Automatic sensor failure detection for test flights: use case

Context

An aircraft measures a lot of signals, and the customer was having difficulty examining each sensor by hand.

There are 3 different use cases:

1. Training on 2 flights, testing on 2 other flights
2. Training on one type of aircraft and testing on another type of aircraft
3. Outlier detection (detection of anomalies on a single flight without healthy data)

Need

The customer needed automatic failure detection to enable rapid remeasurement.

Solution

DiagFit was used in offline mode to detect anomalies.

Results

100% of anomalies were detected on 3 different use cases, including 2 outside the DiagFit scope. Other anomalies were detected (not seen by the customer).
