Start capability monitoring enables to reduce delays & cancellations
1. Automatic troubleshooting:
After a ‘No start’, localize the equipments failures in order to minimize
the maintenance operation
2. Diagnosis:
Before a ‘No start’, detect and localize the LRU degradations
3. Prognosis:
Guarantee the start capability for the next flights
Example: Start monitoring on CFM56-7
