Avidyne FlightMax Entegra EFIS -

In S/N's 4697198, 4697216 and up, when the Avidyne FlightMax Entegra EFIS is installed,
instrumentation is integrated into the Primary Flight Displays (PFD) and Multi-Function Display (MFD).
The Data Acquisition Unit (DAU) collects and processes the raw sensor input and provides a refined
data stream to the PFDs and MFD which actually display the data.
See 28-40-00 and 77-10-00 for more information.
WARNING: FAILURE TO CONSULT APPLICABLE VENDOR PUBLICATION(S), WHEN SERVICING
OR INSPECTING VENDOR EQUIPMENT INSTALLED IN PIPER AIRCRAFT, MAY
RENDER THE AIRCRAFT UNAIRWORTHY. (SEE INTRODUCTION - SUPPLEMENTARY
PUBLICATIONS.)
Line maintenance of this system is limited to basic troubleshooting and that is addressed in vendor
publications referenced in 34-20-00.

Engine Condition Trend Monitoring (ECTM)

In the interest of maintaining efficient engine performance, an Engine Condition Trend Monitoring
System has been established by Pratt & Whitney Canada. This is not a mandatory procedure, but is
highly recommended by Pratt & Whitney Canada and Piper. Introduction of the monitoring system when
engines are new or newly overhauled enables the establishment of a performance baseline before any
deterioration of components takes place within the engine. Engine condition can then be observed
without actual teardown of components. The complete procedure can be found in the Engine Condition
Trend Monitoring Analytical Guide (EAG) Manual P/N 3043607, latest revision, available from Pratt &
Whitney Canada.
Engine condition trend monitoring data is automatically recorded by the DAU for subsequent download
to a laptop. Meggitt "Test Mode Terminal" software is required to download this data and transfer (i.e. -
upload) it to the Pratt & Whitney Canada ECTM software.
The DAU ECTM Maintenance Port is located under the instrument panel near the co-pilot's control
wheel. See also 91-95-00, Figure 1.
