Flight Evaluation Unit Update Performance Headlines The full Flight Performance report contains detailed statistics and commentary in relation to aircraft noise issues. Set out below are a number of summary headlines: February was unusual in that there appears to have been a large number of deviations when the airfield was operating in an easterly direction. The reason behind this relates to the use of the northern runway during the day time following the spillage incident mentioned previously. Because the NPR corridors in the ANOMS system has been designed to align with the main runway, aircraft departing on the Northern can sometimes be counted as ‘off track’ when the first radar plot appears before the aircraft enters the NPR corridor. On this particular day 35 aircraft where counted as ‘off track’, when in reality they did not deviate from the NPR. These deviations accounted for 20% of the all the ‘off tracks’ in February. From 1st October 2008, all prop and weather vectors are now included within the statistics. Not only does this bring Gatwick in line with the other SE Airports, it also more accurately reflects what is experienced by the local community. Prior to October 2008 propeller driven aircraft, weather diversions and those that had been vectored by NATS were not included within the track deviation statistics. No noise infringements of either the day-time or night-time limits were recorded during the first quarter of 2009. On a rolling year average, all the CDA indicators are showing improvement which is positive direction for Gatwick. The winter nightquota period ending March 2009, has seen a drop in the number of operations compared to the previous winter. This overall drop in traffic corresponds to trends in reduced air traffic as the recession continues. Noticeably there was a marked reduction in the number of QC 0.25 movements during the night period compared to the previous year. Because the number of movements for other aircraft remained relatively stable, this showed up as an increase in percentage terms of the movements of other types, especially QC 0.5 which jumped from under 30% to 40%. When examining the possible reasons behind these figures it was noted that in 2007/8, GB Airways had 641 night-time movements, but none in 2008/9. The fleet being operated were Airbus A320s and A321s, which are both QC 0.25 on arrival. Although some of these operations were incorporated into Easyjet which previously also operated an exclusive fleet of A319s, also QC 0.25 on arrival, it is apparent that combined the usage of EZY/ GBL reduced from 984 movements (2007/8) to 432 (2008/9) and this would appear to be the major contributing factor to the change. Airline Communication This quarter the FEU contacted 25 airlines regarding poor track keeping. Additionally 6 airlines currently receive feedback and data on their CDA performance. In the coming months it is our intention to focus again on the larger airlines at Gatwick who are not performing as well as others, and to re-engage those that have seen a drop in performance after previous gains. The Airline performance statistics relating to both track keeping and CDA achievement are now being circulated to a much wider airline audience each month, which include all domestic airlines, and the majority of foreign operators. Work continues to ensure that we are able to circulate these statistics to all airlines that operate at Gatwick. The Flight Operations Performance Committee (FLOPC) met once during the quarter during which performance statistics in relation to the 1000ft by 6.5km from start of roll (SOR) requirement,

of 25

departure track keeping, departure noise infringements, CDA and complaint statistics were discussed. This committee now meets every two months, instead of each month. Community Communications The noise complaint handling policy which was rolled out in December 2008 continues to be adhered too with any long-standing or persistent complainers. The regular caller from Hever has also been advised that we intend to remove the noise monitor from his property, which has been in situ for over 3 years. A report has been prepared using data collected by the noise monitor and analysed by AAD. The report additionally considers data taken from BAA’s Airport Noise Operations Monitoring System, which has been analysed to ascertain the current situation relating to the number and height distribution of aircraft passing through the Hever analysis gate. It is intended that this report will be forwarded to the complainant at the time that the monitor is removed. FLIGHT PERFORMANCE REPORT

DEPARTURES 1. Initial Climb performance

DATA:

EGKK AD 2.21 (3(1)). After take-off the aircraft shall be operated in such a way that it is at a height of not less than 1000 ft aal (above airfield level) at 6.5 km from start of roll as measured along the departure track of the aircraft. This is to ensure departing aircraft achieve at least that climb gradient in order to reduce the impact on the ground.

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 Gatwick is 202ft above sea level and the ANOMS NTK system measures height relative to Gatwick elevation and not sea level. References in the AIP are usually above sea level (quoted as Gatwick QNH) and therefore need to be reduced by 202ft to be comparable with heights as measured by ANOMS. For example the requirement to join the ILS at 3000ft would equate to 2798ft in the 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 +/- 200ft 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.

Comment: The summer quarter is typically the peak period for aircraft failing to meet the 1000ft requirement primarily due to the warmer weather and peak in traffic and passenger numbers. The majority of the aircraft which fail this requirement are Gatwick tend to be smaller propeller driven types. 2. Departure Noise Limits a) Daytime Limits

EGKK AD 2.21(3(3)) 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 0700 to 2300 hours local time) as measured at any noise monitoring terminal at any of the sites referred to in sub-paragraph (2). This is to ensure that departing aircraft do not exceed the stated level during the day.

Comment: The percentage of departures that deviated from the NPRs in the three months ending 31 March 2009 was 2.09%* compared with 1.45% for the equivalent quarter of 2008. The percentage of deviations for the last 12 month period ended 31st March 2009 was 1.69%* and the corresponding previous 12 months ended March 2008 was 1.40%. *Prior to October 2008 propeller driven aircraft and those that had been vectored by NATS were not included within the track deviation statistics. From this date any aircraft that deviates from the NPR below the required altitude have been included as this more accurately reflects what is experienced by local communities. *If props were excluded this figure would have been 1.36%. 4. Departures over Congested Areas a) 26WIZAD Departures at Night

Comment: There were no night time departures on the 26WIZAD NPR during this quarter. The FEU has been in contact with ATC regarding this issue and have received a copy of an ATC notification reminding all controllers of this particular requirement. b) Overflight of Horley and Crawley

Comment: There were 26999 departures in this quarter of which 7112 were on the NPR 26LAM. Analysis gates have been established over the Horley and Crawley areas. For Horley this shows the average height to be 7210 ft with the lowest jet aircraft at 4020ft. Of the 258 passing through the Horley gate 19 were below 5000ft. Over the quarter the average percentage of 26LAM departures passing through the Horley gate was 3.63%. During the same period there was one departure that passed over Crawley town, Virgin Atlantic flight VS033 on 17/01/2009, departing at 09:43. This 747-400 departed on runway 26L and was vectored south of the normal departure routes because of adverse weather conditions; it passed just west of Crawley at a height of 2713, as per the track map below.

Percent of CDA Achievement

EGKK AD 2.21 (10) Where the aircraft is approaching the aerodrome to land it shall commensurate with it ATC clearance minimise noise disturbance by the use of continuous decent and low power, low drag, operating procedures (referred to in Detailed Procedures for descent clearance in AD (2-EGKK-1-17). Where the use of these procedures is not practicable, the aircraft shall maintain as high an altitude as possible. In addition, when descending on initial approach including in the closing heading, and on intermediate and final approach, thrust reductions should be achieved where possible by maintaining a 'clean' aircraft configuration and by landing with reduce flaps, provided that in all the circumstances of the flight this is consistent with safe operation of the aircraft. This is to avoid prolonged periods of level flight and keep aircraft as high as possible for as long as possible.

DATA: The CDA data is broken down into three time periods, core night (2330-0600), Day & shoulder (0600-2330) and the whole 24 hour.

Comment: During the quarter there has been a deterioration in the core night-time CDA compliance rate however year on year, the compliance rate was 89.97% for the period April 2008 – March 2009 compared with 89.1% for the preceding twelve months ended March 2008.

6. Arrivals over congested areas Comment: Tracks were analysed for January, February, and March 2009 and other than a small number of go arounds, there were no arrivals below 3000ft over the towns of Crawley, Horley, Horsham or East Grinstead. A gate at 7 nautical miles (nm) from touchdown was used to analyse tracks over the Lingfield area. There were 28 or (0.15%) of westerly arrivals passing through the 7nm gate during the quarter that were greater than 100ft lower than 2000ft (this equates to a height in ANOMS of 1698ft see below). The lowest recorded height at 7nm on ANOMS was 1473ft. NB. 2000 ft – (202ft (airfield elevation) + 100ft (radar/ILS tolerance)) = 1698ft on ANOMS.

7. ILS Joining Point

a) Day joining height

Comment: The map shows those arrivals that have passed through at least one of a series of gates running parallel to the runway centreline for around 6nm east and west of the airport below 2000ft. There were 27034 arrivals during this quarter of which 39 (0.14%) were operating below an altitude of 2000ft (equivalent to a height in ANOMS of 1798ft) through one or more of the analysis gates. Of these flights, 15 were more than 100ft below. It should be noted that 15 go arounds were included within the total of 39, although for the sake of clarity these tracks are not included in the map above.

EGKK AD 2.21 (13 (a)) Where the aircraft is using the ILS in IMC or VMC it shall not descend below 2000 ft (Gatwick QNH) before intercepting the glide path, nor thereafter fly below the glide path. This is aimed at keeping aircraft as high as possible for as long as possible.

Percentage

% Joining at less than 10nm

% Joining below 3000ft (measured to 2598ft )

% Joining below 3000ft (measured to 2798ft )

Comment: ANOMS was introduced in June 2007 and this corresponds to the rise in aircraft joining below 3000ft, however this was not the reason. Previously only aircraft below 2598ft at 10nm would have been recorded which takes account of the 202ft elevation of Gatwick and the 200ft tolerance of the radar equipment. This metric is primarily used by NATS to ensure compliance and in allowing for these tolerances it is reasonable for a controller to assume that if an aircraft displays an altitude of 2800ft on their system it is compliant with the 3000ft requirements. The same aircraft would be at 2598ft above the airfield as displayed on the Gatwick ANOMS (or any NTK) system. Since June 2007 statistics have only taken account of the airfield elevation and consequently any aircraft below 2798ft at 10nm has been flagged. 8. Go Arounds

EGKK AD 2.21 (14) Between the hours of 2330 (local) to 06:00 (local), inbound aircraft, whether or not making use of the ILS localiser and irrespective of weight or type of approach, shall not join the centre-line below 3000ft (Gatwick QNH) closer than 10 nm touchdown. This aims to keep aircraft higher for longer and avoid overflying areas en route to the ILS below 3000ft.

2009* 98 27034 0.36 * Data up to 31 March 2009 Comment: The number and reasons for go-arounds are routinely discussed at FLOPC meetings and Pilot Forums. All parties are focussed on minimising the number of occasions when a go around is required but expect some to occur given the fact that Gatwick is a busy single runway airport. It should be stated that there are well established standard procedures which both pilots and controllers are trained and familiar with. This quarter the most common reasons for go-arounds were ‘unstable approach’ (33), runway occupied’ (29) and ‘aborted take off’ (10). NOISE MONITORING 9. Community Noise Monitoring DATA: Following feedback from a previous report it is proposed that detailed data relating to the mobile monitoring locations be summarised on a less frequent basis. Comment: There are currently 4 monitors located around the Gatwick area which form part of the community noise monitoring program first established in the late 1990s and featuring as a commitment in the original Sustainable Development Strategy. The monitor that was located in the Charlwood village was recently removed at the request of the landowner. Data collected and analysed from these sites is discussed regularly between BAA Gatwick, Local Authority technical experts and independent consultants. Trends over several years have been monitored and reported to NaTMAG. Long term trends in Leq have remained relatively constant over the past few years and the most recent results do not show any distraction from this. Lmax data is also tracked and the ANOMS system has enabled some greater resolution of this data for each site. In addition to the four monitors detailed above there are two monitors in the Capel and Hever areas which have also been in situ for prolonged periods. It is proposed that these monitors will be removed and, following discussions at a recent EHO meeting, two new sites have been agreed for

From time to time, it is necessary for an aircraft to abort its landing – a procedure known as a go-around. The loss of an anticipated runway slot is the most common reason for a go-around. The closure of the main runway can impact on the number of go-arounds. There are established procedures to manage a go-around

the positioning of these monitors. One site is to the north of Horley and the second at Slinfold. Both sites are primarily departure sites. 10. Night Flights

The Secretary of State in exercise of his powers under Section 78 of the Civil Aviation Act 1982 has imposed restrictions at Gatwick airport on aircraft operating at night. These restrictions are in place to limit and mitigate noise disturbance from aircraft operating at night and to prohibit aircraft of specified descriptions from operating, also to limit the number of occasions on which other aircraft make take off or land. For the purposes of night flying operations, the night quota period is defined as the period between 23:30 and 06:00 (Local time). In addition there are two further shoulder periods of 23:00 - 23:30 and 06:00 – 07:00 (Local time), were other restrictions apply to the scheduling and operation of aircraft of specified descriptions.

Comment: The winter 2008-09 season began on 26 October 2008 and ended on 28 March 2009 (22 weeks). The quota limit for the winter season was 3250 movements and 2180 QC (quota count) points. Data for the winter mid season update is included in the following tables/commentary: Dispensations There were no dispensations during the winter 2008-09 season. Update on QC4, QC8 and QC16 movements There were no QC4, QC8 or QC16 movements during the winter 2008-09 season, including the shoulder periods. Summary Below is a graph showing a historical comparison of aircraft movement and QC usage during winter nightquota period 2000/1 – 2008/9. There is a copy of the Dft report for the Winter 2008/9 season, which shows a summary of all movements by week, and QC value. Also included in the report are details of exempt flights and data on the percentage of arrivals and departures by week. A table showing the comparison of QC usage between 2007/8 and 2008/9 seasons is also shown.
