Blended Wing Body deep dive: large wing area driven by lift — what JetZero Z4 means for future airliners

Leeham's series examines the Blended Wing Body (BWB) as a potential efficiency step beyond the conventional tube-and-wing. Part 4 shows a BWB's large wing area is driven by lift requirements rather than cruise needs, and assesses what JetZero's Z4 means for design, certification and operations.

Climate change is altering turbulence patterns as cockpits scramble to adapt Climate-driven shifts are increasing the frequency and severity of turbulence, challenging assumptions embedded in aircraft design and cockpit procedures. Avionics, weather sensing and pilot training are struggling to keep pace, forcing operators and regulators to reassess safety margins, routing and equipment requirements.

Eni's Kenyan biofuel project faces farmer backlash — implications for SAF supply and airline reputations Eni has promoted a Kenyan biofuel project as a template for sustainable aviation fuel production, but widespread complaints from smallholder farmers that the scheme "failed them" raise questions over feedstock sourcing, local benefits and reputational risk for airlines seeking SAF credits or offtake agreements.

University of Sheffield demonstrates solar‑driven process for scalable SAF Researchers at the University of Sheffield say a new solar‑driven process can produce sustainable aviation fuel and could be scaled to industrial levels. The approach offers a potentially scalable alternative to waste‑oil feedstocks, reshaping SAF supply pathways and supporting aviation's net‑zero ambitions.
