Why a plane flew over Heathrow Airport multiple times in middle of last night

A small plane operated overnight calibration flights at London Heathrow, violating the airport's curfew. The Diamond DA 62 completed multiple maneuvers, including touch and go landings, on both runways 09R and 27L, and also conducted calibration checks on runways 27R and 09L. The operation, which began after hours, raised concerns and prompted warnings from the airport via social media regarding the inconvenience caused to local residents. In the field of transportation, it is essential to balance operational needs with community impact. Overnight calibration operations are critical for ensuring the safety and efficiency of airport runways, but they should be planned with greater consideration for curfews and local noise regulations. Conversations between airport authorities and local communities could help mitigate potential disturbances while accommodating necessary operational procedures.
