By Matt Mills-Brookes, Senior Airport Specialist, Envirosuite, and Peter Rafano, Airport Business Development, Envirosuite. The aviation industry has experienced a high rate of change in recent years, the continual growth in air traffic resulted in operational noise and emissions concerns from a wide range of stakeholders, highlighted by the Flygskam (flight shaming) campaigns. The resulting infrastructure and airspace change programmes required to deliver that continual growth has reinforced those concerns. Aviation attempts to manage noise has resulted in a disconnect. Noise reduction programmes aimed at offsetting the growth and annoyance have delivered reductions in noise, but at the same time noise annoyance has increased.
