I have contacted AirNav Ireland, who have operational responsibility for the management of air traffic within the State, and they have informed me that the flights referenced followed standard flight paths out of Dublin airport.
There were no anomalous flights during this period, and all Dublin departures maintained customary altitudes relative to their respective aircraft types and in line with International Civil Aviation Organisation (ICAO) and European Aviation Safety Agency (EASA) regulations.
The list below gives further details of the flights referenced, including their altitude at the time of their passage over the Firhouse area.
