In reading the article, I was far more suprised that Air Canada has a 787!
Okay, aside from that, YYZ has been a source of encursions for quite some time, always appearing to make improvements to operations, rather than fix the underlying issues with taxiways.
Hold lines for the inboard runway are apparently further from that runway than at similar US airports and come up quickly. Very tight arrival spacing, high speeds into the exits and very sharp stops all contribute.
Exactly. Operating with the minimum standards, even though meet criteria, do not meet operations or general human factors. Considering human factors, the number of incursions means the prescriptive design does not work.
In runway/taxiway design, it would be best practice to run the design through airline stakeholders, or if nothing else, learn from the issues, and use it.
Much the same as roadway design, it may work on paper and be approved, but the public driving habits will show you how minimums work.
We operate this configuration when we have the staff for it and never without.
Why does the design or system require extra staffing to operate?
To lighten this up, "Please stop" is a yield sign..."Stop" is a stop sign!
