Pretty poor proof-reading on the ones I have seen. Aberdeen ground/aerodrome chart gets 5 runway designations out of 7 wrong (e.g. refers to Heli Runway 23 as "32H" with a QDM of 189deg)
Scotstown Heli departure refers to "SHE" when it should be "SHD"
And the legend pages have page after page where all the letter "n"s are missing, making it very hard to read. Maybe not so important, but doesn't give any reassurance as to what else they have missed.
Not impressed........
