All applicants will be notified about the funding decision via email prior to the public announcement.

Successful applicants

December 2021 call:

Electronic Conspicuity Interoperability Test Programme ECITP sponsored by The Aviation Innovation Centre at Goodwood Aerodrome



The objective is to provide a rapid test facility with the expertise, systems and operational capability to gather accurate data about the interoperability of airborne and ground-based EC solutions and the performance of the associated airspace integration concepts that they are intended to enable.

Light GA Digitisation of Flight Data sponsored by Skyverse



This proposed ‘Digital Intentions’ project was a proof of concept to show end-to-end digital transfer of VFR flight details via the internet in order to cut out mundane RT, reduce ATCO workload and provide richer information to all ANSPs. The final report and trial video can be found on the Skyverse website.

March 2022 call:

FID Template Documentation for AFIS Airfields sponsored by Custom Chess Company



The project will create a set of product agnostic FID template documentation providing suitable guidance and Acceptable Means of Compliance to reduce the burden on AFIS units, whilst also providing some common standards to the documentation that will improve the efficiency of the CAA’s approval process and encourage common standards across industry.

Trial of ADS-B Obstruction Beacons on 978Mhz UAT sponsored by uAvionix



The purpose of the trial was to evaluate the efficacy of the obstruction beacons from the point of view of the operator and of other airspace users. This was be achieved by gathering feedback both verbally, by email and via questionnaires. This project completed in April. You can view the final report here

Reduced Departure Divergence Industry Research for Updated Minimum Standards sponsored by Heathrow & Gatwick Airports



The objective of the research project is to reduce the existing minimum standard angle of divergence for conventional departures below 45˚, validated using flight data from existing Standard Instrument Departure (SID) routes and a robust analytical approach to loss of separation risk modelling.

Masterplan cumulative impact assessment and trade-off analysis sponsored by Glasgow and Edinburgh airports



This project focuses on how one airspace change affects another. This is tackling cumulative impacts and trade-offs using robust and practical approaches. This can be shared with other potential airspace changes to speedup delivery, minimise duplications of effort and divergent methods and reduce chance of failure in the process.

Fair and equitable distribution of aircraft noise - community research sponsored by Gatwick Airport



By working with communities affected by aircraft noise, this work aims to gain information to feed into future airspace changes that will allow the environmental impacts of aviation to be more fairly distributed. The project aims to define a set of metrics of the impact to give it a value that can then be used when a new airspace change application is being progressed so that environmental impacts are reduced overall.

March 2023 call:

Digital Transformation of Airspace Management sponsored by Airspace Unlimited Scotland



This proposal will result in advanced airspace analytics and design prototypes being developed into validated technology. The project outputs will give a systems level viewpoint, expandable to granular detail, on how to improve the design and management of reserved/special use airspace (SUA) and increase environmental performance for all types of user, particularly airlines and the military.

Electronic Conspicuity Interoperability Test Programme 2 sponsored by The Aviation Innovation Centre at Goodwood Aerodrome



This project follows on from phase 1 that completed in August 2023. The project will include further evolution of the Flight Information Display to present the dynamically activated Temporary Reserve Area (TRA) and enable automatic QNH (pressure) updates. It will also test the capabilities required to conduct remotely piloted aircraft systems (RPAS) operations in an atypical air environment.
