Just out of simulator and observed reaction when 30 knot airspeed error intoduced into captains airspeed at press of TOGA on take off. RH seat handling. Left seat calls 80 knots - RH seat said "What! mine is just passed 60" am aborting" LH seat says "Negative - no abort above 80 unless fire, failure - continue". In view of ealier contributions to this subject it was most illuminating - the hestitation and confusion that is.
