Approach Lights
Can any of you learned Ppruners shed some light (no pun intended) on an issue that has been bugging me for years?
Is there any significance in the runway approach light configuration? I've seen all sorts of combinations of numbers of rows and numbers of lights in those rows, and they seem to be different wherever you go.
I've even asked the airfield licensing department of the Campaign Against Aviation, and they couldn't answer the question.
