A 13-week public consultation has been started by Glasgow airport as it seeks feedback on plans to modernise the airspace used by aircraft.
The airspace change proposals form part of the UK Future Airspace Strategy, an industry-wide initiative driven by the Civil Aviation Authority.
A key element of the strategy involves removing ground-based navigation aids across the UK and using state-of-the-art satellite navigation systems.
The ground-based navigation aid which Glasgow airport uses to guide aircraft will be decommissioned in 2019.
The move to satellite-based navigational systems will help reduce the amount of time aircraft queue, both in the air and on the ground, and reduce overall CO2 and fuel emissions.
The airport is also required to publish an updated noise action plan every five years and will be undertaking a parallel 13-week consultation on a draft scheme.
The noise action plan sets out proposed measures to manage and mitigate the impact of aviation-related noise.
The deadline for submissions for both consultations is April 13.
Operations director Mark Johnston said: “The flight paths used at Glasgow airport have not changed in over 50 years and, as is the case with the wider UK airspace infrastructure, they are simply no longer fit for purpose.
“We now need to ensure the way we manage our airspace matches the advancements that have been made in aircraft technology.”
He added: “Modern aircraft are now equipped to use satellite navigation meaning they can fly more efficient, reliable and direct routes.
“In moving to this new system, not only will we be able to improve the punctuality of flights, we will be able to reduce the amount of fuel burn from aircraft at Glasgow by over 4,000 tonnes.
“To put this in perspective, this is the equivalent amount of fuel an A320-200 aircraft would require to operate 1,370 flights between Glasgow and Frankfurt. This in turn will allow us to reduce CO2 emissions by 21% (12,910 tonnes).
“It is important to stress we will only make changes to the approach or departure flight paths once we have considered the views of all those who respond to the airspace change consultation.
“We will host a number of drop-in sessions over the course of the coming months and all views will then be presented to our regulator, the CAA, before the necessary approval can be granted.
“We are fully committed to growing the airport responsibly and modernising our airspace will help us achieve that. It is important that our communities and stakeholders are fully involved in this modernisation process and we would encourage people to participate.”
