EASA Special Condition for VTOL

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. This
special condition addresses the unique characteristics of these products and prescribes airworthiness
standards for the issuance of the type certificate, and changes to this type certificate, for a personcarrying VTOL aircraft in the small category, with lift/thrust units used to generate powered lift and
control.
