The UK Civil Aviation Authority and the European Aviation Safety Agency have reached an agreement to jointly certify the aircraft of Vertical Aerospace, providing the company with more control over certification tasks. In Sweden, the start-up Heart is making changes to the propulsion system of their planned hybrid regional airliner to enhance its design. Meanwhile, Cranfield has secured additional funding to develop a hydrogen-powered airliner demonstrator based on a nine-passenger converted Islander aircraft, with plans to introduce it to the market by 2027. On a global scale, business aircraft flying saw a decrease in North America and Europe during June, while other parts of the world experienced an increase in activity. This suggests varying levels of engagement in the business aviation sector worldwide.
