Nighttime Flight Paths over Dublin

    Hi I have a question for ye good folk if anyone can help. I'm living in Loughlinstown in South Dublin and for the past two nights we've had difficulty sleeping due to a lot of aircraft noise overhead. I was looking on Flightradar last night & the nighttime flights for Dublin airport seem to have been flying directly over our house.

    I saw a few people living nearby complaining on facebook about this & some reckoned the change in flight path was due to winds & someone else said it's because the main runway is closed at night for the next couple of months. Can anyone shed any light on which of these is correct or if it's for a different reason? I'm just a bit worried we're going to have this every night now. It's not a problem I ever expected when we don't live anywhere near the airport!

    I have lost count of the number of times this question appears here.

    The cross runway is often in use late at night to allow for maintenance on the main runway, and also if the crosswinds dictate.

    Varying reasons, mostly because main runway is closed for maintaince, but expect this for several months after the summer when the main runway is overlaid every night.

    Secondly when the wind direction is from the north runway 34 is active.

    Leaving maintenance aside, what's the tipping point (wind direction and speed) which will cause them to switch from 28 to 34? Isn't 34 too short for the transatlantic flights to take-off from?

    It so happens that the wind last night was from the NW so it did appear to make sense to use 34 but someone asked Dublin Airport on Twitter and they said that there was maintenance going on on 28. I was awake after 4 a.m. this morning and two early EI arrivals from Nth America also flew over the southside and landed on 34 between 4:10 and 4:30 before they switched back to 28.

    Night work Sun night to Thur night 2300-0500, tipping point will be when crosswind is above limits causing pilots and ATC an issue eg go arounds.

    If the wind is strong enough the heavies will use 34/16 and not wait for 28 to open again.

    There was a serious incident in Rathmichael on Sunday night, so the police helicopter was in the area for several hours.

    :confused: You know the answer to the OP's query, you supplied it to me on this thread on the same topic over in Dublin South....

    Aswell as commercial planes there was the helicopter which was causing more noise than anything else. Particularly in the loughlinstown area which is mentioned by the OP

    Who also mentioned that he looked on Flightradar and saw the planes flying directly over his house on the way to Dublin Airport.

    We were wondering if there was also a helicopter around on Sunday night as the noise was particularly bad that night, much louder than Monday.

    The police helicopter regularly hovers over that area, pretty much right above my house. I think it's usually along N11/M50 junction, between Loughlinstown and Fassaroe.

    You must live in an area with terribly high crime, so.

    Yep, Rathmichael is well known for its high crime rate :)

    I'm not sure if it's related to crime, I thought it may be traffic related. Or else something is going on in the fields and disused lands around Fassaroe.

    I always thought Rathmichael was wide open for burglaries though, I would have assumed it was that?

    You'd wanna form some sort of neighbourhood watch group if the Garda helicopter is coming over regularly, try and get in touch with them to get to the root of it.

    Sunday's night search was for a extremely serious offence.

    That may be on some database accessible by aviators but on Monday night I checked the Dublin Airport website and scanned back through their tweets - nothing about runway maintenance.

    There is a box 'Latest News' on their web homepage where they may have posted similar notices in the past but there's nothing about this ....

    I'm not particularly wound up about this but it does seem to have affected some people more than others - one guy who lives in D5 has been hammering the minister and the DAA about it on Twitter since Monday night.

    Planes fly over us in Baldoyle/Portmarnock pretty much every morning, noon and night.
    The last Emirates flight can make a right roar if it is taking off over our way.

    Don't you just get used to it?

    I have.

    Quite often I will be woken by the first US flights coming in.
    Then I know I have a couple of hour or 2 of sleep left.
    Happy days for me.

    Same here in Artane/Killester area. When they open the other runway due to wind or whatever they pass directly over our road. You do get use to it. I noticed it when we first moved in but a few years later I don't notice it at all. To be honest it's not THAT loud that it would wake you from a sleep. I guess it depends on how much of a light sleeper ppl are.

    I would have thought the plane would be still pretty high in the sky out at Loughlinstown compared with north Dublin areas, is it really that bad?

    It's not on their website because resurfacing work on the runway during the night is of no concern to anyone except aviation professionals. It is not the first time this has happened. They do not have to send out tweets to people in Loughlinstown or wherever to tell them hey, we're changing runway.

    There is no issue here.

    They do occasionally put it up to forewarn local residents of upcoming noise over affected areas as a result of airfield work but it's not put up daily.

    Traffic over Loughlinstown would usually be above 3000ft on approach. That's not that low. On a good night I can hear 747-400s roaring by overhead at 30,000ft enroute to the US and that'll be with the TV on as well.

    I lived on the approach to 28 up until last Xmas In baldoyle. To be honest you don't hear them after awhile. I now live just off the approach for 34 and even when it's in use I don't hear them. It's a fact of modern life. And let's face it we need the airport. Also it was built long before most of the city.

    Like anything you get used to it. Thank god we don't have bae1-11s in and out anymore ;) they made the 737 200s sound civilised.

    It's not loud enough that it'd wake you, more that it was causing trouble getting to sleep as we're not used to it. It doesn't bother me but my wife's a poor sleeper so it was stopping her getting to sleep. I guess we'll probably stop noticing it after a while. It was very loud Sunday night but we've since established that was mainly due to a helicopter in the area that night.

    RWY16/34 would always typically be used when wind is coming from a northerly, northeasterly or north-north-westerly direction and is in excess of 15 knots. Below that, 10/28 is preferred (unless as is currently the case it is closed at night).

    The flight path of aircraft landing RWY34 forms a straight line from the Killiney to the Pigeon House to the Airport. Link

    It is of concern to some people if two incoming transatlantic planes fly over their houses at 4:30 in the morning when they're not used to that level of noise, especially if it wakes young children or teenagers about to do exams.

    If it's of no concern to you then maybe just don't participate in the thread, otherwise I suggest you let the mods decide what we can and can not discuss.

    Aircraft on final or short final to land are producing perhaps 35% of max power, they generate relatively little noise. This is significantly less of a concern than departing aircraft who on a much more regular basis fly over densely populated areas.

    The most frequently-used departure from both designations of RW10/28 pass equally distant from where I live (EIDW 2.24-10 and EIDW2.24-12 here - aircraft departing 10 would be at perhaps 3,000ft and aircraft departing 28 at perhaps FL80 at their nearest point to me and I'd rate the level of disruption in either case as virtually non-existent. The only aircraft movement that causes any real noise is R117 which crosses directly over the house very regularly at <1,000ft and I'd much prefer they were there than not.

    Let's say these arriving aircraft did wake up people preparing for exams - when I was 17 or 18 I could have counted the time it would take me to get back asleep at 4.30am in seconds.

    I accept your point but when you talk about 'relatively little noise' you're talking about relative to take-off noise, I'm talking about relative to no noise at all.

    One of the factors which accentuates noise from aircraft is that with double and triple glazing, a lot of houses have shut out most lateral sound so a plane flying overhead at 3,000-4,000 feet (whether taking off or on approach) can represent a significant irritant and source of disturbance for a lot of people if they're not used to it.

    Please don't get me wrong here, I know runways need maintenance and even when 28 is open, planes often have to use 34 when there's a strong NW wind. All I'm saying is that in the past, DAA have posted warnings about night flights over the southside on Twitter and their website, this time they didn't bother.

    I understand what you're saying about people who aren't used to the disturbance perhaps being more susceptible to it, and that's a fair point.

    I don't agree that a warning is of any use whatsoever. It's going to wake you or it isn't. Is every student and child in North Dublin going to be shipped to a relative on the southside because there may be some noise in the night?
