engine and APU data.

This recording function is performed automatically

throughout the flight and also upon request by a discrete input to the

FMC. The FWC interfaces with the DL-800 or DL-900 Data Loader for

downloading trend and limit monitor data from FWC memory.

The interface

is over an RS-232 bus.

The FWC performs the ground maintenance test function. This includes

accepting test requests from the DC-884 Display Controller, verifying

that the LRU selected for test is available and ready, and outputting the

specific LRU test commands. Test results are recorded (volatile memory

only) and displayed.

Critical flight data displayed on the PFDs and engine display are

monitored and compared with the original source data.

Additionally, the

FWC assures the integrity of the other wrap-around buses by monitoring

for activity. The monitoring task is performed continuously through the

flight as a means of assuring data integrity.

The FWC initiates the BC test discrete with every cold start power-up on

the ground. The logic required to generate the test request is included

in Section 4.

The FWC digital outputs transmitted on the ASCB are listed

in Table 6-10.
