Field notes
AirportFM distinguishes movement energy from aircraft count: flight phase, speed and reported size affect each contribution, while stationary aircraft add a hum but no rhythmic energy. Heathrow’s default full-mix reference is 14 weighted activity units, explicitly described as an artistic setting rather than a measurement. The page attributes aircraft positions to ADSB.lol and says the feed trails the sky by about 15 seconds.
