During this week's Singapore Airshow, Eve opened up about progress on the development of its four-passenger eVTOL aircraft, reporting that it is ground testing a full-scale proof-of-concept prototype that could be ready to start flying in a few months. Meanwhile, Australian companies Microflight, Aviair, and HeliSpirit signed agreements that could lead to 90 more sales of the all-electric aircraft.

At least 100 of the 500 Vertical Aerospace VX4 eVTOL aircraft that leasing group Avolon ordered in 2021 are to go to Malaysia-based AirAsia, which plans to offer ride-hailing flights booked via its app. Avolon has now placed 450 of the four-passenger aircraft with carriers also including Japan Air Lines and Brazil's Gol and Grupo Comporte. It will work with AirAsia to conduct market research for urban air mobility services and secure all the necessary approvals.

With its Alice all-electric aircraft now expected to make its first flight in the next few weeks, Eviation's co-founder and CEO Omer Bar-Yohay is leaving the business just weeks after former chairman Roei Ganzarski departed. The U.S. company announced that its president, Gregory Davis, is stepping into the CEO's role as it works to keep type certification of the redesigned model on track.

Japan's largest airline, ANA, is set to be involved in Joby's planned eVTOL air taxi services, which could start in the Asian country by 2025. Under a collaborative venture that also involves carmaker Toyota, the partners are laying the groundwork for routes such as a 15-minute flight from the center of Osaka to the populous region's offshore Kansai International Airport.

A $1 billion finance deal with Aviation Capital Group is expected to provide liquidity for Volocopter to produce its eVTOL aircraft family and lease some of the vehicles to other operators. The German company's core business model envisages it having full control of planned commercial air taxi services, with some involvement by operating partners.

Odys has trialed a subscale demonstrator for its patented process for generating vectored thrust via extending the wing flaps to support both vertical and cruise phases of flights. The start-up intends to fly a single-seat scale model of the hybrid-electric eVTOL aircraft before the end of 2022, boosted by a seed funding round that raised $12.4 million and an earlier commitment from public charter operator JSX to buy an initial 200 units.

Amprius says its latest 450-Wh/kg, 1150-Wh/L high-energy-density lithium-ion cells represent a step-change in battery performance that could support a wide variety of new electric aircraft. The company's Si-Nanowire silicon-based anodes are a key differentiator because they have lower resistance than traditional electrodes, resulting in higher power.

AutoFlight has posted a video of its Prosperity I eVTOL aircraft flying. Significantly, the footage shows the all-electric model’s first full transition from vertical to horizontal flight and features a detailed explanation of how its eight rotors and two pusher propellers work. The remotely piloted flight was made at the Chinese company’s flight test area in JiangSu province with CEO Tian Yu and a team of 40 staff involved. The Prosperity I cruised at an altitude of almost 500 feet, reaching speeds of 123 mph. When the production aircraft is ready to start air taxi operations in around 2025, it will carry a pilot and three passengers on trips of up to around 155 miles.

EHang is reportedly close to completing type certification in China for the two-seat, all-electric EH216 eVTOL aircraft. In 2021, the company announced plans for a larger, longer-range model called the VT-30, and both vehicles are intended to be operated autonomously, without a pilot on board.
