Review of existing Section 106 Agreement - Thanet District Council

is unclear whether 12 landings and takeoffs (ie 24 movements) are meant byPara 1.4.2.In the past KIA has been an airport where major maintenance was carried outon older aircraft operated by countries outside of Europe and the US, wherenoise regulation is less demanding. Many of these aircraft fall into the Chapter2 classification, and cannot now be legally operated by western airlines. Ifhowever business opportunities still exist on KIA for such work, considerationmay need to be given to whether any such aircraft will be allowed to operateinto and from the airport in the future, even on a restricted basis, and whetherthe S106 should reflect this issue.Under penalties in Para 1.5.1, the recurring noise violations penalty isrestricted to the “same aircraft”, that is to say, an individual and specificaircraft. An airline may operate a number of different aircraft of similar typethroughout its service network, it is therefore suggested that the definitionshould be changed to cover cumulative violation repetitions by any aircraft ofthe same type operated by the same carrier.Reference is made in several paras to aircraft Quota Count (QC) scores.These stem from the nightflying movement and night quota system formallyoperated at the three Designated Airports (Heathrow, Gatwick, Stansted) andoperated on an informal basis at a number of other non-designated airports.The QC “score” is a shorthand for the degree of noise created by an aircraftfor both takeoff and landing. The QC is based on the Certified Noise Levelsas follows:Quota Count Scoring SystemCertified Noise Level (EPNdB)Quota CountMore Than 101.9 1699-101.9 896-98.9 493-95.9 290-92.9 1Less than 90 0.5Schedules giving the Quota Counts for each aircraft type, subtype and enginefit are published by the CAA as part of its Aeronautical Information Services(AIS).However this is only one part of a night flying restriction process that sets amaximum number to the actual movements (takeoffs or landings) allowedduring the night period, in addition to setting a maximum Quota Allowancebased on the noise of any movement. The limit to night time activity is whichever of these two elements reaches its limit first. It encourages the use atnight of the quieter aircraft (for example eight movements by QC0.5 aircraft“use up” the same Quota Allowance as a single movement by a QC4 aircraft).In considering a future Night Flying Policy the setting of both a limit to thenumber of movements and to a maximum quota allowance should beconsidered. The amount of quota can be set to ensure that a limited numberof night slots are used in the least intrusive way. Simply having a NightMovement limit alone does not have this incentive.EU00142:FINAL REPORT PAGE 26
