Passenger stairs
1 Scope
This standard specifies the technical requirements, test methods, inspection rules, labelling, marking and instructions for use, and packaging, transportation and storage of passenger stairs.
This standard is applicable to all passenger stairs for passengers to get on and off aircrafts in the field of civil aviation.
Note: The passenger stairs in this standard refer to the special equipment for passengers to get on and off the aircraft on the apron, which are usually classified into internal-combustion passenger stairs, electric passenger stairs and hand-push passenger stairs.
