Sorry DF,
didnt occur that the initial question was being that specific. Rather just asking who has the older VASIS type slope guidance
In this modern age of high intensity long lived LED. What would it take to make a solid state box as a single fit replacement? Given the choice...VASIS or PAPI?
. I'm sure the likes of Safegate and ALS are working on it. I recall not too many years back one of the presenters from Thorn Lighting proclaimed they were still a long way off having LED rwy edge lights.
