Airline representation on the Decision Board

The ASF is funded through the UK State En-route unit rate for commercial air transport and has been agreed for the period 01 January 2020 to 31 December 2024. Any funds not invested or allocated to specific projects will be returned to airlines through an adjustment to the unit rate in the following reference period.

This may need to be adjusted in light of a move away from the five-year reference period to December 2024 to align with a new reference period covering 2023 to 2027 (NR23).

AMS review and its impact on proposal assessment

The CAA has refreshed the AMS in January 2023, to reflect impacts of the COVID-19 pandemic on the aviation industry, outcomes of the UK-EU Transition and to capture requirements of emerging new stakeholders. Rationalisation of the current initiatives, in terms of their form and format took place; however no changes were made that could undermine modernisation activity already underway.

Recovery of VAT

The CAA has decided to award a grant for Airspace Modernisation Strategy (AMS). This grant is administrated by the CAA in form of The AMS Support Fund. The grant shall take the form of reimbursement of eligible direct costs incurred. For more detail on the definition of ‘eligible costs’ please see the section below.

Request for release of funds should include VAT costs where applicable, but the CAA will only grant costs exclusive of VAT. We grant costs exclusive of VAT but the application form will ask for three numbers:

  • Net cost (VAT exclusive cost)
  • VAT amount
  • Gross cost (VAT inclusive)

A copy of a supporting invoice from a third party showing these three elements is required. Once all of the above is provided we will grant only the net element but we will have a complete view of the costs for transparency and any potential future audit purposes.

Definition of 'eligible costs'

Eligible direct costs are costs actually incurred by the grant applicant which meet the following criteria:

  • they are incurred in the period of the grant distribution,
  • they are incurred in connection with the AMS Support fund project
  • they are identifiable and verifiable, in particular being recorded in the accounting records of the beneficiary and determined according to the applicable accounting standards in the UK
  • they comply with the requirements of applicable tax and National Insurance Contributions legislation in the UK
  • they are reasonable, justified and comply with the principle of sound management in particular regarding economy and efficiency.  

Eligible direct costs are those specific direct costs which are directly linked to the implementation of the AMS projects and can therefore be attributed directly to it. In particular the following costs are considered eligible direct costs:

  • the costs of personnel working under an employment contract with the applicant, comprising actual salaries plus National Insurance contributions costs provided that these costs are in line with the beneficiaries usual policy on remuneration;
  • costs of travel and related subsistence provided these costs are in line with the grant applicants usual travel policy
  • cost of consumables, equipment and supplies directly assigned to the AMS project
  • costs entailed by service contracts, including services purchased in connection with the AMS project as well as cost of securing third party advice and support to deliver the AMS project*

Indirect Costs are those which are not specific to the task to be delivered and are therefore not directly attributable to the task. Indirect costs shall not be eligible.

Claims for reimbursement of Eligible direct costs under the AMS grant will be submitted to the CAA through a Request for Release of Funds letter, a copy of which is on the AMS Support Fund website.

*The third party costs incurred in delivery of the work described in the AMS project Request for Release of Funds letter can include subcontracted third party costs only if supported by a subcontractor’s VAT invoice as raised to the grant applicant for payment. Such third party invoices must be attached to the grant claim letter as proof of third party costs actually being incurred. The grant distribution will only reimburse the net amount of third party invoices, the VAT element of third party invoices is considered not eligible for reimbursement under the AMS grant.
