54 Man/System Technology and Life Support

Includes human factors engineering, bionics, man-machine systems, life support, space suits and protective clothing. For related information see also 16 Space Transportation; and 52 Aerospace Medicine.


Man-Machine System – A system in which the functions of the man and the machine are interrelated and necessary for the operation of the system. AGARD Multilingual Aeronautical Dictionary, 1980.

Life Support System – That complex of equipment which provides for the maintained health, comfort, and security of a vehicle occupant. Usage excludes atmospheric control (environmental control) but includes provision of food and water, waste collection and disposal, escape and survival gear. AGARD Multilingual Aeronautical Dictionary, 1980.

NASA Interest

Exhaustive Interest : Equipment and systems specifically concerned with the human aspects of aeronautical and space flight.

Selective Interest : Equipment, systems, and life support from non-aerospace activities (other transportation systems, oceanography, mining, industry, and the like) that may have an application in the human aspects of aeronautical and space flight.

Negative Interest : Industrial- and transportation-related equipment, systems, etc. with no aerospace applications.
