744 F/O Transfer Bus / Right EFIS Control
Anyone with a wiring diagram or MM that can tell me if this is correct.
The F/Os Transfer Bus powers the
R EFIS Control Panel
R FMC
R CDU
LWR EICAS
F/O APU Stby Bus, which in turn powers the,
R PFD/ND.
Cheers.

My 744 TM (unamended) says that the F/O's Transfer Bus powers:
Lower EICAS
FMCS Autothrottle servo
Right ADC
Right EIU
Right FMC
Right FMS-CDU
Right HF
It is also a source for the F/O's APU Standby Bus, which powers:
Right EFIS Control
Right PFD
Right ND
Hope this helps ...

Cheers, that checks with my further investigation, which shows my notes are wrong, the F/Os Right EFIS control must be powered by the F/Os APU Stby Bus as the F/Os PFD/ND are, that way they can be all used as intended.
