L-1011 Trainer Installation: Fuel Indication - Power-On Tests

L-1011 Trainer - Fuel Indication System

Getting the instrumentation online is quite exciting because suddenly the Lockheed L-1011 simulator/trainer gradually starts to come alive. Today I powered up the Fuel Indication system. It consists of 4 tank gauges and a fuel totalizer. The four fuel gauges feed signals to the Fuel Totalizer who then displays the total fuel load and allows for the Gross Weight of the aircraft to be entered prior to takeoff.

I have previously quite extensively blogged about the Fuel Level indicators, and you can find the more detailed blog posting on the Fuel Level indicator and the Fuel Totalizer by clicking on the link.

Below is a video that shows the #2L and the #1 fuel level gauges active and feeding data into the totalizer on the left hand side. For the test the indicators are instructed do point to roughly 1/2 tank full by supplying 5VDC to the instruments.

We are missing a Deutsch 15-S7 connector ... until then we are not able to power up the #3 tank gauge. If you have one ... let me know.
