| L-1011 Trainer - AC Tie Bus and AC Flight Station Buses |
Slowly but surely the power distribution for the trainer is taking shape. Today we worked on the AC Tie bus and the AC Flight Station Buses. The image below shows the three AC Flight Station Buses. Each bus has a relay that is controlled from a "R" labeled circuit breaker on the CB3 panel. There is also a 120V relay that is for sensing voltage on the flight station bus to communicate to the computer as well as the annunciator on the Electric System panel.

Another important AC bus component is the AC Tie bus. The tie bus is used to allow all AC sources to work together or to act as fail over for one another. Below is the AC Tie bus in the current build out phase. The bus has the relays for the three engine generators on the left together with one 120V relay used for sensing power on the bus. Eventually relays for External Power (Ground Power) and the APU simulation will be added.

In additional to the work on the AC buses we also added a few more instruments to the flight engineer's instrument light bus. Below is how far we have gotten in bringing instruments onto the light bus.
