Executive summary This report covers January to September 214. The period from January 214 to the end of Q3 has seen 68.73% westerly operations and 31.27% easterly operations. September alone saw a long period of Easterly operations at 52.88%. 1ft infringements are up on Q3 for 213 from 454 to 55. Of the 55 infringements to the 1ft requirement, 138 of these were below 9ft. Once again we continue to see fluctuations in the 1ft infringements due to high temperatures resulting in more infringements. Night noise infringements are once again down on this time last year. There have been 24 Night noise infringements to the end of Q3. 7 of these departing in the shoulder period between 23 and 233, and 17 departing after 233 when restrictions are at their tightest. There have been 8 Day Noise infringements for the period. This is the same figure as seen in the Q3 213 period. Flight Performance continues to provide noise data to British Airways Aircraft Performance Team for their A38 departures. Track Keeping All Runways has seen a small decrease in percentage on the same quarter last year. From Jan-sept 14 there have been 11269 deviations out of a total of 177452 departures resulting in a 93.65% compliance. CDA remains up on the same period for 213, with all four reporting periods showing improvement. Joining Point Night Lows continue to show improvement. Joining Point Day Lows are also improved in comparison to 213. However Day Lates and Night Lates are slightly higher than the figures for Q2 213. Late joiners are typically under tactical instructions from ATC, vectoring aircraft for operational reasons on the day. Summer 214 Night Quota and Movement figures continue well. The complaint callers have increased for the 214 Q3 period. The rise is this figure is due to a series of airspace trials taking place in 214 resulting in a large number of callers.

Caller = person Contact = number of times Enquiries = number of issues 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 Heathrow elevation and not sea level. References in the AIP are usually above sea level (quoted as Heathrow QNH) and therefore need to be reduced by 83ft to be comparable with heights as measured by ANOMS. No account is taken of the variability of heights as measured by the radar which, depending on the distance from the radar head can be +/- 2ft from that indicated. 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 AIRFIELD ELEVATION UNLESS OTHERWISE STATED. ALL DATA CONTAINED WITHIN THIS REPORT SHOULD BE CONSIDERED IN LIGHT OF THE PRECEDING TEXT AND COMMENT BOX THAT FOLLOWS. Page 4 Heathrow Airport Flight Performance Q3 Report 214

Departure Noise Limits AIP REFERENCE AD 2-EGLL-1-15 Subject to sub-paragraphs (5) and (6) below, any aircraft shall, after take-off, be operated in such a way that it will not cause more than 94 dba Lmax by day (from 7 hours to 23 hours local time) as measured by any noise monitoring terminal at any of the sites referred to in subparagraph (2*) above. Subject to sub-paragraphs (5) and (6) below, any aircraft shall, after take-off, be operated in such a way that it will not cause more than 89 dba Lmax by night (from 23 hours to 7 hours local time) and, that it will not cause more than 87 dba Lmax during the night quota period (from 233 to 6 house local time) as measured by any noise monitoring terminal at any of the sites referred to in subparagraph (2*) above. (5) The limits specified in sub-paragraphs (3*) and (4*) above shall be adjusted in accordance with the following table in respect of any noise monitoring terminal at any of the sites referred to in the table in sub-paragraph (2*) to take into account of the location of that terminal and it s ground elevation relative to the aerodrome elevation. (6) For the purposes of determining an infringement of the limits specified in sub paragraphs (3*) and (4*) above, if the aircraft was requested to take-off with a tailwind, an amount of up to 2dB of the noise recorded at the noise monitor should be disregarded. The amount to be disregarded shall be:.4 db for a tailwind of up to 1 knot..8 db for a tailwind exceeding 1 knot but not exceeding 2 knots 1.2 db for a tailwind exceeding 2 knots but not exceeding 3 knots 1.6 db for a tailwind exceeding 3 knots but not exceeding 4 knots 2. db for a tailwind exceeding 4 knots For this purpose, tailwind is to be calculated from the wind data measured in the on-air field anemometers and wind vanes according to the formula: (windspeed x cosine (runway heading minus wind direction))x-1 * AIP see glossary on page 3 Heathrow Airport Flight Performance Q3 Report 214 Page 7

Departure Track Keeping AIP REFERENCE AD 2-EGLL-1-17 For monitoring purposes, a departure will be deemed to have complied with the Noise Preferential Routeing (NPR) if, in the portion of flight below the appropriate vectoring altitude (see note 9 right), it is properly recorded by the airport s noise and trackkeeping (NTK) system as having flown wholly within the Lateral Swathe (LS). The LS is defined from the centre-line of the relevant route coded in the NTK system, based upon a map accredited for this purpose by the Department for Transport, by the closer to the centre-line depicted on the map of (a) a pair of lines either side, each diverging at an angle of 1 from a point on the runway centre-line 2m from startof-roll; and (b) a pair of parallel lines representing a distance of 1.5 km either side of the route centreline. For avoidance of doubt, the depicted route and LS may include curved sections representing turns. Note 9. Aircraft which have attained an altitude of 4 ft ( Heathrow QNH ) may be directed by air traffic controllers onto a different heading and commanders complying with any such direction will not by reason of so complying be deemed to have departed from the NPR.

In addition QC4 types may not be scheduled to land or takeoff in the night quota period (233 6).In addition, between 233 6 hours (the night quota period) there are further restrictions the number of aircraft movements are restricted by a movements limit and additionally there is a limit of noise quota points. These limits are set for each summer and winter season. Neither of these limits may be exceeded, ie if the movements limit were to be reached, no further movements would be able to take place even if quota points were still available, and vice versa Summary of allocation usage Winter 26 Summer 214 Season Seasons Seasons QC points Movements Total Total Total Movements Exempt Not Not Not Quota movements carried carried QC points movements QC against counted counted counted Points limit over over allowed allowed value limit Delays DfT Emergency Limit Winter 26 414. 255 28. 162 442. 2712 4266. 2659 95 311 2 Summer 27 561. 325. 561. 325 5235. 353 15 171 15 9 Winter 27 414. 255 374. 197 4514. 2747 41.25 271 87 178 6 44 Summer 28 546. 325. 546. 325 4634 2922 19 116 3 12 Winter 28 411. 255 826. 328 4936. 2878 3947.5 2715 8 26 4 32 Summer 29 546. 325. 546. 325 4429.25 2848 18 45 3 7 Winter 29 411. 255 437. 325 4547. 2875 3863.25 2686 11 32 3 21 Summer 21 534. 325. 534. 325 454.75 333 12 56 134 9 Winter 21 411. 255 572. 217 4682. 2767 3735.25 2577 67 185 16 37 Summer 211 522. 325 522 325 4491 2958 116 75 1 25 Winter 211 48 255 759 292 4839 2842 3374.5 2581 75 71 73 Summer 212 51 325 51 325 3946.25 2853 72 118 11 26 Winter 212 411 255 51 325 462 2875 331.75 267 26 19 2 51 Summer 213 51 325 51 325 3917. 2837 43 143 2 18 Winter 213 48 255 48 26 4488 281 37.5 2715 26 89 11 71 Summer 214 51 325 * Carry over see glossary on page 3 Page 2 Heathrow Airport Flight Performance Q3 Report 214

Additional information Information on noise is also available on the BAA Heathrow website. This part of the website was updated in May 27. It includes a flight tracking system called WebTrak which enables local residents to log on and view flight tracks for aircraft arriving at and departing from Heathrow. As well as being able to track flights, WebTrak also gives details of the aircraft s height and position. Noise complaints and enquiries may now be made from the website. These facilities have been introduced to complement the long-standing facilities so complaints/enquiries may still be made by telephone or email (see right). Updated statistical information on complaints and enquiries is now included in BAA Heathrow s Corporate Responsibility Report which is available in full on our website (www.heathrowairport.com/noise). A summary is available from Heathrow Public Affairs, telephone 2 8745 5791.
