contrails

Business jets can create long-lasting contrails, but their altitude capability offers a solution.

Airlines are looking at how data can help them mitigate contrails as a key way to reduce their environmental impact.

More research is needed to understand the climate impacts of aviation’s non-CO2 emissions ahead of the formulation of policy incorporating them into the ETS.

With the prospect of a favorable cost-benefit ratio, carriers start their own contrail prevention trials.

GE Aerospace unit Aerospace Carbon Solutions has acquired Satavia, a UK-based company specializing in preventing the formation of contrails.

French carrier Amelia has analyzed a dozen flight plans and modified some of them to prevent the formation of contrails as part of a broader Thales-led project.

Power-dense motors; controls from high flyers; rechargeable thermal battery; in-space refueling port.

Modern commercial aircraft flying at high altitudes create longer-lived contrails than older aircraft, according to new research.

Cryo-compressed hydrogen; Nullforming antenna; Contrail mitigation; Condensed battery flies.

Airbus is conducting a flight-test campaign to study the water vapor exhaust from a hydrogen fuel cell system to understand if it will create a contrail.

Breakthrough Energy, a consortium of aviation stakeholders including seven airlines, is seeking EU funding for a large-scale contrail mitigation trial.

The system is intended to enable dispatchers, controllers and pilots to see which areas and contrail formation altitudes to avoid.

In Europe, the monitoring of non-CO2 emissions and their role in aviation’s environmental impact is a hot topic—and airlines are not all on the same page.

IATA Director General Willie Walsh's comments come as the EU prepares for the start of mandatory non-CO2 reporting on Jan. 1, 2025.

Satavia is about to submit a scientific paper for peer review, about its approach and methods.

Organizations are making progress but still debating the best way to prevent contrail formation.

At stake is avoiding large quantities of CO2 emissions, as cirrus cloud-forming contrails total an estimated one-third of aviation’s harmful climate impact.

Fuel systems for hydrogen; 3D printing on the Moon; LH2 tank breakthrough; the cost of avoiding contrails; and Velis Electro approved for training.

While avoiding the formation of contrails is an emerging priority for aviation in reducing its climate impact, cost has been a concern for operators.

Avoiding contrails remains up for debate. Some are already selling tools to carriers. Others argue more work is needed to mature solutions and standards.

Contrail avoidance gains traction, but questions remain.

The agency and airframer are overcoming atmospheric and technical challenges to see how sustainable aviation fuel affects emissions and contrails.

Encouraged by the results of earlier experiments, Eurocontrol is planning further studies and tests on how to prevent contrail formation.

Carbon cycle benefits of SAF are known, but will it help reduce the formation of persistent contrails? A Boeing and NASA flight test looks to find out.
