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.
The RTE programme last night showed a revised map issued by the IAA last month (June 2017) of Skellig Michael (of Star Wars fame) another island. On the old map it had the red circle symbol (for a lighthouse) with 174 next to it. No frequency info. There was no height given for the island itself. Only that of the light. 174 appeared in a white rectangle too.
The new map has a blue circle (revised lighthouse symbol?) with text alongside giving a description of the lighthouse (174/frequency etc) but crucially now has the height of the island (712) marked by a smaller black circle. 712 also is now in the white rectangle.
