状态程序既不是初步设计程序，也不是规范程序（由SAE标准as 681C涵盖），而是一个附加类别:它们旨在在程序准备时为一台发动机或一组发动机提供性能的最佳估计，通常包括比规范程序更大的测试经验。

Status programs are neither preliminary design nor specification programs (as covered by SAE Standard AS 681C) but represent an additional category: They are intended to provide the best estimate of performance for an engine or group of engines at the time of program preparation and will normally include greater test experience than a specification program.
