Hello fellow aviators,
I’ve completed a personal project to create a comprehensive guide on operating the Airbus A220 (formerly the Bombardier CSeries). The guide is based on real A220 FCOM data, combined with practical experience flying the aircraft. And I’m making it available here for free.
After several hundred hours of work, I managed to condense more than 5,000 pages of FCOM material into a 300-page guide. It covers virtually every aspect of the aircraft, nothing has been “dumbed down” for flight simulator use and nothing has been left out.
This began as a personal project to expand my own notes and summaries to better understand the aircraft, but it gradually grew beyond its original scope. Although it is not intended for real-world operational use (disclaimer), it may be useful as a preparation resource for type training.

Safe landings 
Thank you in advance for your work!
I like this method of explaining v.much 
Very nicely done…can’t wait for the final project to be completed. Thanks for sharing…
If anyone is interested in learning about the A220 already, I managed to describe pretty much every switch with corresponding logics.
That is a brilliant piece of work, thanks

I am trying to draw my own schematics as copying from the FCOM is probably copyright infringement. Takes a long time though…
Yes, i was wondering how long it took to complete one page. Do you fly these IRL?
I do fly the A220 in real life yes
.
The manual looks outstanding. Now all we need is a plane to go with it. 
Got flight controls and electrical system done. Still a lot to do, but I guess the A220 won’t be released anytime soon.
If when you are finished the A220, do you think you might be interested in adapting these to another A… version. I’m thinking maybe all of the Airbus iterations could do with these wonderful tutorials. Maybe even create yourself a website and get a few £’s for each set? They are worth it 
Problem is that I haven’t flown those for real.
I’m working this week, but a few more systems done in the meanwhile.
Hydraulic system done as well 
Wow! Nicely done. When is this aircraft due to be released? Any idea?
Hopefully not before I’m done, but your guess is as good as mine
