Heathrow Airport Flight Performance Q3 Report 2014–Page 3
This report covers January to September 2014.
The period from January 2014 to the end of Q3 has seen68.73% westerly operations and 31.27% easterly operations.September alone saw a long period of Easterly operations at52.88%.
1000ft infringements are up on Q3 for 2013 from 454 to 550.Of the 550 infringements to the 1000ft requirement, 138 ofthese were below 900ft. Once again we continue to seefluctuations in the 1000ft infringements due to hightemperatures resulting in more infringements.
Night noise infringements are once again down on this timelast year. There have been 24 Night noise infringements to theend of Q3. 7 of these departing in the shoulder periodbetween 2300 and 2330, and 17 departing after 2330 whenrestrictions are at their tightest. There have been 8 Day Noiseinfringements for the period. This is the same figure as seen inthe Q3 2013 period.
Flight Performance continues to provide noise data to BritishAirways Aircraft Performance Team for their A380 departures.
Track Keeping All Runways has seen a small decrease inpercentage on the same quarter last year. From Jan-sept 14there have been 11269 deviations out of a total of 177452departures resulting in a 93.65% compliance.
CDA remains up on the same period for 2013, with all fourreporting periods showing improvement.
Joining Point Night Lows continue to show improvement.Joining Point Day Lows are also improved in comparison to2013. However Day Lates and Night Lates are slightly higherthan the figures for Q2 2013. Late joiners are typically undertactical instructions from ATC, vectoring aircraft foroperational reasons on the day.
Summer 2014 Night Quota and Movement figures continuewell.
The complaint callers have increased for the 2014 Q3 period.The rise is this figure is due to a series of airspace trials takingplace in 2014 resulting in a large number of callers.
All charts and graphs are shown on the pages that followare for reference purposes only.

** Excess usage pro-rata indicates increased risk of aircraft being refused permission to arrive or depart during 23:30-06:00hrs local
*** Significant increase in contacts or callers relative to enquiries can indicate a rise in demand on the FEU
**** Low numbers of departures off 09L due to the Cranford agreement can result in a wide fluctuation in performance when compared tothe other three runways.

KPI chart to end of September 2014
Each element of this report is preceded where applicable by the relevant Aeronautical Information Publication (AIP)reference and summary text detailing the purpose of the requirement. Data is then presented on current performance.
It should be noted that Heathrow is 83ft above sea level and the ANOMS NTK system measures height relative to Heathrowelevation and not sea level. References in the AIP are usually above sea level (quoted as Heathrow QNH) and therefore needto be reduced by 83ft to be comparable with heights as measured by ANOMS. No account is taken of the variability ofheights as measured by the radar which, depending on the distance from the radar head can be +/- 200ft from thatindicated. This is obviously allowed for by NATS when managing operations.
FOR THE PURPOSES OF THIS REPORT ANY REFERENCE TO HEIGHT SHOULD BE READ AS ABOVE AIRFIELDELEVATION UNLESS OTHERWISE STATED.
ALL DATA CONTAINED WITHIN THIS REPORT SHOULD BE CONSIDERED IN LIGHT OF THE PRECEDING TEXT ANDCOMMENT BOX THAT FOLLOWS.

Departure Noise Limits
Subject to sub-paragraphs (5) and (6) below, any aircraftshall, after take-off, be operated in such a way that it willnot cause more than 94 dBA Lmax by day (from 0700 hoursto 2300 hours local time) as measured by any noisemonitoring terminal at any of the sites referred to in sub-paragraph (2*) above.
Subject to sub-paragraphs (5) and (6) below, any aircraftshall, after take-off, be operated in such a way that it willnot cause more than 89 dBA Lmax by night (from 2300hours to 0700 hours local time) and, that it will not causemore than 87 dBA Lmax during the night quota period(from 2330 to 0600 house local time) as measured by anynoise monitoring terminal at any of the sites referred to insubparagraph (2*) above.
(5) The limits specified in sub-paragraphs (3*) and (4*)above shall be adjusted in accordance with the followingtable in respect of any noise monitoring terminal at anyof the sites referred to in the table in sub-paragraph (2*)to take into account of the location of that terminal andit’s ground elevation relative to the aerodrome elevation.
(6) For the purposes of determining an infringement of thelimits specified in sub paragraphs (3*) and (4*) above, ifthe aircraft was requested to take-off with a tailwind, anamount of up to 2dB of the noise recorded at the noisemonitor should be disregarded.The amount to be disregarded shall be:0.4 db for a tailwind of up to 1 knot.0.8 dB for a tailwind exceeding 1 knot but not exceeding2 knots1.2 dB for a tailwind exceeding 2 knots but notexceeding 3 knots1.6 dB for a tailwind exceeding 3 knots but notexceeding 4 knots2.0 dB for a tailwind exceeding 4 knots
For this purpose, tailwind is to be calculated from the winddata measured in the on-air field anemometers and windvanes according to the formula:(windspeed x cosine (runway heading minus winddirection))x-1

Departure Track Keeping
For monitoring purposes, a departure will be deemed to havecomplied with the Noise Preferential Routeing (NPR) if, in theportion of flight below the appropriate vectoring altitude (seenote 9 right), it is properly recorded by the airport’s noise andtrackkeeping (NTK) system as having flown wholly within theLateral Swathe (LS). The LS is defined from the centre-line ofthe relevant route coded in the NTK system, based upon amap accredited for this purpose by the Department forTransport, by the closer to the centre-line depicted on the mapof (a) a pair of lines either side, each diverging at an angle of10° from a point on the runway centre-line 2000m from start-of-roll; and (b) a pair of parallel lines representing a distance of1.5 km either side of the route centreline. For avoidance ofdoubt, the depicted route and LS may include curved sectionsrepresenting turns.
Note 9.
Aircraft which have attained an altitude of 4000 ft ( HeathrowQNH ) may be directed by air traffic controllers onto a differentheading and commanders complying with any such directionwill not by reason of so complying be deemed to havedeparted from the NPR.

Continuous Descent Approach (CDA)
For monitoring purposes, a descent will be deemed to havebeen continuous provided that no segment of level flightlonger than 2.5 nautical miles (nm) occurs below 6000ft QNHand ‘level flight’ is interpreted as any segment of flight havinga height change of not more than 50ft over a track distanceof 2 nm or more, as recorded in the airport Noise and Track-keeping system.
* The CDA data is broken down into four time periods, Day(0700hrs – 2300hrs), Night (2300hrs – 0700hrs), Core night(2330hrs – 0600hrs ) and the 06:00hr (0600hrs – 0700hrs)

Limits are set by the DfT
The regime applies to a night period (2300 – 0700 hours)during which the noisiest types of aircraft (QC8 and QC16)may not be scheduled to land or take off. In addition QC4types may not be scheduled to land or takeoff in the nightquota period (2330 – 0600).In addition, between 2330 –0600 hours (the night quota period) there are furtherrestrictions – the number of aircraft movements are restricted
by a movements limit and additionally there is a limit of noisequota points. These limits are set for each summer and winterseason. Neither of these limits may be exceeded, ie if themovements limit were to be reached, no further movementswould be able to take place even if quota points were stillavailable, and vice versa

Additional information
Information on noise is also available on the BAA Heathrowwebsite. This part of the website was updated in May 2007. Itincludes a flight tracking system called WebTrak which enableslocal residents to log on and view flight tracks for aircraftarriving at and departing from Heathrow. As well as beingable to track flights, WebTrak also gives details of the aircraft’sheight and position.
Noise complaints and enquiries may now be made from thewebsite. These facilities have been introduced to complementthe long-standing facilities so complaints/enquiries may still bemade by telephone or email (see right).
Updated statistical information on complaints and enquiries isnow included in BAA Heathrow’s Corporate ResponsibilityReport which is available in full on our website(www.heathrowairport.com/noise). A summary is availablefrom Heathrow Public Affairs, telephone 020 8745 5791.
Information on Noise Insulation and Noise and Blight Schemesis available in the BAA Heathrow Corporate ResponsibilityReport (see above).
