    Well done to everyone listening to the EIDW feeds, if we where not constantly in the top 50 lists, no one, even less ABC news would notice us. Great day for the feeds!

    Could someone tell me what's 'LATMO'?


    LAPMO. More or less in the middle in the image. It's a waypoint on the approach to runway 28 at DUB.

    Could have some interesting listening on frequency over the next few days. Starting tomorrow from 8am with winds getting up to gusts of 29kts 80 degrees off the nose (if they use rwy 28) before 1pm!

    Also had a look at the surface pressure chart, Sunday evening looks like it will be fun :)

    Hope the Aerial is well strapped up :)

    Looks like we will find out if a chrome metal curtain pole is strong enough for a mast. I admit I'm slightly worried. Although the way the Rg213 coax is routed should act as a safety line, so I don't expect it to hit terrafirma

    Im gonna tighten up the feed a little in advance of this weather coming in, so op's will be gone and maybe a few others, gotta concentrate more on the landings for a day or two.

    Ops can be interesting in sh1tty weather! A lot of the time flight crews will consult with ops as to "what they are going to do next if they don't make it this time" or "where is open that will accept us?"

    I have "doubled up" on the Approach /Tower freq, that means I have inserted the freq twice on the scan list, start and middle. This should mean we get less missed tx from those freq.

    Latest TAF... For those that can't translate.... Ill sum it up for you.... It's going to be SH1TTY! Between 1pm and 3pm is forecast to be the worst with gusts up to 39kts from 200 degrees combined with rain and visibility reducing to 5000m. The whole day from 10am is going to be interesting for us, not so much for the passengers on the planes though so hopefully all will go well and there is nothing more serious than a few go arounds!

    Pilots, it's now time to justify your salaries :)

    Won't be as bad as you think. That's 16 weather and the wind is not that bad vis is fine as well. Light drizzle and occasional moderate rain.

    It would be interesting if it was 220-230 degrees and gusting 40-50+ kt's.

    Come back in the winter months when proper winter storms blow through. This is just a limber up remember the techniques for the pilots wind.

    That's nothing, Roblestone. Totally normal stuff. You should work for the Daily Express!

    Gusts of 40kts normal? Really? Because all the flight planning officers in work, which i have literally left, are saying different!

    The night back in March/April had wind from 230 at 23kts gusting 45kts... Can you remember what happened that night? Its the windshear factor that is going to be the issue here not so much the crosswind.


  • Closed Accounts Posts: 922 ✭✭✭FWVT


    Yes, I remember, my flight next morning was cancelled. But that was winds from the dreaded 220-230 and gusted much higher than 39 knots. Here are the METARs in question. Up to 22037G54 kts

    The TAF you posted earlier would not cause problems. Maybe those in the office were influenced by your reaction?

    Just after turning on the feed and heard the controller tell an aircraft that there had just been two go-arounds and to hold at KEROV ( spelling?) they have now switched runways . Anybody listening in tell me why? Did something happen on 10/28 or is it due to the winds?


  • Registered Users, Registered Users 2 Posts: 12,863 ✭✭✭✭crosstownk


    EIN62R just gone around now and requested runway 28 for next attempt.

    The LiveATC audio is around 20-30 seconds behind flightradar24

    Yeah. That can happen. Sometimes if you refresh the feed it can alter the delay (either way).

    Probably the wind :D


  • Closed Accounts Posts: 922 ✭✭✭FWVT


    A bit of a mess there with the wind switching back to R28. Two aircraft abandoned approach for 16. Still only gusting 31 knots from 240


  • Registered Users, Registered Users 2 Posts: 12,863 ✭✭✭✭crosstownk


    EIN523 diverted to Aldergrove. Fuel may have played a part in that decision.

  • Closed Accounts Posts: 922 ✭✭✭FWVT


    Yes, he had only just been told aboit the change to 28 and he asked how long it would take as they were looking at their fuel. They hadn't even been holding at that stage so they must have been cutting it fine.

    Ask urajoke (who seems to be an ATC at Dublin) if it was anything major. As I said, a few go-arounds due to shifting wind-direction, not speedshear. The max gust recorded all day was 19 m/s (37 knots) between 2-3 pm, with a pronounced veering at 14:36, as per the 3 pm synop.

    I never said it was going to be major, I said it would be an interesting day to be listening on frequency... Which it was!

    Winds shift every day but it doesn't cause go arounds unless it is sudden wind shifts in direction.... Which guess what? Is windshear!

    ICAO definition;

    Wind shear is defined as a sudden change of wind velocity and/or direction.
    Windshear may be vertical or horizontal, or a mixture of both types. ICAO defines the vertical and horizontal components of wind shear as follows:

    Vertical wind shear is defined as change of horizontal wind direction and/or speed with height, as would be determined by means of two or more anemometers mounted at different heights on a single mast.

    Horizontal wind shear is defined as change of horizontal wind direction and/or speed with horizontal distance, as would be determined by two or more anemometers mounted at the same height along a runway.

    Yes, winds shift many days, and today was another such day. There is a difference between randomly-varying winds and veering due to a frontal passage, which is what today was. First the backing this morning from the warm front, then the veering with the cold front. A pain in the ass but for me it rates about a 3 out of 10 on the "listengingonfrequencyability" scale! I've heard many more exciting days than this. The most interesting part for me was how soon EI523 started making noise about its fuel situation when it was only at Slane, just about to start its normal approach for 16. they said they could only hold for a max of 10 minutes and then almost immediately went to Aldergrove. That to me seems to be too close. All others in front of it were vectored directly for 28 with no holding and landed without incident.

    Even with the strong enough wind and rain here today it all seems to have been taken in their stride at EIDW. Needs a bit more effort from mother nature to take down my antenna also. All good.

    The wind needs to be split 60degrees or so between 28 and 16 and gusting 40+ kt's to be of interest or 50+ for less of a crosswind to cause trouble.

    Even less of a gust lower down can force a go around if it's in the less couple of miles if it causes the aircraft to become unstable.

    Don't worry there will be another major Atlantic storm along shortly I'm sure that will prove good listening. Plus many days of fog and possibly snow that will as usual cause a shutdown.

    just landed on 28 on the 485 from Lisbon. quite a pleasant flight and very very minimal chop on approach although I believe later things might be a bit more interesting but the forecast seems tosuggest little of the go around and holding action that the initial weather antipated..
