Frequent Asked Questions

We’ve produced a set of Frequently Asked Questions (FAQs) designed to explain Airspace Change in more detail and how it might affect you and our operations here at Bristol Airport. But if you have any questions that are not answered here, please email [email protected].

What is Airspace?

Airspace is the ‘invisible infrastructure’ in the sky which helps aircraft operate safely.

What is Airspace Change?

Airspace Change is the process through which airspace modernisation will be delivered. It is overseen by the Civil Aviation Authority (CAA) and led by a change sponsor, usually an airport or an air navigation services provider.

Where can I read more information about Airspace Change?

Guidance on the regulatory process for changing airspace design including community engagement requirements can be found in the Civil Aviation Authority’s CAP1616 guidance document here.

Why is Airspace Change necessary?

The airspace in the UK has not been modernised since the 1950s and modernisation is required to improve punctuality of flights, to help reduce CO2 emissions, to help reduce noise and to ensure there is capacity to meet future demand.

What stage are you in the process?

We are at the second step of Stage 1. This involves engaging with local communities and airspace users to help shape the Design Principles to be applied to the airspace change design.

What is a Design Principle?

A design principle encompasses the safety, environmental and operational criteria and the strategic policy objectives that a change sponsor seeks to achieve in developing the airspace change proposal.

How do I get involved in the Airspace Change process?

We will be inviting stakeholders to participate in the development of our Design Principles. At Stage 3 we will be undertaking comprehensive engagement with stakeholders through a formal consultation phase of at least 12 weeks, during this stage anyone is welcome to respond.

What is the timeline for Airspace Change?

The timescale for completion of the full airspace change process depends on the complexity of the airspace design and the potential impacts of the change. These factors will determine the amount of design work and analysis of the impact of different options, the degree of consultation and engagement needed with those affected, and how quickly a solution can be developed that takes their views into account.

Why does the process not include flights over 7000ft?

Flights above 7000ft are high enough so that the impact of overflights is less severe for those on the ground below. It is stipulated in the guidance that consultation with stakeholders on the ground is not required for route changes above 7000ft.

What is the role of the Civil Aviation Authority?

The Civil Aviation Authority is the UK's specialist aviation regulator and created the guidance document that change sponsors need to follow to create an Airspace Change. The guidance document is available here.

The Civil Aviation Authority has responsibility for deciding whether to approve changes proposed to the design of airspace over the UK and checks that the airport has properly followed the process, allowing the proposal to proceed to the next stage.

Will any proposed changes affect Bristol Airport’s hours of operation?

No. There are currently no proposed changes to the hours of operation of the airport.

Is Airspace Change required as part of Bristol Airport’s plans to increase capacity to 12 million passengers a year?

While airspace change is not a requirement for growth to 12 million passengers a year, Bristol Airport is committed to exploring opportunities to improve airspace arrangements.  The airspace change process is lengthy so by starting now we can ensure any potential benefits can be realised as soon as possible.

Where can I find more information about Airspace Change?

More information on Airspace Change can be found on the Civil Aviation Authority’s website.
