e) Nitric oxide (NO). 3.2 Other information In order to normalize the emissions measurement data and to quantify the engine test characteristics, other information in addition to the requirements of Chapter 3, 3.4 shall be provided as follows: — inlet temperature; — inlet humidity; — atmospheric pressure; — wind vectors relative to engine exhaust axis; — hydrogen/carbon ratio of fuel; — engine installation details; — other required engine parameters (for example, thrust, rotor speeds, turbine temperatures); — pollutant concentration data and statistical validation parameters. This data shall be obtained either by direct measurement or by calculation, as presented in Attachment F to this appendix. 4. GENERAL ARRANGEMENT OF THE SYSTEM Owing to the reactive nature of the exhaust plume from engines using afterburning, it is necessary to ensure that the measured emissions do in fact correspond to those actually emitted into the surrounding atmosphere. This is achieved by sampling the plume sufficiently far downstream from the engine that the exhaust gases have cooled to a temperature where reactions have ceased. No desiccants, dryers, water traps or related equipment shall be used to treat the exhaust sample flowing to the oxides of nitrogen and the hydrocarbon analysis instrumentation. Requirements for the various component sub-systems are given in 5, but the following list gives some qualifications and variations:
