I've been watching this video:
I took notes and compared them with the FCOM volume 1 supplied with the NGX.My questions: (some related to the vid and some not) - In the video, both A and B hydraulic systems are switched on as part of preflight.I read in the FCOM that this is only done if the "nose gear steering lockout pin" is installed.If it's not installed, only system B should be on because system A may cause unwanted tow-bar movement.How do we know if it's installed or not in our NGX? - the after start checklist calls for the engine start levers (fuel cutoff) set at IDLE detent.From what I can tell, there's only off and on. How do I move them to idle detent? - in the FCOM, I found there are THREE takeoff procedures based on the plane's options.These options are: 1. Option - With auto T/O thrust reduction and with FMC U10.7 and earlier2. Option - With auto T/O thrust reduction and with FMC U10.8 and later, FCC Collins P4 and later or FCC Honeywell 710 and later and CDS BP06 and later3. Option - Without auto T/O thrust reduction and with FMC U10.7 and earlier Based on which option the plane has, things like VNAV are engaged at different times of the initial climb.So....again, where do we find out which option our NGX has in order to operate it properly? Thanks for reading!
