    Administrator means the Administrator of the Federal Aviation 

Administration or any person to whom he has delegated his authority in 

the matter concerned.

    Administrator of the EPA means the Administrator of the 

Environmental Protection Agency and any other officer or employee of the 

Environmental Protection Agency to whom the authority involved may be 

delegated.

    Aircraft as used in this part means any airplane as defined in 14 

CFR part 1 for which a U.S. standard airworthiness certificate or 

equivalent foreign airworthiness certificate is issued.

    Aircraft engine means a propulsion engine which is installed in, or 

which is manufactured for installation in, an aircraft.

    Aircraft gas turbine engine means a turboprop, turbofan, or turbojet 

aircraft engine.

    Class TP means all aircraft turboprop engines.

    Class TF means all turbofan or turbojet aircraft engines or aircraft 

engines designed for applications that otherwise would have been 

fulfilled by turbojet and turbofan engines except engines of class T3, 

T8, and TSS.

    Class T3 means all aircraft gas turbine engines of the JT3D model 

family.

    Class T8 means all aircraft gas turbine engines of the JT8D model 

family.

    Class TSS means all aircraft gas turbine engines employed for 

propulsion of aircraft designed to operate at supersonic flight speeds.

    Commercial aircraft engine means any aircraft engine used or 

intended for use by an ``air carrier'' (including those engaged in 

``intrastate air transportation'') or a ``commercial operator'' 

(including those engaged in ``intrastate air transportation'') as these 

terms are defined in the Federal Aviation Act and the Federal Aviation 

Regulations.

    Commercial aircraft gas turbine engine means a turboprop, turbofan, 

or turbojet commercial aircraft engine.

    Date of manufacture of an engine is the date the inspection 

acceptance records reflect that the engine is complete and meets the FAA 

approved type design.

    Emission measurement system means all of the equipment necessary to 

transport the emission sample and measure the level of emissions. This 

includes the sample system and the instrumentation system.

    Engine model means all commercial aircraft turbine engines which are 

of the same general series, displacement, and design characteristics and 

are approved under the same type certificate.

    Exhaust emissions means substances emitted into the atmosphere from 

the exhaust discharge nozzle of an aircraft or aircraft engine.

    Fuel venting emissions means raw fuel, exclusive of hydrocarbons in 

the exhaust emissions, discharged from aircraft gas turbine engines 

during all normal ground and flight operations.

    In-use aircraft gas turbine engine means an aircraft gas turbine 

engine which is in service.

    New aircraft turbine engine means an aircraft gas turbine engine 

which has never been in service.

    Power setting means the power or thrust output of an engine in terms 

of kilonewtons thrust for turbojet and turbofan engines or shaft power 

in terms of kilowatts for turboprop engines.

    Rated output (r0) means the maximum power/thrust available for 

takeoff at standard day conditions as approved for the engine by the 

Federal Aviation Administration, including reheat contribution where 

applicable, but excluding any contribution due to water injection and 

excluding any emergency power/thrust rating.

    Rated pressure ratio (rPR) means the ratio between the combustor 

inlet pressure and the engine inlet pressure achieved by an engine 

operation at rated output.

    Reference day conditions means the reference ambient conditions to 

which the gaseous emissions (HC and smoke) are to be corrected. The 

reference day conditions are as follows: Temperature=15 [deg]C, specific 

humidity=0.00629 kg H2 O/kg of dry air, and pressure=101325 

Pa.

    Sample system means the system which provides for the transportation 

of the gaseous emission sample from the sample probe to the inlet of the 

instrumentation system.

    Shaft power means only the measured shaft power output of a 

turboprop engine.

    Smoke means the matter in exhaust emissions which obscures the 

transmission of light.

    Smoke number (SN) means the dimensionless term quantifying smoke 

emissions.

    Standard day conditions means standard ambient conditions as 

described in the United States Standard Atmosphere 1976, (i.e., 

temperature=15 [deg]C, specific humidity=0.00 kg H20/kg dry 

air, and pressure=101325 Pa.)

    Taxi/idle (in) means those aircraft operations involving taxi and 

idle between the time of landing roll-out and final shutdown of all 

propulsion engines.

    Taxi/idle (out) means those aircraft operations involving taxi and 

idle between the time of initial starting of the propulsion engine(s) 

used for the taxi and the turn onto the duty runway.
