Talk:Aerobeacon

Split from aerodrome beacon

edit

I have split this out as a separate article because the illuminating device was widely used in lighthouses as well as at airports, and it is inevitably referred to as an aerobeacon in works on the former. Mangoe (talk) 16:44, 14 June 2012 (UTC)Reply

Need correct images

My edit was cut off... sources for description change below. The image was changed before from a WWII searchlight... to a WWII searchlight. Please find an appropriate image :|

Lens description

edit

The photo shows some sort of lens mounted at the outside front surface of aerobeacons, but the details of the design of this lens seem not described in the article. Are these vertical prisms of some sort? Are Fresnel Zones involved at all? I should think this important information, if it is true (as is implied) that aerobeacons are systematically replacing lighthouses. David Spector (talk) 16:46, 14 October 2021 (UTC)Reply

There is a discussion of aerobeacons here. It seems that some aerobeacons relied on mirrors, while others used a variety of Fresnel lens. That is the only source I've found in a quick search, and I would be cautious about using it. - Donald Albury 20:04, 14 October 2021 (UTC)Reply

Just curious why you use the past tense for "rely". Are aerobeacons obsolete too? Then what is currently used for warning sailors of rocks or sand bars? Perhaps a whole family of related articles (Lighthouse,United States Lighthouse Service,Fresnel lens,History of lighthouses,History of lighthouses in Canada--this one omits the 21st century) need updating too?

My impression is that the aerobeacons that used mirrors were from the first half of the 20th century. See VRB-25 for a beacon, sometimes called an aerobeacon, currently in use in lighthouses. - Donald Albury 23:17, 14 October 2021 (UTC)Reply
