Development Programs
In-flight Aircraft Downlinks- Data from RDM and EDI is securely transmitted via wireless and
continuously updating an aircraft information database located at
Teledyne Continental Motors and or Airframe manufactures.
- Database immediately accessible to recognizing faults.
- Flight data comparison between recent flights and base line
engine data.
- Maintenance activity can become on demand using data analysis
- Extended TBO based on recorded data and compared to base lines.
- Gather Data, Analyze Data, Trend Data, Provide Recommendation
on Data.
