Sec. 34.1  Definitions.


    As used in this part, all terms not defined herein shall have the 
meaning given them in the Clean Air Act, as amended (42 U.S.C. 7401 et. 
seq.):
    Act means the Clean Air Act, as amended (42 U.S.C. 7401 et. seq.).
    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)

[[Page 791]]

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.
