New Publication: ED-334 "Guidance for Common mode analysis for lift - thrust system for VTOL enhanced category"

We are pleased to announce the publication of ED-334 "Guidance for Common mode analysis for lift - thrust system for VTOL enhanced category".

ED-334 contains the results of discussions and considerations regarding Common Mode Analysis (CMA) application for Lift Thrust System for eVTOL (electric vetical take-off landing aicraft). The objective is to give guidance for the application of Special Condition for VTOL and proposed Means of Compliance Special Condition for VTOL considering the enhanced category. The Special Condition VTOL and Means Of Compliance 4 Special Condition VTOL respectively require the no single failure criteria paying particular attention to common cause failures, including common mode errors and cascading failures in Means Of Compliance VTOL.2510.7b when independence cannot be shown. In addition, Means Of Compliance 4 VTOL.2300 gives a special focus on Fly by Wire, highlighting the need for high integrity and availability.

A big thank you to the dedicated members of WG-112 for their invaluable contributions!
