本SAE航空航天推荐规程（ARP）标准化了测量飞机燃气轮机发动机烟雾排放的试验设备和程序。包括的程序用于确定和报告烟雾排放量。试验表明，当系统按本文所述正确使用时，实际可实现的烟度精度在+3范围内。本程序不适用于飞行试验，也不适用于补燃模式。

This SAE Aerospace Recommended Practice (ARP) standardizes test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. Tests have indicated that the practically achievable precision of the smoke number is within +3 when the system is properly used as outlined herein. This procedure is not intended for in-flight testing, nor does it apply to afterburning mode.
