VFS is again co-sponsoring the annual Electric Aircraft Symposium (EAS), organized by the Comparative Aircraft Flight Efficiency (CAFE) Foundation, on July 20-22, 2021. This year's 15th Annual EAS will be held virtually! 

The CAFE Foundation and Vertical Flight Society have been working to advance electric aviation for many years and have partnered again for this year’s EAS. Electric and hybrid electric powered aircraft have the potential to significantly reduce air transportation costs, carbon emissions and community noise.

  • Day 3: Technical Session – $80 ($40 for students)

Register for both Day 2 and 3, and pay only $140 — $20 off! (except students)

In 2007, CAFE Foundation hosted the first electric aircraft symposium in North America. In 2011, the Foundation managed NASA’s Green Flight Challenge, which was funded by Google. This US$1.35 million prize was awarded to Pipistrel USA for its winning 4-seat, electric-powered aircraft, the Taurus G4, which flew nearly 200 miles (322 km) non-stop, while achieving 403.5 passenger-MPG (171.5 passenger-km/l)! Its astounding efficiency was more than twice that of the piston-powered aircraft in the competition. 

The Vertical Flight Society was founded in 1943 by the pioneers of the US helicopter industry to advocate for vertical flight and create a robust international technical community. VFS hosted the world’s first electric VTOL technical meeting in 2014, launched the world’s first eVTOL eNewsletter in 2016 and eVTOL website in 2017, and the world’s first eVTOL short course in 2018. The Society also supported the development of the Uber Elevate White Paper and is a Partner of the GoFly Prize competition. VFS now includes profiles on more than 480 electric VTOL aircraft in its World eVTOL Aircraft Directory, www.eVTOL.news

Regional Air Mobility Business Case
The lower energy and maintenance costs of electric-powered aircraft make them well suited for inter-city Commuter/Regional Air Services. This includes new inter-city services and the revitalization short haul routes abandoned because of rising operating costs. Depending on the stage length and available infrastructure, the routes can be served by high speed eVTOL aircraft (with wings), new clean sheet eSTOL and eCTOL designs and older aircraft retrofitted with battery-electric and hybrid-electric propulsion systems by way of an STC.

UAM Business Case
Urban Air Mobility uses three-dimensional transportation to better serve the needs of our communities. UAM or Advanced Air Mobility encompasses intracity passenger, cargo and emergency services operated by electric-powered piloted, remotely piloted or autonomous eVTOL aircraft. The idea of providing urban air service is not new but electric propulsion makes air connectivity more economical and environmentally sustainable.

Aircraft Conversions and Supplemental Type Certifications
Several projects are in place to convert existing aircraft into battery-electric, hybrid-electric and fuel cell electric propulsion. These don't require the Type Certification (TC) of an entirely new aircraft. Engineering the conversions needs to be done carefully to obtain a Supplemental Type Certificate (STC).

Coastal Community Use Cases
A number of factors are accelerating the electrification of aviation in coastal communities. For example, Scandinavian governments have set targets for the introduction of electric-aircraft for commuter and pilot training flights. And environmentally minded communities may be among the first to introduce electric seaplane service and eVTOL aircraft on short haul overwater routes.

Community Integration
As communities and industry come together to implement AAM, it is clear that planning is at the core of a successful approach. Planning for AAM includes everything from vertiport designs and locations, to route planning, to integration into a multimodal transportation system, to addressing issues of sustainability, and more. This planning is an exercise that must happen at the local level, but with the active participation of all stakeholders including industry, regulators, operators, agencies, essential services and the public. This panel will discuss how these stakeholders can come together to address infrastructure policy concerns and develop a broadly supported implementation plan
