LAMP 1A is a major airspace change proposal affecting airspace arrangements in south-east England, from Stansted to
the Isle of Wight. The package has been developed over the last three years and was submitted to the CAA in February
It is intended to modernise airspace structure, improve operational efficiency and environmental performance,
minimise delays and deliver safety benefits. It includes five separate airspace change proposals (ACPs) some of which
are inter-related and cannot occur unless other of the airspace changes also take place. The overall fuel and CO2
savings, which are an important factor when considering these ACPs, are only delivered if all the modules are

The purpose of the 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 and decision, and if not to ascertain why and determine the most appropriate course of action.
PIR due date
Details of the PIR submission requirements.
Scope and objectives of the review determined
and our confirmation of the data requirements issued to the organisation that
requested the change.
PIR initiation date
The CAA is aiming to complete the PIR of Modules A, D and B by Christmas 2017 and will publish the results when that work is complete. Thereafter, the CAA will complete the PIR of Modules C and E, after which we will publish the final outcome when that work is complete.
The CAA has completed the PIR of the LAMP 1A airspace change proposal. CAP 1692 summarises the outcomes of the five individual LAMP Phase 1A modules. A further five reports (CAP 1692A to CAP 1692E) cover each of the five Modules A to E.
These reports include links to relevant PIR track data diagrams and supporting data where applicable. These links (shown in Bold Red Font) appear in the reports as a cross reference to the supporting material (e.g. A01) to enable interested parties to relate the
impacts described in the report to the resultant traffic patterns arising from the changes. Links to the files are also set out below under LAMP 1A PIR data provided by the sponsor.
As a result of our analysis, the CAA has concluded that the LAMP 1A PIR does show that the proposal has been implemented and operated as expected.
