ( 22 , 24 , 26 ) comprise time-delay elements ( 54 , 56 , 58 ) for the temporal delay of the actuation of the navigation lights ( 48 , 50 , 52 ) on the receipt of an actuation signal of the central actuation unit ( 32 ), and the time-delay elements ( 54 , 56 , 58 ) of the control units ( 42 , 44 , 46 ) of the navigation light units ( 22 , 24 , 26 ) are set in such a manner that the navigation lights ( 48 , 50 , 52 ) of all the navigation light units ( 22 , 24 , 26 ) can be actuated by their control units ( 42 , 44 , 46 ) despite a temporally offset receipt of the actuation signals of the central actuation unit ( 32 ).
