O.K...Thanks for all the info, but let's start this question again.
I understand that airborne, the relitive airflow is not affected by wind (As the aircraft it travelling with the wind in terms of drift...obviously). However, on the ground, in the take-off roll, where the effect of a crosswind is evident...which engine will create the most asymmetric thrust is it were to fail? I already understand the fact you may be holding rudder into wind (therefore reducing you travel available) and it may limit your controlability initially. But any effect to engine perfomance in a crosswind?
