An account is presented of the analytical procedures and data processing techniques employed in translating field-measurement data of aircraft exhaust emissions into a form consistent with the needs for the promulgation of realistic standards. Pollutant mass emissions for carbon monoxide (CO) hydrocarbons (HC) and the oxides of nitrogen (NO(x)) are computed for an aircraft operational cycle comprised of the following modes: taxi/idle, take-off, climb out and approach. The calculations are for specific engine power (or thrust) settings for each mode as well as for specified times in mode. Numerical results are tabulated for each individual engine tested together with summaries obtained by aggregating engine data on a model basis. Data are presented for turboprop/turbine engines, light-utility piston engines and auxiliary power units. (Author)
