Hi,
the FCTM
PR-NP-SOP-70 says that one should be able to immediately and simultaneously apply full rudder deflection and full braking.
The way to achieve this is delegated to the individual operators as each have got their own view of this old time argument.
Nevertheless Airbus at one of its training conferences mentioned that their suggestion is for both pilots to keep feet up. The design of the pedals is such to have your whole feet resting on it.
try slide up you feet on that rubber material when landing on 38kt crosswind, or have an engine failure at low speed (below 72kt) on a 30m wide runway, good luck!
