A good pilot has to know his machine.
Airbus machines are harder to know than Boeing or other machines.
For a no FD take OFF in the 320 you have to bear in mind, above all, these two items:
1st- select V2 in the FCU
2nd- Never engage A/THR without first selecting a speed higher than actual
for an operator who used a lot of 2 digit airbus 320 msn's in the early nineties and for whom most of the pilots transitioned from the boeing 737-200, there were a lot of early incidents of thrust going to idle immediately after takeoff because of not following above 2 items. after the crash and these incident, the fleet was grounded for 9 months or so.
so
Airbus machines are harder to know than Boeing or other machines.
