The monthly report for January has yet to appear (and is thus rather delayed compared with those for November and December which appeared around the 22nd of the following month). Perhaps some additional screening work is going on before publication.
Going on to the second phase of the trials (if the Minister is minded to pursue them), the CAA have recommended better and earlier discussion with the local authorities and other stakeholders :
Recommendations:
(a) 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.
(b) We recommend that local authority technical experts should have more, and earlier, opportunity to be engaged in the data verification and analysis.
(c) 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.

ACL have also written to airlines regarding the reduced declared capacity for the Olympic period
Specifically for the period 14th July to 14th September inclusive, Heathrow is declaring a revised scheduling limit for both runway arrivals and departures, and for terminal load factors.
They also request that night time operations be avoided
The purpose of the trial is to provide an evidential base for future operating permissions whose outcome will be the reduction in delay, improvement in punctuality and increased resilience of the ATM operation. In turn, the flexible use of the runways is anticipated to deliver less airborne and runway holding as well as a significant reduction in the number of late running departures. With regard to this last point, ACL is requested to use all means available to avoid night time operations and where such flights take place to provide a detailed account of the rationale to the Slot Performance Committee.
