This document describes a recommended practice and procedure for the trending of parameters to maintain the test cell correlation status. Trending is performed to monitor test cells for changes that can affect engine performance or the data acquired from engine tests.
The FAA has issued Advisory Circular, AC43-207, on December 26, 2002 that recommends a 7 year re-correlation, trending or periodic checks. The FAA, AC43-207 bases their recommendation on the SAE Aerospace Recommended Practice (ARP) 741 rev. B (or latest revision).
This document describes a recommended practice and procedure for the trending of parameters to maintain the test cell correlation status. Trending is performed to monitor test cells for changes that can affect engine performance or the data acquired from engine tests. Over time the quality of the acceptance test data for an engine can be affected by the test cell environment. This could lead to unanticipated and expensive results of either accepting a poor performing engine or rejecting a good performing engine. The use of trending the data for engine acceptance can avoid such costly errors.

EG-1E Gas Turbine Test Facilities and Equipment
The SAE EG-1E, Gas Turbine Engine Test Facilities & Equipment committee addresses all facets of test facility design, operation, maintenance, calibration and measurement, relating to gas turbine engine testing. The group is dedicated to creating, preparing, and maintaining all relevant specifications, standards, and requirements in this field.

* 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.
