Overview
The TFDi Design MD-11 Extended Simulation Package expands the standard MD-11 by introducing advanced aircraft ownership and maintenance features designed to simulate real-world airline operations. Extended Simulation adds:
- Over 160 aircraft failures
- Circuit breaker functionality
- Aircraft inspections
- Maintenance and repairs
- Routine servicing
- Persistent aircraft wear and tear
- Failure training and practice modes
- Maintenance history logging
Unlike the base aircraft, the Extended Simulation package requires you to actively maintain your aircraft’s condition throughout its operational life.
