Scope
This SAE Aerospace Standard (AS) provides the method for presentation of gas turbine engine steady-state and transient performance calculated using computer programs. It also provides for the presentation of parametric gas turbine data including performance, weight and dimensions computed by computer programs.
This standard is intended to facilitate calculations by the program user without unduly restricting the method of calculation used by the program supplier. This standard is applicable to, but not limited to the following program types: data reduction, steady-state, transient, preliminary design, study, specification, status & parametric programs.
Rationale
Due to the trend towards program implementation in object-oriented languages, this document has been revised to become language independent. Also, the specifics of the traditional FORTRAN implementation have been transferred to ARP4191. Several other updates were made: additions of new engine ratings, ram pressure recovery equations, introduction of ARP5571, rewrite of sections and revision of the units. Also the power definition hierarchy is not specified anymore. It is now left for coordination between the supplier and the user.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
