Rotorcraft and eVTOL autonomy: FAA/EASA powered-lift and SC-VTOL AI-relevant guidance

Powered-lift and VTOL type-certification pages exist. AI-specific sentences sit on a different FAA page. This article keeps those documents separate.

Status as of 14 October 2026: live fetches of the FAA Roadmap and Safety Framework for Aircraft Automation HTML slugs now return the Version I Roadmap PDF and the Safety Framework PDF (HTTP 200; some earlier passes recorded 403). EASA’s VTOL page still says that in the absence of certification specifications a special condition for VTOL aircraft has been developed. We still found no AI or ML words in AC 21.17-4 or SC-VTOL-02 on the last editorial search of those PDFs.

FAA powered-lift is a special class, not a 21.16 special condition

AC 21.17-4, Type Certification—Powered-lift describes type certification of powered-lift as a special class of aircraft under 14 CFR 21.17(b). The circular states that Special conditions under § 21.16 are not used as part of the certification basis for special classes of aircraft.

We searched the AC 21.17-4 text for “artificial intelligence”, “machine learning”, and a standalone “AI ” token and found none. The circular is powered-lift type-certification guidance. It is not an AI means of compliance.

Where the FAA does name eVTOL, ML and AI together

The Safety Framework for Aircraft Automation (September 2025) says the industry trend to automate tasks is expected to accelerate with new sensor and processing technologies, including machine learning. It names large scale Powered Lift electric vertical take-off and landing (eVTOL) operations as predicated on the successful implementation of automation.

The same framework says to Avoid personification of the automated system(s): Automation is a tool, not a person. It states that this principle is outlined in the FAA Roadmap for Artificial Intelligence (AI) Safety Assurance, as AI-based systems are a form of automation. The Roadmap for Artificial Intelligence Safety Assurance, Version I is that cited roadmap. See Does the FAA certify AI today? and the FAA roadmap explainer.

The Safety Framework is offered to the aviation community as an initial step. It is not an advisory circular and does not publish a powered-lift AI checklist.

EASA SC-VTOL is a VTOL special condition

EASA’s VTOL page says the Agency has received a number of requests for the type certification of vertical take-off and landing (VTOL) aircraft, which differ from conventional rotorcraft or fixed-wing aircraft. In the absence of certification specifications for the type certification of this type of product, a complete set of dedicated technical specifications in the form of a special condition for VTOL aircraft has been developed. The consultation page and SC-VTOL-02 are those specifications. SC-VTOL-02 is titled Special Condition for small-category VTOL-capable aircraft, Issue 2 (June 2024). Issue 2 sets the maximum certified take-off mass (MCTOM) at 5 700 kg, leaving the maximum passenger seating configuration (MPSC) of 9 unchanged.

We searched the SC-VTOL-02 text for “artificial intelligence”, “machine learning”, “AI ” and “autonom” and found none. We do not call SC-VTOL an AI standard.

FAA special class versus EASA special condition

Analysis, not sourced as a regulator comparison: the FAA instrument we cite for powered-lift is 14 CFR 21.17(b) special class, and that AC says § 21.16 special conditions are not used for that basis. EASA’s instrument we cite is a special condition for VTOL written in the absence of certification specifications. Those are different legal tools. Neither page we cite is an airborne-ML acceptable means of compliance.

Questions

Does AC 21.17-4 certify AI in powered-lift?

No sentence we found in AC 21.17-4 names artificial intelligence or machine learning.

Does EASA SC-VTOL-02 set AI or ML objectives?

A search of SC-VTOL-02 found none of those words. The VTOL page describes airworthiness specifications for VTOL products.

Where does the FAA connect eVTOL to machine learning?

The Safety Framework for Aircraft Automation names Powered Lift eVTOL operations and machine learning on the same page, and treats AI-based systems as a form of automation by pointing at the FAA AI Safety Assurance Roadmap.
