Hello ppl,
My question is that during our simulators, our instructors have told us to switch off the opposite side F/D in case an engine fails on an ILS approach after VOR/LOC and G/S captures so that the FD which is lost due to eng failure comes up as a result of the other side FD being put off!
Could anybody elaborate on this as to why this has to be done. NO QRH, FCOM talks about this procedure .
Points to be noted,
1. IF an eng fails, does the respective FCC fails, or does it get powered from the opposite side because of the BTB.
2. If FCC fails does the FD also fail or is it independent of the FD. ( my ans as per FCom is it depends on the FCC)
3. and mostly if a loss of a sing gene, does the FCC fail, or only the auto pilot? and of the BTB closes, can the autopilot be re engaged on the failed engine side or no...
Very normal doubts, bordering silly, but would appreciate if anybody can clear these doubts.
Thanks v. much
