 ANTI-COLLISION/STROBE LIGHTING - DESCRIPTION AND OPERATION
__________________________________________________________
 1. General
_______
 A. The aircraft recognition lighting system is designed as a visual aid to other aircraft, so reducing the possibility of a collosion. The system consists of:
 -an anti-collision light providing a high-intensity red flashing light on the top and on the bottom of the aircraft fuselage.
 -a strobe light providing a high-intensity white flashing light. One light is installed in each wing tip facing forward and one is installed in the tailcone, below the APU exhaust, facing rearwards.
