D. Component Interfaces
(1)
The MCP interfaces are shown in Figure 4. The A channel receives ARINC 429 bus data from FCC-L, C and FMC-L or R. Channel A also transmits data to FCC-L, C, FMC-L, and MAWEA. The B channel receives data from the FCC-R and FMC-R or L. Channel B also transmits data to the FCC-R and FMC-R.
(2)
The AFCS Go-around switches, A/P disengage switches, FLT DIR source select switches, and EICAS FMC switch interfaces are shown in Figure 5. All inputs are analog discretes.
(a) FLT DIR source select switches
1) Each (2) FLT DIR source select switch selects FCC-L, C or R as the data source for F/D displays. The captains switch (P1-1 panel), controls which FCC provides F/D information to the captain's PFD. The F/O's switch (P3-3 panel) controls the first officer's PFD.
