Aerial Lighthouses

Those maps are updated every so often so it may be that later editions might show Cruden Bay. I think 1940 was the last time a lot of detail was shown.
 

Just dug out my box of maps and none of those covering the Aberdeen area show any aerial lights. The only thing shown is a golf course!
I have editions covering 1931 and 1936 and also a badly cropped one that I can only date by the magnetic variation as being June 1939. I suspect a lot of stuff that should have been added to 1939 editions didn't make it and to date I have not found any 1940 editions.
 

P.S. I suspect the magnetic variations were predicted dates so that they would be about right when the map would actually be used - can anyone confirm this?

Sadly I didn't save links to the various maps and just took screen grabs of the bits showing ranges. I did save down a number extracts I found on the internet, mostly long gone Ebay items.
From those extracts I gleaned the following: - 
In 1929 Air Lights were at Penshurst (Aerodrome), Croydon (Aerodrome), Tatsfield, Cranbrook (?), Lympne (Aerodrome), Littlestone (Aerodrome), Dungeness. The other South Coast areas west of Portsmouth didn't have any by the looks of it.

In 1938 the air lights list attached for the SE area map.


In 1939 (From disjointed extracts) Worthy Down (Aerodrome), Eastleigh (Aerodrome), Speke (Aerodrome), Yeadon (Aerodrome), Leicester (Aerodrome), Waddington (Aerodrome), Cranwell (Aerodrome), Northolt (Aerodrome), Ratcliffe (Aerodrome), Upavon (Aerodrome), Aldergrove (Aerodrome), Hatfield (Aerodrome), Hornchurch (Aerodrome), Duxford (Aerodrome), Bircham Newton (Aerodrome). 

Not a complete list by any means but it does seem East and South East biased and by 1939 all seemed to be aerodrome based. I assume as aviation progressed before WW2 some lights became redundant or too expensive to maintain. Nothing was found in Scotland but as coverage was incomplete this is no guarantee there were none.

With the Flight online archive no longer available searching back issues is not possible either.
