8 Diagnostic Procedures
This chapter details the most important diagnostic steps to be performed during routine
maintenance or fault finding.
Note:
The following procedures assume, that both the AE300-Wizard and the aircraft have
been set up and are connected as described in chapter “6 Overview and First Steps” on page
20.
8.1
Analyzing Operational Data
Both ECUs maintain a non-volatile memory each to store statistical information about the
operation of the engine throughout the whole engine/EECU Life time (if the EECU is being
replaced, the operational data accumulated so far will be lost).
-
This statistical data can be read and interpreted by maintenance organizations
-
The counters used to develop the statistical engine data, engine and ECU run times as
well as the real time clocks (RTC) cannot be reset nor modified in the field.
8.1.1
Engine and ECU Operating Hours Counters
The official engine operating hours to determine service intervals, use in written logs, service
bulletins and so on are being found on the «Engine Logs» tab:
Steps:
1) Connect to ECU
2) Select «Engine Logs» tab
Information:
a) ECU A has been powered up (“electric master” = ON) for 108 h 5 min 43 sec while
ECU B was powered for 108 h 21 min 32 sec
b) ECU A was actively controlling the running engine for 16 h 14 min 41 sec while ECU B
had control of the engine for 9 h 52 min 5 sec
c) The total engine run time so far is 26.11 h (the sum of “b)”)
Note: The two real time clocks of ECU A and B are not synchronized and will deviate over
time. The time is displayed in UTC and valid from the year 2000 through 2100.
