MFS,
Thanks for that, mate ... I am now briefed ... the tale was pretty much as I had presumed. I have a Challenger AFM tucked away somewhere ... and will have a looksee when I get a few minutes to spare to dig it out of archives.
Interestingly, with a min weight takeoff's typically 15 kt V2 overrun for the 732 for instance, most people still take a bit of repetitive practice to get on top of the Vmca departure problem as the bird corkscrews itself around the runway ... sometimes I wish I could mount a video on the coaming to record the looks of horror and shock on the pilot's face during the first couple of runs ... as the aircraft rolls through the vertical .. which is about where I normally freeze the box. Seriously, though, I think that this exercise is greatly underrated and that far too many pilots never get to experience, and get on top of, the extremely critical handling of a min weight/min speed takeoff failure.
On another tack .. it is probably useful to put a little bit of explanation to any statements which are out of the ordinary for the interest of those readers who don't have the specific tech background.
I guess if you join up with Mutt and me in the sandpit ... we can style ourselves as the Three Muttsketeers ? ... ah well, I thought it was funny ...
.. anyway, Seasons Greetings to the Canadian engineering fraternity ....
