Black dot for light house!
I just pulled out my Dads old ICAO 1:500 000 VFR chart to check how a lighthouse is marked.:
It is with a black dot, no elevation or height and Feiestein Light ( WestSW of SVG for example)
And in the margin a fine drawing of the lighthouse with 112 on top of it.
Probably a fine thing for Mr VFR on one of his trips to Stavanger for coffee and waffels, but rather crude even if at scale 1:250 000 for any low level night stuff.
Anyway, if the chart had used the ICAO Annex 4 black dot with Blackrock Light printed next to it, we would perhaps not have had this exchange.
