Sec. 87.89  Compliance with smoke emission standards.

    Compliance with each smoke emission standard shall be determined by 
comparing the plot of SN as a function of power setting with the 
applicable emission standard under this part. The SN at every power 
setting must be such that there is a high degree of confidence that the 
standard will not be exceeded by any engine of the model being tested. 
An acceptable alternative to testing every engine is described in 
Appendix 6 to International Civil Aviation Organization (ICAO) Annex 16, 
Environmental Protection, Volume II, Aircraft Engine Emissions, Second 
Edition, July 1993, which is incorporated herein by reference. This
