I see that an early report has gone to the Aviation Minister. It is interesting that they want to know what a successful engagement with the commmunity would look like (for the next phase).

The section on how they should measure noise impacts is interesting (pages 25 - 29), but the early illustrative map of changes in noise for out of alternation arrivals on 27R due to TEAM* in Nov/Dec (Fig 6.1) might suggest that Brentford doesn't have a problem !

The executive summary concludes with :


CAA recommendations

 Any adjustments to the trial design and trial methodology should be agreed between the DfT, CAA and BAA further in advance of the planned commencement of the second phase of the trial to enable better preparation and greater transparency.

 A key step in the data validation process for the final report will be ensuring that the two principal sources of data used in measuring use of the trial freedoms (i.e. the Noise and Track-Keeping System and NATS operations logs) are reconciled accurately and consistently so as to provide a robust and reliable picture of the flights that have benefited from the application of the operational freedoms. We would recommend that Cambridge University look specifically at this aspect of data generation as part of their validation role.

 We note that the timing of the first phase of the trial allowed only limited opportunity for prior engagement with local communities. We recommend that BAA considers how best to engage with communities about the trial ahead of the commencement of the second phase, including seeking agreement with the DfT and CAA on what successful engagement looks like.

 Local authority technical experts should have more, and earlier, opportunity to be engaged in the data verification and analysis.

 The publication of existing runway operating procedures in mid-December helped to answer a number of the questions raised about the distinction between pre-existing procedures and the operational freedoms in the trial. We recommend that the differences between existing flexibility and the freedoms being tested by the trial are clearly explained at an earlier stage for the second phase of the trial.
