After almost 300 H flying the Challenger (which is incidentally approximately what our pilots fly the Challenger IRL), and more than 300 flighths, the aircraft keeps amazing me.
One of the last flights it threw a NOSE DOOR unsafe at me after take off. Into the hold for trouble shooting, and at the third recycle I got the warning off.
Yesterday I had a 'sticky' APU LCV valve, would not open. ASU start and I was on my way. After a complete power down the LCV came back to life.
Same flight I had the ATS FAIL, not a biggie and good to really get the feeling for manual trust, cleared after a complete power off.
I am wondering is this intentionally built into the aircraft? I have failures OFF(VATSIM controllers don't like aircraft failures). Or is this wear and tear on my machine? Any way, it teaches you the systems and the study guide is invaluable in those cases.
Finally, knowledge of the fuel systems through amongst others the study guide, helped me in explaining a fuel problem we had on our CL650 recently. I was looked at in amazement - how does he know all that? ;-)
