Does that mean that beacon mode is always on?

Seems a bit pedantic - 'pop up' is a mode of operation of the EGPWS, and is clearly stated as such in the RFM, using that terminology.

Wikipedia - List of Light Houses still has Blackrock listed with a tower height of 15 mm/ 49 ft . What do other data bases have the height?

The Commisioners of Irish Lights who operate the lighthouse state the height of the light as 282 feet MHWS and the height of the tower as 49 feet

And isn't 15mm a bit small for a lighthouse?

... and wikipedia also lists the focal hight, which is imminent for navigational purpose ( distance of visibility ) as 282 ft.

So the top of the lighthouse should be some feet higher...

I suspect it is a debate about whether or not it should be in the obstacle database. 50 ft is usually the cut-off in none urban areas.

I expect that some people would see it as informative as to what happened.

Because there's a huge light on it? Shining in your windscreen? Telling you it is not Blacksod?

IFR cloud break procedures.

Have been following Rotorhead since last spring , mainly the Puma accident in Norway.
I have great respect for what you all do.
Can anyone please tell me when you all started going IMC ( IFR if it was planned and approved)
And then doing Cloudbreak procedure, for a better word outbound, rig ship or wreck?
I am guessing it is something that started in the Northsea Oil industry ca 1970?
Outbound stay VFR find rig, Inbound SVG go IFR and shoot ILS.
Then what?
Did they give NDB,DME on rigs?
OK , so we use WX radar in MAP mode, radio alt, EGPWS. And lastly the LNAV VNAV PATH based on all these sats , vor dme IRS. When, and how.
Basicly looking for a historic timeline for the evolution of North Sea and European SAR IFR approches.
Regards from an Fixed Winnger

Yes, it does. But if you are at 270 feet, the light would be below you, not above.

Indeed, but Blacksods' light has a quite different characteristic, so's we simple seafarers can tell the two apart.

120 fishing boats/trawlers from the Irish fishing fleet are undertaking a co-ordinated search for the missing crewmen.

120 boats search for missing Rescue 116 crewmen

The search line can be seen in real time at www.marinetraffic.com; it should be noted that only vessels exceeding 300 tons are required to carry an AIS transponder so for every vessel you see on their map display there are about 8 others between them.

The sweep, which has been planned by three fishing industry organisations (The Killybegs Fishermenís Organisation, Irish Fish Producersí Organisation and Erris Inshore Fishermenís Association) in response to an appeal by missing crewman Mr Smithís sister, Orla, set off from the crash location at Blackrock island, 13km west of the north Mayo coast, at first light today. The South Donegal and North Mayo coast has been divided into a number of search areas, each under the direction of an RNLI or Irish Coast Guard asset. The Naval Service ship L… Ciara will be on scene ready to assist where required.

It's an excellent idea - the local fishermen will know the tides and any local effects far better than the CG computer which will generate a massive potential search area.

which reminds me of a search in Cardigan bay for an overdue 12' speed boat with three teenagers who'd run out of petrol and drifted 20 odd miles downwind of Borth. The CG computer had a Nimrod searching off the Isle of Man by first light. We ignored the 'plot' and flew direct to where we calculated they'd have drifted to. Picked em up early am. No flares or radio. CG astonished that Nimrod hadn't found them in the dark "but they can find a needle in a haystack" said DC Milford CG!

Also
A group of over 70 divers who are trained in search and recovery have launched 18 ribs to assist, as part of an agreement between the Irish Underwater Council and Irish Coast Guard.

Great effort to get a little armada out to help.

Strange that the Navy don't have many small ships to help out, like the HMS Ranger that was docked in Cork.
