    FR9902 Málaga (AGP) to Cork (ORK) diverting to Shannon due to wind at Cork.

    Made 2 failed attempts at landing.

    Saw it earlier from my bedroom as its search light was active. Never seemed to descend so probably a training exercise. They do quite a bit of that around the Malahide estuary.

    A AN12 just flew over Dublin heading up north along the east coast. Lovely unusual sound.

    UR-CGW has just flown over Dublin northbound. No destination info.

    Nice to hear an AN-12 in this neck of the woods again.

    EDIT: It has just landed at Prestwick.

    some sort of a small jet flew low West of Lough Ree today. No tracking on FR24. Would this be military?

    Also noticed a small cessna (probably doing mapping) that was flying over Lough Ree (took off from Knock this morning) disappeared from FR24 suddenly just now i.e. all previously tracking disappeared along with current position.

    Not tracking on FR24 may be a function of altitude, as FR24 is dependent on the location of the people feeding data from their receivers to the site. The lower an aircraft, the less likely it is to be picked up by receivers at a distance.

    Casa 253 was out west today, you may off seen that. The light aircraft you saw was EI-FII out from Abbeyshrule, they were over at Knock doing some VOR work (Knock was closed today but you can still work off the VOR)

    Thanks for the responses, looked like the pc9m so that explains that alright!

    Taking more notice of the few planes and helicopters we do see, now that the skies are quieter!

    https://www.flightradar24.com/data/aircraft/n700el#25f637e1

    Live in a 10 story apartment block in Dublin, this plane just flew overhead and looked like it couldn't have had much clearance. Flightradar24 states it was at an altitude of 350ft. Is that not incredibly low for flying over built up areas in Dublin city centre?

    The altitude FR24 receives from the aircraft transponder is based on standard pressure of 1013.25 hectopascals.

    At that time today, the actual atmospheric pressure at Dublin was 1037hPa. The rule of thumb is roughly 30 feet per hPa, so that’s about 720 feet difference, so roughly 1,070 feet.

    Q. Do ATC work off the same transponder data and calculations?

    ATC radars receive the same data, referenced to 1013 hPa, but our systems automatically adjust it to the local QNH below the transition level for display on screen.

    Thanks! Out of curiosity, does anyone know what the minimum flight height above a city/built-up area is for private aviation?

    ICAO rules of the air.
    4.6 Except when necessary for take-off or landing, or except by permission from the appropriate authority, a VFR flight shall not be flown:
    a) over the congested areas of cities, towns or settlements or over an open-air assembly of persons at a height less than 300 m (1 000 ft) above the highest obstacle within a radius of 600 m from the aircraft;
    b) elsewhere than as specified in 4.6 a), at a height less than 150 m (500 ft) above the ground or water.

    And this.\
    Minimum heights
    Except when necessary for take-off or landing, or except by permission from the appropriate authority, aircraft shall not be flown over the congested areas of cities, towns or settlements or over an open-air assembly of persons, unless at such a height as will permit, in the event of an emergency arising, a landing to be made without undue hazard to persons or property on the surface.

    In the good old days, when Pontius was a pilot and I learned to fly, it was

    Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:
    (a) Anywhere – An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.
    (b) Over congested areas – Over any congested area of a city, town, or settlement, or over any open-air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.

    (c) Over other than congested areas – An altitude of 500 feet above the surface except over open water or sparsely populated areas. In that case, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

    So don’t watch Catch 22 when the guy low flies over the sea....
