Gatwick Airport Flight Performance Team

Quarterly report for the period July to September 2012

About Gatwick Airport

Gatwick Airport opened in 1958 with just over 186,000 passengers passing through in our first year of operation. Today, it's a different story. We're open 24 hours a day, 365 days a year, and we now serve almost 34 million passengers every year.

Gatwick is one of the top ten international airports in the world and the second largest in the UK. Around 90 carriers operate from the airport including British Airways, easyJet, Emirates, Monarch Airlines, Thomas Cook, Thomson Airways and Virgin Atlantic. It is the best connected point-to-point airport in Europe welcoming almost 33.8 million passengers (March 2012) a year flying to more than 200 destinations.

The airport is 28 miles south of London with excellent public transport links. Gatwick Airport is owned by a group of international investment funds, of which Global Infrastructure Partners (GIP) is the controlling shareholder. Over the next 10 years we want Gatwick to become London’s airport of choice delivering great service to more than 40 million passengers each year.

Security, safety and responsibly managing our environmental impact are always our top priorities.

About this report

This report is produced by the Gatwick Flight Performance Team (FPT). This team is responsible

for recording, investigating and responding to aircraft noise enquiries as well as monitoring airline

compliance to noise mitigation measures as detailed in the UK Aeronautical Information

Publication (AIP). This department also actively engages with the airlines to improve their

adherence to the above noise mitigation measures and in addition manages the night-time

restrictions on flying at Gatwick.

This report contains detailed data on aircraft activity at Gatwick including the adherence to the

noise mitigation measures detailed in the UK AIP, a report on night flying during the quarter, an

update on the community noise monitoring programme and an analysis of complaints / enquires

received during the period.

Flight Performance Team commentary

A final summary report of the temporary noise group was presented to NATMAG for discussion,

and at this time there are no plans for any further meetings of this particular group. The report

highlighted key areas of discussion and some possible options for moving forward, which will of

course be progressed through the appropriate governance structure.

A report on approach noise at Gatwick, produced by the Gatwick Area Conservation Campaign

was also discussed at the last NATMAG. Gatwick Airport has committed to providing responses to

the issues and suggestions raised in that report.

Performance Headlines

Over a 12 month average, the Continuous Descent Approaches (CDA) indicators for all time

periods have turned red. The primary reason for the drop in CDA performance is due to the the

main runway being out of operation from 21:30 each night whilst runway resurfacing continues

throughout 2012. It is expected that the night-time achievement rate will indeed remain lower than

its recent average until the main runway resurfacing works are completed. These works will be

happening during the night time, when the Northern runway will be utilised. Because of the

absence of descent profile guidance from an ILS this necessitates a phase of level flight prior to

the initiation of Ground Control Approach by Gatwick Air Traffic Control. Even so in the last 3 years

the 12 month average has increased from 80% to the current level of around 90%. On a positive

note the drop in performance this year is significantly less than that experienced when the runway

was last resurfaced in 2000. The FPT continues to work with airlines on improving their

performance with regular reviews and data gathering exercises.

Track keeping performance has shown another small improvement on the previous year’s

performance. It should be noted that some Gatwick departure routes have turns of 90⁰⁰ and 180⁰

which, when they were first designed, were easier to fly with older, slower aircraft, although they

remained lower on the route for longer. Track deviations occur on all routes. However at Gatwick

Airport the 26 Lambourne wrap around route has the largest proportion. Further details on track

keeping will follow later in this report.

As part of our continuing commitment to increase on track performance the FPT also continues to

engage with the airlines directly and through the Flight Operations Performance and Safety

Committee on a range of initiatives.

The number of enquiries has reduced considerably compared to the previous twelve months with a

reduction of over 30%, although at the same time the number of callers to the Flight Performance

Team has increased by 12%.

3

The postcode areas with the greatest number of complainants this quarter were, East Grinstead,

Edenbridge (which includes surrounding villages), Horley and Crawley.

Airport Operations

During the quarter, there were a total of 72,936 fixed wing aircraft movements at Gatwick, almost

exactly the same as in the same period in 2011. The direction of operation is determined by wind

direction and this quarter was split 86% on the westerly runway and 14% on the easterly runway.

The poor summer weather dominated by Atlantic weather systems contributed to the unusually

large percentage of westerly operations this quarter.

Northern Runway (26R/08L) usage

During these three months there were a total of 7258 movements from the northern runway. The

northern runway is normally only utilised during the night when maintenance on the main runway is

planned, however the main runway is being rehabilitated during 2012 and 2013. These works

commenced in March 2012 and are due to be finalised in October, and will require extensive

periods of northern runway operations during the night time period. Although Gatwick has a main

runway and the ‘reserve’ northern runway, they cannot be operated simultaneously.

Complaint response time

This quarter the percentage of enquiries that have been responded to within 8 days was 95.41%. A

full breakdown of complaint information is produced later in this report.

Airline Communications

The Flight Operations Performance & Safety Committee (FLOPSC) meets bi-monthly. At these

meetings performance statistics in relation to the 1000ft by 6.5km from start of roll (SOR)

requirement, departure track keeping, departure noise infringements, and CDA statistics are

routinely discussed.

As part of our normal process the FPT sends details of track deviations to the appropriate airline so

those details can be passed on to the relevant training captain or chief pilot so they can work with

their flight crews to improve future performance. As part of our ongoing work with the airlines and

NATS at FLOPSC, there has been increased uptake in the number of departing flights being

granted PRNAV departures, which should in turn have an overall positive effect on departure track

keeping performance. The FPT will continue to monitor PRNAV uptake.

The Airline performance statistics relating to both track keeping and CDA achievement are now

being circulated to a much wider airline audience each month. This includes all domestic airlines

and the majority of foreign operators. As part of our ongoing work in this area the FPT are working

to ensure that all new airlines are acquainted with the noise abatement rules and are made aware

of our published Arrivals Code of Practice.

The FPT endeavours to send details of all track deviations or unusual activity to the appropriate

airline and frequently receives welcome feedback on measures employed by them to reduce

4

further reoccurrences. The FPT also offers to work with airlines to improve their track keeping at

FLOPSC meetings.

The issue of weather deviations passing over Crawley town was recently discussed at the request

of NATMAG as there were some concerns that these events could be avoided. After discussion

with the pilots represented it was determined that only after an aircraft was lined up on the runway

could its weather radar accurately map in 3 dimensions potential storm conditions ahead. The

weather radar available to ATC does not have this advanced capability and therefore cannot

predict if it is possible for a departing aircraft to navigate a route under or over a storm activity.

Community Noise Monitoring

The Gatwick Noise Monitoring Group is a forum where Local Authority technical experts and

independent consultants meet with Gatwick Airport Ltd to discuss the location of mobile noise

monitors, the duration they are to be onsite and to review and verify the data. This group also

makes recommedations on monitor locations and also on the format the data should be reported to

the Noise & Track Monitoring Advisory Group (NATMAG) and the wider community. Mobile noise

monitors are deployed at sites in Lingfield, Rusper, Okewood Hill, Leigh, Haywards Heath,

Rudgewick and Blindley Heath. The inactive monitor that has been located at Hever for a number

of years was recovered this quarter and following a service and calibration will be available for

deployment. The monitors at Leigh and Haywards Heath are due to be relocated in the next couple

of months.

Sustainable Aviation

Gatwick Airport Ltd is a member of Sustainable Aviation. This is a long term strategy which sets out the collective approach of UK aviation to tackling the challenge of ensuring a sustainable future for our industry. Sustainable Aviation was launched in 2005 and brings together the main players from UK airlines, airports, manufacturers and air navigation service providers

The FPT Manager is a member of the Sustainable Aviation Improvements Group. The ‘mission statement’ of this group is “Working with the industry in the UK and internationally to trial & implement innovative low noise and emission procedures”.

After a long period of development the ‘Departures Code of Practice’ (DCOP) was launched at the end of June at an event in London attended by members of Sustainable Aviation including Gatwick airport. The basis of this voluntary code of practice are four primary mitigation techniques to reduce the environmental impact of aircraft on the ground and departing flights. These are to reduce the frequency and length of auxiliary power and ground power unit running, which both use more fuel than fixed electrical power and create noise on the ground. Secondly to encourage aircraft to use reduced engine taxiing when safe and appropriate to do so, which will save fuel and reduce Carbon and Nitrous gas emissions. Introduce Airport – Collaborative Decision Making (A-CDM) which, which will improve the efficiency of aircraft moving about the airfield and en route. And finally to introduce Continuous Climb Operation for departing aircraft which will reduce fuel consumption as aircraft reach their optimum cruise altitude quicker were jet engines are more efficient. For more information visit: www.sustainableaviation.co.uk

The DCOP has been formally adopted by the by the Gatwick airline community who have signed up in principle to its commitments. Work continues on some aspects of the code, including a new tool to monitor continuous climb operations.

Community Communications

The END noise action plan was formally adopted by the Secretary of State on 19th May 2011. The action plan details 50 plus actions that the airport will deliver during the period covering 2010 - 2015. We have already been active in delivering against the 2010 actions proposed and are therefore well on schedule with our plan. Progress will be reported through our S106 annual monitoring report as the END noise action plan will replace our S106 interim noise action plan. A PRNAV Consultation paper was published in July 2012 which describes our proposal to replicate, implement and eventually replace, within the next five years, the current standard departure routes from Gatwick Airport The Head of Corportate Sustainability Gatwick Airport has arranged several meetings with local communities to inform them of the Consultation and answer questions. Representatives from NATS have also attended these meetings, many of which have been well attended. This is an example of Gatwick’s on going policy of engaging with the local community on potential impacts of Gatwick’s operations. The consultation paper is available for download at http://www.gatwickairport.com/prnav

WebTrak

Gatwick Airport Limited offers a web based flight tracking application called WebTrak. This facility

allows members of the public to track Gatwick flights. An updated version was released in 2010

and was designed to be more user friendly, with a number of additional enhancements that

improves on the look and feel from the original. Since its introduction this has proven to be very

popular and a useful tool for communities affected by noise. Details of the number of WebTrak hits

are shown on the following page. Recently the fixed noise monitors on this site have been

activated so they now show the maximum noise reading (LMax) of flights as they pass close to a

monitor. Please visit www.gatwickairport.com/noise

Complaints Handling Policy

The noise complaint handling policy established in December 2008 and amended in May 2010

continues to be applied consistently by the FPT when dealing with noise related enquiries. This

policy is displayed on the Gatwick Airport noise website.

http://www.gatwickairport.com/business/noise/noise-enquiry/contact

In order to provide a co-ordinated and accurate response to complaints, the FPT continues to

engage actively with colleagues within NATS, the CAA, DfT and other organisations when dealing

with noise related enquiries.

Gatwick Airport Noise Website

The Gatwick Airport Noise Website has recently undergone a review by a website design company

to make it more accessible and user friendly to the general public. The website provides detailed

maps on aircraft traffic around the airport as well as useful information on noise and statistics on

aircraft movements. Links provide access to community noise monitoring reports written by our

independent noise consultant and reviewed by the Gatwick Noise Monitoring Group, as well as

access to FPT annual and quarterly reports, including for the first time annual airline Continuous

Descent Approach performance statistics.

The Aeronautical Information Publication

An Aeronautical Information Publication (or AIP) is defined by the International Civil Aviation

Organisation (ICAO) as a publication issued by or with the authority of a state and containing

aeronautical information of a lasting character essential to air navigation.

It is designed to be a manual containing thorough details of regulations, procedures and other

information pertinent to flying aircraft in the particular country to which it relates. It is usually issued

by or on behalf of the respective civil aviation administration.

The structure and contents of AIPs are standardised by international agreement through ICAO.

AIPs normally have three parts - GEN (general), ENR (en route) and AD (aerodromes).

The Gatwick Aerodrome AIP contains details regarding the noise mitigation measures in place and

adherence to these is reported in this section.

Adherence to noise mitigation measures as detailed in the Gatwick AIP

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 mean sea level and the ANOMS NTK system

measures height relative to Gatwick elevation and not sea level.

8

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 THE COMMENTARY THAT FOLLOWS.

DEPARTURES - INITIAL CLIMB PERFORMANCE

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.

Comment:

There were no infringements of the 1000ft rule during this quarter.

Historically the summer months are typically the peak period for aircraft failing to meet the 1,000ft

requirement primarily due to the warmer weather, which reduces aircraft climb performance.

DEPARTURES - TRACK KEEPING

All jet aircraft leaving Gatwick Airport should follow flight paths known as Noise Preferential Routes (NPRs) up to a height of 3,000ft or 4,000ft depending on the route. NPRs were set by the Department for Transport (DfT) in the 1960s and were designed to avoid over flight of built-up areas where possible.

They lead from the runway to the main UK air traffic routes, and form the first part of the Standard Instrument Departure routes (SIDs). The routes have not been altered since they were established in order to give people the predictability of knowing where noise from departing planes will be heard. Their location remains the responsibility of the Government. As an airport operator, Gatwick Airport Ltd has no authority to change them. Any significant changes to the NPR’s would be subject to a public consultation exercise.

Air Traffic Control (ATC) are responsible for the routing of aircraft once airborne and when 3,000 or

4,000ft has been reached they may give a flight a more direct heading (known as vectoring) off the route.

This is subject to certain factors including weather conditions or other traffic in the vicinity.

An NPR is not narrow, as aircraft cannot fly in the same way a train runs on a track, so each route has a

‘swathe’ measuring 1.5 kilometres either side of the route centreline, resulting in a corridor 3 kilometres

wide. As long as aircraft remain within this ‘swathe’ they are deemed to be on track, there is no

requirement to follow the route centreline.

11

Any flight leaving the route below the required height (a track deviation) is automatically tagged by a

Noise and Track Keeping System in the Flight Performance Team at Gatwick Airport. Details of all track

deviations are supplied to our Flight Operations Performance & Safety Committee and discussed at their

bi-monthly meetings.

Comment: The table below shows track keeping performance over the previous 12 month period.

Compared to the second quarter 2012 the on track performance has fallen from 97.94% to 96.34% over

the past three months. For the rolling 12 month year on year period the on track performance stands at

97.54% as opposed to 97.359% for the 12 months ended September 2011.

HORLEY GATE PENETRATION GRAPH

Comment:

NATS implemented a plan in 2010 to reduce such incidents. Air Traffic Controllers were reminded that no flights should over-fly Horley. They also made changes to the standard routings for aircraft positioning from London Heathrow to Gatwick in order to avoid over-flight of Horley. The FPT continues to monitor and report this so that performance can be monitored and improved over time.

The jet aircraft with the lowest recorded height was a JU 213 Boeing 737 over-flew the town at a height of 3996ft above airfield elevation. The average height of Gatwick aircraft passing over the town was 7088 ft.

ARRIVALS – CONTINUOUS DESCENT APPROACHES (CDA)

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.

17

CDA data is measured over three time periods, the core night period (2330-0600), the day and

shoulder periods (06:00 – 2330) and the 24hour period.

CORE NIGHT PERIOD

Comment:

During the quarter the core night-time CDA achievement rate was 84.89%, a small increase from

84.79% recorded in the previous quarter. The closure of the main runway to allow resurfacing would

appear to have had a major effect on the CDA performance rate, especially during the night. The main

runway has been closed most nights from 21:30 to 04:30. This effect was also apparent when the main

runway was resurfaced over 10 years ago. The 12 month rolling average for night time achievement is

now 86.55% of all arrivals. This compares with an average achievement rate for the preceding twelve

month period ended September 2011 of 93.76%. As the major runway rehabilitation has been completed

we expect to see an improvement in the night time CDA performance.

ARRIVALS – OVER CONGESTED AREAS

AD 2-EGKK1-12 (11)

Before landing at the aerodrome the aircraft shall maintain as high an altitude as practical and shall not fly

over the congested areas of Crawley, East Grinstead, Horley and Horsham at an altitude of less than 3000ft

(Gatwick QNH) nor over the congested area of Lingfield at an altitude of less than 2000ft (Gatwick QNH). NB. 2000 ft – (202ft (airfield elevation) + 100ft (radar/ILS tolerance)) = 1698ft on ANOMS.

Comment:

Aircraft tracks were analysed for July, August and September 2012 and except for several go-arounds there

were no over-flights of Crawley, Horley or Horsham under 3000ft.

A gate at 7 nautical miles (nm) from touchdown is used to analyse tracks over the Lingfield area. There

were 32 (or 0.10%) of westerly arrivals passing through the 7nm gate during the quarter that were greater

than 1000ft lower than 2000ft (this equates to a height in ANOMS of 1698ft see below) The lowest recorded

height at 7nm on ANOMS was 1,581ft.

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.

A) Day time joining height (0600 – 2330)

22

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 36,460 arrivals

recorded by ANOMS this quarter, 57 (0.16%) of which were operating below an altitude of 2000ft

(equivalent to a height in ANOMS of 1798ft) through one or more of the analysis gates. There were 21 ‘go-

arounds’ that were included within the total of 57, although for the sake of clarity these tracks are not

included in the map illustrated. Of the 36 arriving flights that were not ‘go-arounds’ 25 were more than 100ft

below the altitude of 2000ft.

MAP ILLUSTRATING THE ANOMS LATE ANALYSIS GATES WITH URBAN AREA ANNOTATED

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.

23

B) Night joining height & distance

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.

JOINING POINT GRAPH

GO - AROUNDS

A go-around is a procedure adopted when an arriving aircraft on final approach aborts landing by applying

take off power and climbing away from the airport. It is a set procedure to be followed by the flight crew in

the event of an aircraft being unable to land. The procedure is published so that Air Traffic Control (ATC)

and the pilots can anticipate where the aircraft will go following the decision to go-around.

24

The number and reasons for go-arounds are routinely discussed at FLOPSC 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 in and are familiar with.

Gatwick Airport Ltd as the airport operator actively encourages airlines operating at the airport to fly to the

best possible environmental standards. However safety must and always will be the number one priority.

NATS currently record go-arounds under one of the following causal factors:

Comment: During July to September there was an unusually large number of go arounds (41) that

occurred during the night period, which is generally much less busy than during the day time. The utilisation

of the northern runway during this time is likely to have been a contributing factor.

NIGHT FLIGHTS

Introduction

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 may take off or

land.

The night flying restrictions are divided into summer and winter seasons which coincide with the start and

end of British Summer Time. They consist of a movement limit and a quota count system. The quota count

(QC) means that points are allocated to different aircraft types according to how noisy they are. The noisier

the aircraft type, the higher the points allocated. This provides an incentive for airlines to use quieter aircraft

types. Aircraft are certified by the International Civil Aviation Organisation according to the noise they

produce and are classified separately for both take off and landing

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), where other restrictions apply to the scheduling and operation of aircraft of specified

descriptions

Comment:

The summer season 2012 began at 01:00 hours 25th March 2012, and the season limits are 6200 QC points and 11,200 movements. The end of season report produced for the Department of Transport is shown in the table on the following pages outlining the weekly movement and QC usage to date. In summary the airport utilised 87.2% of the movements limit and 79.9% of the quota count limit.

26

The Department for Transport has confirmed that the current night flight restriction will remain in force until

October 2014, with a consultation to be launched next year.

Dispensations - There have been no dispensations during the summer 2012 season.

QC4, QC8 and QC16 movements

There have been no QC8 or QC16 movements during either the ‘night quota’ or ‘shoulder periods’, and no QC4

movements during the ‘night quota period’.
