Good Afternoon Survey The World
Yes I would appreciate the master plan link if you could post it.
As far as our friends involved in the over run in YYZ it was my understanding they were caught by a micro-burst which put them above glide slope leading to a unstableized approach before landing around the mid point of the runway which was wet.
If proposed runway length for YTZ is as suggested in my view it will have thin reserves.
My only experience with Bombardier is the CL-65/100 series where if use engine/wing anti ice is used it was a 15% WAT penalty which resulted in load restrictions x YFC (6,000 foot runway) or leave light and go to YQM refuel for YYZ.
With no comments until accident report is published LGA was always a positive landing with firm braking full reverse which was experienced on the DC-9, B-727, A-319, A-320, A-321, B-767 and a couple on the L1011.
As far as the slide off the runway I think it would be more prudent to wait for the accident report from the NTSB has reviewed and published the report
