Night Noise (Arrivals) Respite Trials GATCOM Briefing 23/07/13

• Reminder of Key areas identified for respite

• Consultation Feedback Summary – Respondents list – Feedback comments • Clarifications from feedback received

• NATS Draft Trial Procedures

Suggested Key Areas for Night Noise Respite

The areas within this oval (primarily affected by arriving airrcaft during westerly operations)may need to be alternated for arrival respite to avoid moving noise to new areas Lodsworth (off map) to East or West of oval

The areas within this oval (primarily affected by arriving aircraft during easterly operation) may need to be alternated for arrival respite to avoid moving noise to new areas to East or West of oval

The areas within this oval may be possible to give longer periods without having to alternate arrival respite to avoid moving noise

Area Impacted by Key Altitude/Track Density

Low altitude/high density

Slide 3 High density

3 Higher altitude/ high density

Identified Areas for Night Noise Respite Highest priority has been given to those areas which are most densely over flown and at a lower height. Red areas indicate highest priority, amber 2nd highest priority and blue lowest priority. During westerly arrivals Tonbridge, Southborough, Markbeech, Penshurst, Pembury, Langton Green, Royal Tunbridge Wells, Fordcombe, Ashurst, Bells Yew Green, Frant, Crowborough, Mark Cross, Wadhurst, Ticehurst, Uckfield, Maresfield, Burgess Hill, Haywards Heath, Nutley, Newick

During easterly arrivals Billingshurst, Adversane, Coolham, Newpound Common, Roundstreet Common, Kirdford, Wisborough Green, Loxwood, Plaistow, Burgess Hill, Hurstpierpoint, Henfield, Haywards Heath

Consultation Feedback - Summary • No Alternation - 100% avoidance of population

• Use of academic independent body to advise/oversee

• Bidborough, Leigh, Chiddingstone Causeway (Penshurst Station), Hever should be included if possible or feedback why not - These are on final approach track for westerly arrivals and can’t be part of this trial (NATS) • Amber areas are as overflown and similarly at low level as red - therefore treat same or feedback why

• Explain why area chosen: give comparative number of flights or is there pop density threshold?

• Agree with most dense/low level - residential and hospital buildings should be priority for avoidance

• Need more info on impact to be able to comment on alternation

• Need clearer explanation on losers to justify winners

• Key areas proposed are correct

• Priorities correct

• Reduction of over flight for max number people is priority. No view on alternation. Should not increase flight time/Fuel burn/emissions. Must not compromise stable approach (unstable approaches lead to Go Around and more noise/fuel/emission

• Correct selection of areas - care required to avoid annoyance to other non-respite areas. Priority of red, amber, blue correct. Try to avoid cutting corners when turning onto ILS as other areas between ovals and ILS joining point could be overflown. Alternate on weekly basis to include one weekend. If arrivals modal operation changes during the week, it's alternative should be adopted for change of direction

• No opinions to offer as neither positive or negative impact on Horley - as too close to airport.

• A night ban is likely to be only respite option - we are not promoting this option at this time

Clarifications

• The trial is for night time use only.

• Feedback received regarding different priority for day time respite (such as schools – which are not occupied at night) are already recognised by GAL

• Density of over flight was one parameter used to determine key areas for respite – ‘heat plots’

• Highest priority of the key areas are generally in 60-200 over flight band – shown in yellow on heat plot diagram

Night Noise Respite/Reduction TRIAL

Proposed Night Noise Impact Respite/Reduction

Not below 5000’ B Lodsworth (off map) A Raised Descent Profile

Not below 6000’ Area Impacted by Key Altitude/Track Density

Low altitude/high density

Slide 9 High density

9 Higher altitude/ high density

Identified Areas for Night Noise Impact Respite/Reduction

Every Night of Trial No Arrivals Below 5000’ = Tonbridge, Lodsworth No Arrivals Below 6000’ = Crowborough, Mark Cross, Wadhurst, Ticehurst, Uckfield, Maresfield, Burgess Hill, Haywards Heath, Nutley, Newick, Hurstpierpoint, Henfield

During westerly arrivals Alternating Avoidance – No Arrivals Below 6000’ for Southborough, Markbeech, Penshurst, Pembury, Langton Green, Royal Tunbridge Wells, Fordcombe, Ashurst, Bells Yew Green, Frant, During easterly arrivals

Increased Descent Profile over Billingshurst, Adversane, Coolham, Newpound Common, Roundstreet Common, Wisborough Green, Kirdford*, Loxwood*, Plaistow*

* May be similar to current altitude, due proximity to final approach10 path

Next Steps

GATCOM members to confirm support for proposed solution

NATS to finalise the operational solution based upon agreement from GATCOM, including alternation timing (NATS needs 2 consecutive night intervals) and trial start date to be agreed

Operational trial ideally needs to commence BEFORE September GATCOM meeting
