EASA Consults Industry on Special Condition Rules for Electric and Hybrid Propulsion Systems
New Special Condition rules will establish a framework for certifying propulsion systems for eVTOL aircraft

The proposed requirements will cover propulsion systems for manned or unmanned aircraft conducting normal or emergency operations.

The European Union Aviation Safety Agency (EASA) has launched a consultation on a proposed Special Condition rules covering the certification requirements for electric and/or hybrid propulsion systems (EHPS). The proposed new rules, published on January 27, are mainly for propulsion systems developed for new electric vertical takeoff and landing (eVTOL) designs, complimenting the Special Condition VTOL that the agency introduced for these aircraft in July 2019.

Once the Special Condition is established, following a consultation process that ends on March 3, 2020, EASA will propose acceptable means of compliance that can be applied for the certification of specific propulsion systems, taking account of the type of aircraft they are intended to support. In mid-February, the agency is expected to propose acceptable means of compliance for VTOL aircraft.
