An amazing piece of Air Law!
In case anyone was worried about the Air Law exam, don't forget the following rule under Obstacles and Emergency Services:
Requirement for marking/lighting............the marking may be omitted when the obstacle is lighted by high intensity obstacle lights by day; and the lighting may be omitted where the obstacle is a lighthouse and an aeronautical study indicates the lighthouse to be sufficient.
Marvelous stuff - Good luck to all candidates!
