Dovetail Electric Aviation says it is confident of agreeing the certification basis for its DovePower electric propulsion system with Europe’s civil aviation regulator by year-end. The developer’s outlook follows its first firm customer agreement and a battery industrialization pact, strengthening its path toward commercializing the powertrain.
Electra says it has completed a series of demonstration flights with its ultra-short takeoff and landing hybrid-electric aircraft, testing a potential feeder role for major airports. The demonstrations assess whether the aircraft’s short-field capability can support new regional connectivity models around existing airport infrastructure.
American Airlines paused a contrail-avoidance trial shortly after launching it, as a spring surge in jet fuel prices prompted the carrier to target costs. The decision highlights the operational and economic tension between aviation’s climate initiatives and immediate fuel-price pressures.

Hybrid-electric aircraft startup Ampaire has secured $19 million in Series B funding from IAG, Alaska Airlines and venture capital investors. The financing brings strategic airline backing alongside private capital as Ampaire advances its hybrid-electric aviation technology and commercialization efforts.
Stralis, a developer of hydrogen-powered aircraft, is shutting down after saying the slow pace of ecosystem development has weakened commercial demand and impaired its ability to raise capital. The closure underscores the financing pressure facing emerging aircraft technologies before supporting infrastructure and markets mature.
A trial covering North Atlantic airspace is underway to evaluate contrails at operational scale. The Aug. 18, 2026 report provides limited detail on the trial’s participants, methods or findings, but marks a move from localized research toward testing across a major oceanic flight corridor.

A UK-led consortium will begin a 30-month trial in Shanwick oceanic airspace later this year, directing hundreds of commercial flights to make minor altitude or route adjustments to avoid climate-warming contrails. The operational evaluation will test whether airspace-scale rerouting can reduce aviation’s climate impact without disrupting traffic flows.
