Tackling airspace inefficiencies is “long overdue” and will happen “under my watch”, a minister has pledged.

Aviation minister Mike Kane said UK airspace management is “an analogue system in a digital age”, and improvements will lead to “quicker, quieter, cleaner flights”.

He was speaking at an easyJet sustainability event at Cranfield University, where the airline said inefficient use of airspace contributes to increases in fuel consumption, carbon emissions and flight times.

The carrier described the problem as a “universal issue” across the whole of Europe, but the “greatest inefficiencies” for its operations are in the UK.

Among the causes are aircraft being required to climb in steps after take-off, complex routing, and delaying descents to manage the workload of air traffic control (ATC) staff.

Mr Kane told the audience he and easyJet chief executive Johan Lundgren have “banged on about this for years” while Labour was in opposition.

He said he wants to develop “a Britain where the negative impacts of aviation are minimised”.

He went on: “We have an analogue system in a digital age, closer to the time that (Soviet cosmonaut) Yuri Gagarin flew into space (in 1961) than today.

“That’s going to change under my watch.

“We can all enjoy quicker, quieter, cleaner flights that are better for our people and better for our planet.

“The highways in the sky were mapped shortly after (Cranfield University’s forerunner) the College of Aeronautics opened in 1946, so it’s safe to say that airspace modernisation is long, long overdue.”

Labour’s general election manifesto included a pledge to “secure the UK aviation industry’s long-term future” including through “encouraging airspace modernisation”.

EasyJet published the results of an AI-based study that found airspace inefficiencies increased its CO2 emissions in the year to the end of July by 10.6%.

For its flights from London Gatwick to Milan Malpensa, Italy the figure was around 19%.

Applying its analysis to the whole of European aviation, it estimated that airspace modernisation could help eliminate 18 million tonnes of CO2 from the continent’s skies every year.

Other inefficient routes highlighted by the carrier are flights to Gatwick from Palma de Mallorca, Spain; Faro, Portugal; and Nice Cote d’Azur, France.

EasyJet is calling on the UK Government to complete an airspace modernisation programme focusing on the South East.
