EASA has issued a special-information paper dealing with the validation of new generation flight simulation training devices (FSTD)—including virtual reality (VR) and augmented reality (AR)—that eventually paves the way for approval and use of these devices, particularly with regard to eVTOL pilot training.
The agency notes that “existing certification specifications (so-called Primary Reference Documents (PRD)) to evaluate and qualify FSTDs for pilot training—CS-FSTD(A) issue 2 and CS-FSTD(H) Initial issue—cannot serve or not entirely serve as a qualification basis. Following a gap analysis, they have to be amended or modified by special conditions (SCs). The definition and use of SCs is a faster way to amend the existing certification specifications than an update by a standard rulemaking process.” This includes FSTD special conditions for using head-mounted displays (HMD) combined with a reduced envelope motion platform.
