Operational procedures



                6.3.5.5     Survival equipment


                NCO.IDE.A.180  Airplanes  operated  over  areas  where  search  and  rescue  are

                particularly  difficult  shall  be  equipped  with  signaling  devices  and  life-saving

                equipment, including means of sustaining life, appropriate to the area to be

                flown.

                6.3.6    Lights to be shown


                The aircraft's lights are described in BL 7-1


                4.2.3.1 During the period between sunset and sunrise, aircraft in flight must

                display:


                   a. anti-collision lights for the purpose of drawing attention to the aircraft

                   b. navigation lights for the purpose of indicating the aircraft's relative flight

                      path to an observer.


                Other lights must not be displayed if they could be confused with the navigation

                lights.

                When  flying  VFR  by  day,  anti-collision  lights  must  be  used  if  fitted  and

                operational.




                The  image  here  shows  how

                navigation        lights       are

                interpreted at night.




                If  an  aircraft  is  approaching

                from left to right, you will see

                a green and a white light.
