The highest numbers of complaints received in any calendar month during 2014 were the 232 received in July from 134 complainants. This same month in 2013, 2012, 2011 and 2010 also recorded the highest number of complaints in any month during those years. The next highest complaint totals received were in June (113) and September (196) from 82 and 78 complainants respectively. The complaints received in June, July and September coincided with the increased percentage of Runway 04 (North Easterly) usage, June 49%, July 49% and September 67%. We would normally expect the summer average runway 04 (North Easterly) movements to be approximately 30%. During 2014, a total of 1022 complaints were received from 427 people. Within these complaint totals, 209 complaints (20%) were received from 7 people, including 2 complainants from the same address who registered 87 complaints between them, totalling 8.5% of all complaints received. The locations of the top 7 complainants, 6 separate households, in 2014 are shown on the map below. 3 of the7 highest complainants are affected by departing aircraft to runway 22, with all 3 located under the 22CLN and 22DET departure routes. One is affected by 04 departures located near the end of the 04 CLN noise preferential route. One is affected by arrivals to both runways and there are one each effected by arrivals to runway 04 and 22 respectively.
