Warning lights on tall structures for aircraft

[AndyClockwise]

There is a tall structure visible from my front window which has a series of red lights on it (presumably so that aircraft avoid hitting it)

This is only visible during night time and whichever object it is blends into the background during the day.

Is there a map of such structures that I could search and so work out what it is?

I have tried Google maps but it doesn't show anything

The UK Aeronautical Information Package has a list of en-route obstacles, found here:

You'll need to navigate down into ENR 5.4 - the site is served by a Eurocontrol CMS which makes linking to specific documents a transient affair.

Temporary structures aren't typically listed, publicised by NOTAM instead. Whereabouts is this structure?

[AndyClockwise]

It's on the outskirts of Bristol - I'm thinking it's a TV mast but not sure

Check the AIP there, local charts should have the mast on there.

Thanks Ed - will have a look when I get home

Whereabouts on the outskirts of bristol are you and which direction from your location is the mast?

Is it BT Purdown?

[AndyClockwise]

I'm in St George and it's South East from me so looking at Google maps it's Keynsham or Marksbury direction.

I will look again tonight with a compass and using the map as already advised

Probably the Wells/Mendip TV mast:

Pretty famous for us aviators as it's close to Bristol Airport's approach for runway 27. It's marked quite clearly on all aeronautical charts thankfully. 1000ft high!

Moose - yes I think it is the Mendip transmitter

The Mendip Transmitter is a VRP, but it's base is about 1000' amsl and the top is over 2000' amsl, so often gets shrouded in cloud, where the light is invisible.

If you are routing that way, under the Bristol CTA, Bristol will always check that you are visual with the Mast. No doubt paranoid that someone will fly into it and take everyone's TVs out.
