ANTI-COLLISION LIGHTS
(a)An anti-collision light system should be installed to attract attention to the VCA and provide sufficient visibility in a timely manner for other aircraft to avoid a collision, especially in congested areas. The system should consist of one or more approved anti-collision lights. Each anti-collision light should be either aviation red or aviation white.
(b)If installed, red flashing anti-collision lights (rotating beacons) should not affect the vision of the pilot or detract from the visibility of the position lights. The red flashing lights should be turned on when the lift and thrust units are powered on prior to taxiing or movement of the VCA on the ground and should be turned off at the end of the flight.
(c)If installed, white flashing anti-collision lights (strobes) should be so located that the pilot’s vision is not impaired. The white flashing lights should be turned on prior to take-off and turned off immediately after landing.
