Uncertainty of In-Flight Thrust Determination AIR1678

At present, there are no industry or government standards for determining in-flight thrust or the associated uncertainty. The purpose of this document is to provide information covering methods for estimating the measurement error or uncertainty of in-flight thrust determination in aircraft employing conventional turbofan/turbojet engines. Methodologies beyond those presented are required in order to evaluate configurations such as vectored thrust or V/STOL. The document is intended to be used as a technical guide. It is not intended to be used as a standard or legal document. A companion document, SAE AIR 1703, presents information and guidance on the selection and use of methodologies to predict and assess propulsion system in-flight thrust. Both documents describe comprehensive procedures and tasks for implementing the methodologies. Each program would select those tasks that are appropriate to meet its particular objectives.
