rates for each of these  modes and conditions allows the calculation of emissions from each  testing mode.  The methodology for calculating overall emissions from aircraft en gine testing is expressed by  Equation A5-8  ( Total Pollutant Emissions for Aircraft Engine Testing ).  Data inputs required to execute  Equation A5-8  ( Total Pollutant Emissions for Aircraft Engine  Testing ) and their respective sources are listed in the following sections.  Maintenance personnel should be consulted to determine the typical number of test cycles  performed upon each aircraft. In addition, a ircraft engine test time for each testing mode varies  with the engine type, goals of the test, and equipment used.  Therefore, site-specific information  on test times should be obtained from the maintenance personnel performing the testing.  The default average fuel consumption rate, in pounds per minute, of an engine in operational mode, is provided in Chapter 5 of  EPA’s  Procedures for Emission Inventory  Preparation, Volume IV: Mobile Source , 26  and in the ICAO ’s  Engine Exhaust Emissions  Databank 27 . For military aircraft, the EPA’s  Procedures for Emission Inventory Preparation,  Volume IV: Mobile Source  should be used. These engine fuel flow default values are adapted  within EDMS/AEDT.  Emission factors for an aircraft engine are listed by operating mode, generally, in pounds of  pollutant per thousand pounds of fuel consumed. Average emission  factor data for engines by  operating mode are included in EDMS /AEDT and have been adapted from  EPA’s  Procedures  26  EPA,  Procedures for Emission Inventory Preparation, Volume IV: Mobile Sources , Chapter 5, EPA420-R-92- 009, December 1992,  http://www.epa.gov/otaq/models/nonrdmdl/r92009.pdf.  27  ICAO,  Aircraft  Engine  Emissions  Databank ,  http://easa.europa.eu/environment/edb/aircraft-engine- emissions.php.

Total Pollutant Emissions for Aircraft Engine Testing  E = N x TT$_{Mode }$x FF$_{Mode}$/1,000 x EF  Where:  E = total emissions of pollutant.  N = Number of test cycles performed.  TT$_{MODE }$= average test time for a specific testing mode, expressed in minutes.  FF$_{MODE }$= fuel flow rate while in a specific testing mode, expressed in pounds per minute.  EF = emission factor of pollutant (i.e., CO, SO$_{2}$, PM$_{10}$, PM$_{2.5}$, NO$_{x}$, or VOC), expressed in  pounds per thousand pounds of fuel burned.  APPENDIX A5$_{ }$ 30$_{ }$
