For Qavion (and any other 744 operators), we have finally nailed the reason for the apparent anomalies with the event record print out. The EIU normally only looks at the #1 ignitors and reports on them. This means that if an EEC has changed the operating ignitor to #2 (flip-flopped on each successive start) that engine will show as ignitor OFF. However, if the stand-by selector or the auto-ignition selector is placed to a specific ignitor, that one will be monitored and reported on in the event record.
Glad that one's finally put to bed !!
