Post Implementation Review

The purpose of the Post Implementation Review (PIR) is for the CAA, as the independent regulator, to assess whether the change has delivered the anticipated impacts and benefits set out in the original Airspace Change Proposal (ACP) and decision, and if not to ascertain why and determine the most appropriate course of action.

Publication of our report

The CAA has completed the PIR of the Heathrow WOBUN / BUZAD SID Truncation airspace change proposal. Truncation of London Heathrow WOBUN and BUZAD SIDs (ACP-2017-73) – Post Implementation Review (CAP2133) describes the outcome of the PIR.

As a result of our analysis, the CAA has concluded that the Heathrow WOBUN / BUZAD SID Truncation PIR does show that, following the implementation of additional mitigation actions, the proposal has been implemented and operated as expected.
