Crosswind landings; if operators place limits on first officers, then with Captaincy how might they judge personal capability in limiting conditions, which they have never experienced before.
Not with simulation, unrepresentative simulation of conditions and little or no lateral acceleration to help judgement of drift correction.
Both management and individual false belief in capability; press on, peer pressure, poorly measured and reported conditions.
Need to add some personal margin. Risk is the amount of uncertainty which has to be managed.
