The runway needed permission. daa says the routes do not.

This is one real Thursday at Dublin Airport, what if they sent flights over your house instead?

    On 20 August 2026, — jet departures left Dublin Airport's North Runway. The orange threads are where they actually went. The white bar is the runway, and it never moves on this page: it was built under a planning permission and it is where it is.

    Where the aircraft go afterwards is another matter. daa's position, given to an Oireachtas committee in January 2023, is that flight paths are "not a factor of our planning permission". On that account nobody's consent is needed to send the departures somewhere else.

    So pick a street. The routes swing round to it while the runway stays put: the same aircraft, the same hour of the morning, the same height at the same distance from the same runway end. If departures already cross the spot you pick, nothing is moved and you are shown the real day.

    How this is worked out

    The flights are the real ones: every departure recorded off runway 28R on 20 August 2026, with its aircraft type, its time off the runway and its track. Turboprops and ten flights with no recorded type are left out, so the count here is lower than the day's 372.

    Where a place already lies under a departure route, no turn is applied and the figures are simply that day. Turning the airport for someone who is already under it would overstate what they live with, and they can check the page against their own morning.

    The turn is a rigid rotation of the routes about the departure end of the runway. The runway does not move, because it could not be moved without a planning permission; the routes move, because daa says they need none. Every aircraft keeps the height it really held at that distance from the end of the runway, so the turn cannot make one lower or louder than it was.

    One simplification in the reader's favour, stated plainly: a real change of route would turn the traffic over a few kilometres rather than pivot it at the runway end. This page swings each track whole, to show where the traffic would end up rather than to draw the departure procedure that would take it there. Heights, speeds and power settings are the ones actually flown.

    The noise is daa's own measurement. The level of each type at each distance comes from a propagation law fitted to 364,831 noise-monitor events that daa itself recorded and released under access-to-information request AIE 2611. The figure is a single-event peak (LAmax) outdoors; indoors with a window open is appreciably quieter.

    Two simplifications worth knowing. Ground height is taken as a constant, so places on higher ground are treated as slightly further from the aircraft than they are. And positions arrive about every sixteen seconds, so the closest approach is interpolated between them.

    Nothing you click is sent anywhere. The place you pick is held in the part of the web address after the # symbol, which browsers never transmit to the server, so the link is shareable and the server still never learns it.
