Go-arounds

Newest first, Irish time

    A go-around is counted when an aircraft established on the final approach, within 5 nm of the runway and below 2,500 ft, climbs at least 300 ft over three or more reports without touching down. Most are routine: a runway not yet clear, wind shear, or an unstable approach.

        Emergencies

        Squawk 7700 or 7600, all of Ireland

          An aircraft squawking 7700 (general emergency) or 7600 (radio failure), or reporting an emergency state, on at least two reports. Most end with a normal landing. Hijack codes are not shown: spoofed and mistaken ones are common.

          Holding and circling

          At least one full turn in one direction, roughly level

            Aircraft below 7,000 ft over a 2 km square

            Tap the map, or use your location, to see how many aircraft pass low over that square each day, how low, at what times, and an estimate of how many are loud. Your location is rounded to about 100 m and used only for this question.

            How the local numbers are made

            Skylark joins each aircraft's reported positions below 7,000 ft into a path and counts it once in every 2 km square the path crosses. An aircraft that comes back more than 45 minutes later counts again, so a morning and an evening rotation are two overflights. Altitude is barometric and treated as height above sea level, so over high ground the aircraft is closer than it looks here.

            The loudness estimate takes a typical maximum level at 1,000 ft for the aircraft's class (light aircraft 68 dB, turboprops and regional or business jets 77, helicopters 78, single-aisle jets 82, wide-bodies 88, 3 dB more when climbing), and reduces it for distance and air absorption. N60, N65 and N70 count the overflights estimated to reach 60, 65 and 70 dB at the ground directly below. Several dB of error are normal; real levels depend on the engine, weight, weather and the ground.

            About this record

            One collector reads the whole island: a paced public feed poll every 20 seconds and Skylark's own receivers every 5 seconds. Everything here is worked out from those positions on Skylark's server. A missed report can hide a movement, and nothing on this page is an official airport statistic.
