ISO 6966-2:2005 specifies the minimum design requirements applicable to all aircraft ground support equipment in order to ensure * safety of staff operating or maintaining the equipment or in its vicinity; * protection of aircraft against interference or damage. The requirements of ISO 6966-2:2005 apply to any piece of aircraft ground support equipment used on airports. ISO 6966-2:2005 does not provide all the design requirements applicable for aircraft ground support equipment. Other requirements apply, and can be found in separate standards: * ISO 6966-1 specifies the general, other than safety related, design requirements applicable to all aircraft ground support equipment; * ISO 4116 specifies the additional requirements applicable for conveying surfaces of those pieces of aircraft ground support equipment intended for handling and loading of baggage and cargo unit load devices; * specific standards, listed in the Bibliography, define the functional and performance requirements for certain types of aircraft ground support equipment.
