Other than vessels, if there were any, no other surface lighting visible at a best viz of 7 km., or even higher ground near Blacksod light, certainly not Blacksod light. High ground intervenes.
Isn't it inconceivable that they could see the light and still hit the rock?
Can anyone venture an opinion of what happens to a stratified layer over ocean when a rock intrudes to 300 feet, and there are 20 knot gusting winds coming up the sides of the rock. The orographic effect needs a higher rise than that to be significant, or...? More of a mariner than aviator question, but can the weather be different in the area of the rock than it is a mile away over flat ocean?
How much cloud depth, i.e. ceiling lower than the light itself, will result in the light not being visible?
