DEFINITIONS AND SYMBOLS CHAPTER 1. DEFINITIONS Where the following expressions are used in Volume II of this Annex, they have the meanings ascribed to them below: Afterburning. A mode of engine operation wherein a combustion system fed (in whole or part) by vitiated air is used. Approach phase. The operating phase defined by the time during which the engine is operated in the approach operating mode. Climb phase. The operating phase defined by the time during which the engine is operated in the climb operating mode. Date of manufacture. The date of issue of the document attesting that the individual aircraft or engine as appropriate conforms to the requirements of the type or the date of an analogous document. Derivative version. An aircraft gas turbine engine of the same generic family as an originally type-certificated engine and having features which retain the basic core engine and combustor design of the original model and for which other factors, as judged by the certificating authority, have not changed. Note.— Attention is drawn to the difference between the definition of “derived version of aircraft” in Volume I of Annex 16 and the definition of “derivative version” in this Volume. Oxides of nitrogen. The sum of the amounts of the nitric oxide and nitrogen dioxide contained in a gas sample calculated as if the nitric oxide were in the form of nitrogen dioxide. Rated output. For engine emissions purposes, the maximum power/thrust available for take-off under normal operating conditions at ISA sea level static conditions without the use of water injection as approved by the certificating authority. Thrust is expressed in kilonewtons. Reference pressure ratio. The ratio of the mean total pressure at the last compressor discharge plane of the compressor to the mean total pressure at the compressor entry plane when the engine is developing take-off thrust rating in ISA sea level static conditions. Note.— Methods of measuring reference pressure ratio are given in Appendix 1. Smoke. The carbonaceous materials in exhaust emissions which obscure the transmission of light. Smoke Number. The dimensionless term quantifying smoke emissions (see 3 of Appendix 2). Take-off phase. The operating phase defined by the time during which the engine is operated at the rated output. Taxi/ground idle. The operating phases involving taxi and idle between the initial starting of the propulsion engine(s) and the initiation of the take-off roll and between the time of runway turn-off and final shutdown of all propulsion engine(s). Unburned hydrocarbons. The total of hydrocarbon compounds of all classes and molecular weights contained in a gas sample, calculated as if they were in the form of methane. 4/11/99 No. 4 2007/70/II. szám 11/11/93 ANNEX 16 — VOLUME II CHAPTER 2. SYMBOLS Where the following symbols are used in Volume II of this Annex, they have the meanings ascribed to them below: CO Carbon monoxide Dp The mass of any gaseous pollutant emitted during the reference emissions landing and take-off cycle Fn Thrust in International Standard Atmosphere (ISA), sea level conditions, for the given operating mode Foo Rated output (see definition) F*oo Rated output with afterburning applied HC Unburned hydrocarbons (see definition) NO Nitric oxide NO2 Nitrogen dioxide NOx Oxides of nitrogen (see definition) SN Smoke Number (see definition) πoo Reference pressure ratio (see definition) 2007/70/II. szám ANNEX 16 — VOLUME II 11/11/93 PART II. VENTED FUEL CHAPTER 1. ADMINISTRATION 1.1 The provision of this Part shall apply to all turbine engine powered aircraft intended for operation in international air navigation manufactured after 18 February 1982. 1.2 Certification related to the prevention of intentional fuel venting shall be granted by the certificating authority on the basis of satisfactory evidence that either the aircraft or the aircraft engines comply with requirements of Chapter 2. Note.— The document attesting certification relating to fuel venting may take the form of a separate fuel venting certificate or a suitable statement contained in another document approved by the certificating authority. 1.3 Contracting States shall recognize as valid a certification relating to fuel venting granted by the certificating authority of another Contracting State provided the requirements under which such certification was granted are not less stringent than the provision of Volume II of this Annex. 2007/70/II. szám 11/11/93 ANNEX 16 — VOLUME II CHAPTER 2. PREVENTION OF INTENTIONAL FUEL VENTING Aircraft shall be so designed and constructed as to prevent the intentional discharge into the atmosphere of liquid fuel from the fuel nozzle manifolds resulting from the process of engine shutdown following normal flight or ground operations. 2007/70/II. szám ANNEX 16 — VOLUME II 11/11/93 PART III. EMISSIONS CERTIFICATION CHAPTER 1. ADMINISTRATION 1.1 The provision of 1.2 to 1.4 shall apply to all engines included in the classifications defined for emission certification purposes in Chapters 2 and 3 where such engines are fitted to aircraft engaged in international air navigation. 1.2 Emissions certification shall be granted by the certificating authority on the basis of satisfactory evidence that the engine complies with requirements which are at least equal to the stringency of the provisions of Volume II of this Annex. Compliance with the emissions levels of Chapters 2 and 3 shall be demonstrated using the procedure described in Appendix 6. Note.— The document attesting emissions certification may take the form of a separate emissions certificate or a suitable statement contained in another document approved by the certificating authority. 1.3 The document attesting emissions certification for each individual engine shall include at least the following information which is applicable to the engine type:
