From data from the TSB briefing this morning.
Doing some quick calculations we get a 0.7 m/s/s deceleration for AF358.
As a comparison a 747 gets 1.14 m/s/s deceleration on a wet runway (1.31 on dry).
That is a loss of 37% braking force beyond a "standard" wet runway.
Or, a loss of 47% braking force beyond a "standard" dry runway.
Losing 42% braking force is a lot !!!
Note: I assumed they touched down near the typical touch-down point.
