I have a few simple (i hope..) questions regarding the 737-800 and I thought I'll summarise them all here, hope someone with more knowledge could help me with one or all of my questions/problems.
1. Whats the difference between "flt" and "cont" in ignition switchhes. I know that cont should be on to provide continuous ignition during t/o and landing and turbulence and flt to be used in in-flight engine restart but whats the difference in the mechanism? Why can't you use "cont" for in-flight restart? What actually happens in engines when flt is selected?
2.What does the "rwy remain --00ft" do in the takeoff setup page of fmc? Havent found a good answer in previous posts. Something about the position update of the navigation system during t/o roll? When should I use it?
3.On one of the the pre-flight setup pages theres a "wind dir/speed" line, should I put the average total wind speed and direction of my planned route there? Does it affect the FMC fuel consumption calculations? Is there any need to use the specific "rte data" page to enter winds for various legs if I get the assumed fuel calcultions from this already? Or is the idea of entering the wind values for specific waypoints to get correct vnav behaviour? How about the "descent" page "forecast" page, isnt it the same info all over again?
Thanks!
