This document defines the technical guidelines for the safe integration, operation and maintenance, and for certification of Liquid Hydrogen Storage Systems (LHSS) in aircraft. This document also defines guidelines for safe refuelling operation of hydrogen for aircraft.
This document does not address airport infrastructure, nor how the refuelling means is specified, except the provisions required for the safety of the aircraft refuelling operation.
Rationale: Procurement for Hydrogen systems in aviation is increasing and a standard that deals with the specifics of liquid hydrogen systems and aircraft's ecosystem is necessary and relevant.
