Drivers for airspace change
• Airspace Modernisation is an EU and UK Government policy objective
An airspace change is required The introduction of new routes The main initiatives that to enable the removal of based on satellite navigation is industry stakeholders conventional ground-based a key part of the Government’s including airports must navigation aids and support the Aviation Strategy that sets out deliver to achieve the widespread introduction of new the UK’s overall ambition to objectives of the routes based on satellite deliver quicker, quieter and Aviation strategy are set navigation..* cleaner journeys.. out in a separate Airspace Modernisation Furthermore, EU regulation Strategy (AMS). 2018/1048 mandates that the City of Derry airport must have satellite-based approaches by January 2024.

CAP1616
• The Civil Aviation Authority's (CAA) guidance on the regulatory process for changing airspace design is detailed in CAP1616.
• CAP1616 provides a process framework to be used when designing airspace and it is split into 7 Stages.
• CAP1616 sets out the process for developing airspace change options. This involves engaging with affected stakeholders, evaluating the impacts of options, consulting the public, regulatory approval and implementation. Classification: Public
CAP1616 – the 7 Stage Process
1. Develop design principles with our stakeholders
2. Create multiple options to best meet those principles and assess each option
3. Perform a detailed assessment on the preferred option(s) and formally consult with our stakeholders on the preferred option.
Collate the consultation feedback and produce a report
4. If applicable, update the design based on consultation responses and submit the proposal for the change to the CAA
5. CAA assess the application and issue a decision
6. Implement the change 7. Post-implementation review by the CAA Classification: Public What is Performance Based Navigation (PBN)?
• Today pilots normally navigate by flying from point to point using fixed, ground based navigation aids.
The flight paths are constrained by the position of the ground-based navigation aids.
• In the future aircraft will navigate using satellite technology using new virtual geographical waypoints int the sky.
Flight paths are no longer constrained by the position of the ground- based navigation aids. Classification: Public

Arrival flight path Classification: Public
Summary of proposed changes
• The City of Derry Airport is proposing the following: To introduce PBN approaches to each runway end To introduce PBN direct arrival procedures to compliment the above. To introduce PBN Missed Approach Procedures, Aircraft Holds and holding procedures.
• As much as possible, the aim is to design PBN approaches and arrival procedures to replicate the existing routes – which would result in little noticeable change to stakeholders.
• As much as possible, the vertical and lateral profiles of the aircraft will remain the same.
• The full Statement of Need outlining the proposal is available on the CAA Portal here at Step 1a. Classification: Public
Stage 1
Design Principles Classification: Public
What is a Design Principle?
• CAP1616 guidance requires the production of design principles for each airspace change.
• Design principles essentially provide a list of high-level criteria that the proposed airspace design options should meet. They also provide a means of analysing the impact of different design options and a framework for choosing between options.
• CAP1616 states that principles: ”are in no way immutable, and, as a part of the process for the establishment of the airspace design principles, should be challenged as part of the ongoing dialogue with stakeholders”. Classification: Public
Prioritisation of design principles
• CAP1616 highlights that design principles can be contradictory, for example, where avoiding one kind of impact is likely to increase another: “some of the principles may contradict one another and some may be prioritised over others: this will be an iterative process and a qualitative one rather than a purely numerical exercise with binary answers”.
• Prioritisation of the design principles help our airspace designers to compare different design options, when we reach that stage of the CAP1616 process. Classification: Public
Our proposed design principles
1. The proposal must maintain a high level of safety. 2. The proposal should avoid overflight of densely populated areas where possible*. 3. The proposal must be in accordance with the Airspace Modernisation Strategy (CAP1711) and any current or future plans associated with it.** 4. The proposal should replicate the current tracks over the ground as much as possible, to avoid placing new flightpaths over areas not currently overflown. 5. Minimise impact on other airspace users and limit any requirement for additional Controlled Airspace (CAS). 6. Improve operational efficiency and resilience.
*This is in line with the governments policy to limit **This design principle is mandated by the CAA and, where possible, reduce the number of people in the UK adversely affected by aircraft noise and the impacts on health and quality of life associated with it. Classification: Public
Feedback and Questions
• Prior to COVID-19 we would engage with you via face-to-face workshops, unfortunately due to the current situation we are unable to do this. We have included a FAQ sheet, that may help answer any further questions you may have, but please do email us with any question that springs to mind.
• We would like you to consider this presentation and our proposed design principles and we welcome your thoughts and feedback on them.
• We would like you to consider: Do you agree with our proposed design principles? Do you agree with the order of our proposed design principles? Should any principles be removed? Do you have a design principle(s) you would like us to consider adding?
• If you have any questions, please get in touch via email and return your design principle feedback form by Friday 23rd October 2020.
• Please send any questions & your feedback form to [email protected] Classification: Public
Next Steps
• Design Principle feedback form deadline Friday 23rd October 2020.
• We will produce a summary of all the feedback we received and distribute it to you, along with our final set of proposed design principles.
• We will produce our full Stage 1 submission for the CAA, which will include all your feedback.
• The CAA Stage 1 Gateway meeting will be held on 27th November 2020.
• The proposal will then move onto Stage 2 (Develop & Assess) of the CAP1616 process. Classification: Public
