Section 2 RotA: S8 - Lights and other signals to be shown

Question 1

48: Failure of navigation and anti-collision lights

What are the rules when lights required to be displayed fail when the aircraft is on the ground or in the air, day or night?

Answer 1

• An aircraft shall not depart from an aerodrome if a required light fails and the light cannot be immediately repaired or replaced, day or night
• An aircraft in flight when a required light fails shall land as soon as it can safely do so, unless authorised by the appropriate ATC unit to continue its flight
• An aircraft may continue to fly during the day in the event of an anti-collision light failure provided the light is repaired at the earliest practicable opportunity
