Reports say that the A-319 arrived in CYYC under "Direct Law".
The Internet give this definition of Direct Law....
DIRECT LAW
Direct law is the lowest level of computer flight control and occurs with certain multiple failures.
Pilot control inputs are transmitted unmodified to the control surfaces, providing a direct relationship between sidestick and control surface.
Control sensitivity depends on airspeed and NO autotrimming is available.
An amber message USE MAN PITCH TRIM appears on the PFD.
If the flight controls degrade to Alternate Law, Direct Law automatically becomes active when the landing gear is extended if no autopilots are engaged. If an autopilot is engaged, the airplane will remain in Alternate Law until the autopilot is disconnected.
There are no protections provided in Direct Law, however overspeed and stall aural warnings are provided.
The PFD airspeed scale remains the same as in Alternate Law.
In my humble opinion...it seems as if there is more information pointing to a massive comuter glitch over any turbulence issue? Why are the other 100's of trans canadian flight not also reporting some degree of turbulence??
