Airspace Modernisation Update

Why MPs must protect communities from new aviation noise and support an independent oversight ombudsman.

Headline update

The Department for Transport has published new air navigation guidance and directions to support the Civil Aviation Authority in modernising UK airspace. Government says modernisation should help deliver quicker, quieter, cleaner and more resilient journeys, but communities under and near flight paths remain deeply concerned about how the changes will affect aircraft noise, respite, health and local quality of life.

• The Department for Transport published its airspace modernisation impact assessment, air navigation guidance and air navigation directions on 10 August 2026.
• The Civil Aviation (Consumer Protection and Regulatory Reform) Bill has moved from the House of Lords to the House of Commons, with the Commons first reading listed for 1 September 2026.

What has changed?

• Noise impacts are now prioritised only up to 5,000 feet, rather than the previous 7,000 feet threshold.
• Above 5,000 feet, efficiency and carbon reduction are given greater priority.
• CAGNE is concerned that this could reduce protection for communities that still experience significant aircraft noise between 5,000 and 7,000 feet.
• Ongoing evaluation through CAA monitoring and reporting, and industry engagement – note no community element in the guidance.
• Future flight path changes may concentrate noise over new or previously quieter communities, including rural areas and areas not currently overflown.
• Where airspace efficiency and carbon reduction are prioritised, residents may see reduced protection from aviation noise impacts above the lower threshold.

“Studies have shown the lower the aircraft, the greater the noise. We have already fought to get aircraft up to 7,000ft, and wanting to lower it shows a blatant disregard for those already impacted.

“The government has chosen to put 10,000 households at risk of more noise pollution in a desperate attempt to cut green emissions”, says CAGNE.

Why communities should be concerned

Airspace modernisation may change where aircraft fly, how often communities are overflown, and whether noise is concentrated over particular areas. While government and industry emphasise efficiency and carbon savings, the local impact may be uneven. Some communities could experience new or intensified aircraft noise while others benefit from changes elsewhere.

• At Heathrow (daytime, 51 dB LAeq,16h):
  • 359,700 households are within the 7,000 ft noise contour.
  • 353,500 households are within the 5,000 ft contour (a reduction of about 2%).
• At Gatwick (daytime, 51 dB LAeq,16h):
  • 17,600 households at 7,000 ft; 16,600 at 5,000 ft (a reduction of about 6%).

“Airspace modernisation is being dressed up as green progress, but if it enables more flights, it means more emissions, more noise and more misery for communities on the ground.”

Why an independent ombudsman is needed

• Loss of public trust: Communities may perceive decisions as weighted towards industry and operational efficiency rather than residents lived experience.
• Legal and reputational risk: Weak scrutiny of noise and equity impacts could increase the likelihood of challenge and undermine confidence in the process.
• Data uncertainty: The exact distribution of impacts cannot be known until detailed airspace proposals are developed, making independent review essential at each stage.
• Equity concerns: Some households may bear a disproportionate share of negative impacts while wider economic and operational benefits are claimed nationally.

“For too long, governments have swallowed the aviation industries greenwash while communities on the ground pay the price. Airspace modernisation is being sold as a climate solution, but if it enables more flights, emissions will rise — and so will the misery of aircraft noise for communities already suffering under flight paths and those newly impacted. This is not progress; it is profit dressed up as environmental responsibility.”

What we are asking MPs to do

• Creation of an independent ombudsman or equivalent oversight body for airspace change, separate from the CAA and change sponsors. First reading of the CAA Bill is in the House of Commons is on the 1st September.
• A requirement that community noise, health, respite and fairness impacts are independently assessed before major airspace decisions are approved.
• Clear rights for affected residents and local authorities to challenge inadequate consultation, modelling or mitigation.
• Transparent reporting on who gains and who loses from proposed airspace changes, including communities newly affected by overflight.

Message to share

Airspace modernisation must not come at the expense of communities on the ground. CAGNE is calling on MPs to support independent oversight ombudsman, transparent evidence, meaningful consultation and a clear route of redress for residents affected by aircraft noise.
