Air Race E announces new electric race classes
Air Race E, the world's first all-electric aircraft race, has announced the introduction of two brand new race classes.
The Performance Class (a standard electric powertrain aircraft produced by a single manufacturer), and V Class, (V-TOL Vertical Take Off and Landing), categories will be raced separately to the existing Open Class as part of the Air Race E series set to stage its first international event in 2022.
Please find attached concept images to depict what each new class may look like, and a press release with more information.
| Air Race E Expands with New Electric Race Classes
Following the success of its first race class, Air Race E, the electric air race, has announced it is launching two new distinct race classes: one an airplane and the other a VTOL (Vertical Take Off and Landing aircraft). The move to amplify its operations and create more races is the direct result of high levels of interest and demand from across the industry.
The new airplane formula will be named the Performance Class and will be based on a standard electric powertrain, which will focus on optimisation, efficiency and extracting the maximum potential out of a powertrain. Air Race E is developing this new race plane under its own roof with the help of leading manufacturers in the industry.
Some modifications and enhancements will be allowed in the Performance Class to continue Air Race E's mission of accelerating technological innovation and showcasing new technologies in the aerospace electrification industry.
Air Race E's existing race airplane formula will be re-named the Open Class referring to the fact that any and all manufacturers can produce their own unique powertrain configurations up to 150kW power. Both airplane classes will be raced according to the same rules but with differences governing the powertrains.
The new electric VTOL class will be named the V-Class. VTOLs – often called flying cars – are a different category of aircraft altogether and at the forefront of electric technology in aerospace. Air Race E is positioning this class as "The World's First Vertical Motorsport." The race format and rules will be somewhat different than the other two race classes and will be revealed soon.
Jeff Zaltman, CEO of Air Race E, said: "The launch of the new Performance Class and V-Class will allow us to include more stakeholders in our project and greatly increase our ability to meet the needs of the industry while organising a thrilling motorsport.
"The Performance Class will provide deeper insights on power management and best practices and will steer more dedication to the sub-systems such as cooling, battery management systems, power electronics and aerodynamics.
"The V-Class demonstrates a major step-change in air racing. Air Race E will be working directly with the top pioneering organisations in the e-VTOL world to shape the event to be at the vanguard of both technology and entertainment in this next generation of motorsport."
Air Race E is partnering with industry leaders such as Airbus, which is the Official Founding Partner, and Ansys, which is the Official Simulation Software Partner, among other top industry pioneers, as it works to develop the innovative technologies needed to make these new race classes come to fruition.

About Air Race E Air Race E is the world's first all-electric aircraft race and will launch as the world championship air race in its inaugural series of international races in 2022. Run by Air Race Events and led by world-leading air racing promoter Jeff Zaltman, the man behind the globally successful Air Race 1 World Cup championship series, the race is set to revolutionize air racing and pioneer innovations in electric aviation. Air Race E will see electric airplanes race directly against each other on a tight 5km circuit just 10m above the ground and at speeds faster than any land-based motorsport. The demand for speed, performance and power management under the rigors of a competitive race environment provide the perfect platform for the development and promotion of cleaner, faster and more technologically advanced electric engines. The events are sanctioned by the Formula Air Racing Association (FARA), the international governing body for formula air racing.

FAA Statement on Pratt & Whitney Engine Emergency Airworthiness Directive
The FAA issued an Emergency Airworthiness Directive (AD) tonight that requires U.S. operators of airplanes equipped with certain Pratt & Whitney PW4000 engines to inspect these engines before further flight.
The FAA is taking this action as the result of a fan-blade failure that occurred Saturday on a Boeing 777-200 that had just departed from Denver International Airport. Although the aircraft landed safely, the failure resulted in damage to the engine, an in-flight engine fire, and damage to the airplane.
After reviewing the available data and considering other safety factors, the FAA determined that operators must conduct a thermal acoustic image (TAI) inspection of the large titanium fan blades located at the front of each engine. TAI technology can detect cracks on the interior surfaces of the hollow fan blades, or in areas that cannot be seen during a visual inspection.
As these required inspections proceed, the FAA will review the results on a rolling basis. Based on the initial results as we receive them, as well as other data gained from the ongoing investigation, the FAA may revise this directive to set a new interval for this inspection or subsequent ones.
The previous inspection interval for this engine was 6,500 flight cycles. A flight cycle is defined as one takeoff and landing.
This AD is effective immediately upon receipt. The FAA will share this information with other international civil aviation authorities.
FAA Announces Application Period for LAANC [unmanned air systems]
The FAA announced the application period for entities to become FAA Approved UAS Service Suppliers of the Low Altitude Authorization and Notification Capability (LAANC). The application period opens on May 3, 2021.
LAANC is a collaboration between the FAA and the drone industry that directly supports the safe integration of drones into the nations airspace. Launched in 2017, the capability covers 80 percent of controlled National Airspace at 400 feet or below and expedites the time it takes for drone pilots to receive near real-time authorizations to fly in this space. All drone pilots operating in LAANC-enabled areas under the FAAs small drone rule or under the exception for limited recreational operations can access the capability through FAA Approved LAANC Service Suppliers.
LAANC provides drone pilots with industry developed applications to obtain near real-time airspace authorizations for operations in a controlled airspace below 400 feet. LAANC does not provide entities with the authority to regulate the airspace or grant access without FAA approval.
The Schedule is:
- Application Period: May 3 June 4, 2021
- FAA Submission Review: June 7 July 9, 2021
- Technical Interviews: June 12 August 13, 2021
- Formal Onboarding: August 16 October 15, 2021
The FAA is announcing the application date more than two months in advance to help applicants prepare, as they must have a mature product at time of application. Information on requirements and the onboarding process can be found on FAA.gov.
