Nav lights
A question that has come to mind as I have recently done the shore based study for the RYA Day Skipper.
Why in aviation do we divide the red/green/white nav lights into 120 degree sectors while our maritime brethren use 112.5/112.5/135?
Given that the maritime standard was probably devised before the Wright brothers were born why have we chosen to be different or was there no maritime standard until much more recently?
