Airspace Change 2020 Implementation – Post Implementation Review (ACP PIR)

Farnborough Airport conducted a 12 month data capture process between April 2022 and March 2023, in line with the CAA’s pre-requested data requirements. The results were sent to the CAA in April 2023 and uploaded to the CAA portal as a Post Implementation Report which is required by CAP 1616.

This web page on the CAA website holds all the relevant historic documentation and occasional updates from the CAA.

For more information regarding ACP PIR please see Farnborough Airport website’s Airport Matters page.

The PIR is not a review of the decision that was made on the airspace change proposal, and neither is it a re-run of the decision making process. The following outcomes may result from the post implementation review:

• the CAA may confirm that the implemented design satisfactorily achieves – within acceptable tolerance limits – the objective and terms of the CAA’s approval, and the airspace change is confirmed; or
• the CAA may require modifications to better achieve the objective and terms of the CAA’s approval; once the modifications have been implemented and operated for a period (approximately six months), there are three further possible outcomes:
  • noting that the modifications did not better achieve the objective and terms of the CAA’s approval, the CAA may conclude that the original design was satisfactory and the original airspace change is confirmed; or
  • noting that the modifications did not better achieve the objective and terms of the CAA’s approval, the CAA may conclude that the original design was not satisfactory and the original airspace change is not confirmed. In this case, in order to pursue its airspace change, the change sponsor will need to commence a fresh airspace change proposal from Stage 1; or
  • the CAA may conclude that the modifications do better – within acceptable tolerance limits – achieve the objective and terms of the CAA’s approval and so the modified design will be confirmed
  • the CAA may determine that the implemented design does not satisfactorily achieve the objective and terms of the CAA’s approval, and modifications are not practicable. In any such case, the change sponsor may be required to revert to the previous airspace design
