12.4 Details – LiveView
12.4.1 Self-Test Timeout Flags (SlfTst_stTOutErr)
1 = timeout while waiting for a successful tester intervention (max 1 sec)
1 = timeout while waiting for the ECU switch over for a passive ECU (max 30 sec)
1 = timeout while waiting for the ECU switch over for an active ECU (max 0.5
sec)
1 = timeout when executing the function tests (max 30 sec)
Table 7 Self-Test Timeout Flags
Note:
Bit 0 is the least significant bit or the right most position of the bit mask, bit 15 is the
most significant bit or the left most position.
12.4.2 Self-Test Release Condition Flags (SlfTst_stRls)
1 = Release to start self-test is given (this is a summary bit, if all required condi-
tions are met, it will be set and the self-test will start)
1 = No failure pending (a “0” here would indicate a previous failure status is pre-
venting the self-test from starting)
1 = bit 5 AND bit 6 are set (to 1)
1 = Request of the pilot to start the self-test is present (i.e. the self-test switch in
the cockpit is being pressed)
1 = Pilot request for this run of self-test (detected by rising edge of self-test but-
ton signal).
0 = Self-test has not been started yet or self-test has been deactivated
1 = Power lever is in low idle position (< 5%)
1 = Prop speed is idle (<1000rpm) AND weight on wheels switch is pressed (=
A/C on ground) AND engine run state is NORMAL (bit 2 of “combined engine sta-
tus” must be set, i.e. NOT start, afterrun)
1 = current propeller speed is lower than 800 rpm
0 = current propeller speed is higher than 1000 rpm
Table 8 Self-Test Release Condition Flags
Note 1:
Bit 0 is the least significant bit or the right most position of the bit mask, bit 7
is the most significant bit or the left most position.
Note 2:
Since ECU SW version VC33_x_05_12, a gearbox oil temperature below 40° C
will also prevent the self-test from starting.
