Eurocae calls for participation in WG-105 UAS design and airworthiness performance standards

European standards agency EUROCAE is launching a Call for Participation to inform interested parties about a new activity undertaken by Working Group 105 Unmanned Aircraft Systems (UAS). A guidance document was proposed to be developed in Sub Group 4 Design and Airworthiness with the title ‘Minimum Operational Performance Standards (MOPS) for Command Unit Core Layer of UAS to be operated in the EASA certified category of operations’.

The objective is to elaborate a Remote Pilot Station (RPS) MOPS for the EASA certified category of operations. It will focus on RPS Core Layer, as proposed by ICAO, and refined by EASA in RMT.0230 EASA concept for regulation of Unmanned Aircraft Systems (UAS) operations in the ‘certified’ category and Urban Air Mobility – Issue 3.0, that can be used as Acceptable Means of Compliance (AMC) for certification.

RPS is one of the main novelties of RPAS. The solutions which are available today are very heterogeneous, and the impact of certification is not fully understood and consistently implemented across the industry. This document will provide a standardised approach for Type Certification, leading to more efficient certification processes. In addition, this document could facilitate a future standalone RPS certification approach (e.g., ETSO or similar).

To perform this activity, expertise is required from organisations in the following domains:

  • RPAS and RPS design, architecture, functions, and performances
  • RPAS Type Certification standards
  • General Airworthiness Certification and Safety Assurance processes
  • RPAS Operators

WG-105 is tasked to develop the necessary standards to enable safe integration of UAS, or RPAS when controlled and monitored from a Remote Pilot Station (RPS), into all classes of airspace, with due consideration of the emerging European regulatory proportionate risk-based approach, of the related categories of operations (Open, Specific and Certified) and of the industry requirements. WG-105 is also tasked, in cooperation with the Technical Advisory Committee (TAC), to develop proposals for future activities (to be reflected in the Technical Work Programme (TWP)).

WG-105 is organised in six Sub Groups, each working in a specific area. The work performed by the Sub Groups is coordinated by a Steering Committee, which ensures developmental consistency. The current focus areas are:

  • Detect and Avoid (DAA)
  • Command, Control, and Communication, Spectrum and Security (C3&S)
  • UAS Traffic Management (UTM)
  • Design and Airworthiness (D&AW)
  • Enhanced RPAS Automation (ERA)
  • Specific Operational Risk Assessment (SORA)

Call for participation closes: 25 February 2022
