In a FADEC system, active control switchover occurs
•  on engine startup only.
•  when channels A and B are healthy.
•  on shutdown.

Crystal asking:
•  I think the correct answer is ON SHUTDOWN.
I found the below explanation from a different site.
On the CF6 FADEC, each startup uses an alternative channel.But the switch-over occurs on shutdown of the previous run.The reason for this is that the switch-over at start up might interrupt the start-up sequence.

What is the pressure increase over one stage of a centrifugal compressor?
•  5:1
•  1.2:1
•  8:1

Crystal asking:
•  I think the answer is 8:1 because Jeppesen Gas Turbine Powerplant quotes the latest modern centrifugal compressor as having a pressure ratio of 10:1
