You will not be flying an airliner in pilot training. You will start
with basic trainers and work your way up through single-engine and then
multi-engine small planes. You will also have to put in some
"time-building" as an instructor before any airline will touch you.
I am aware of all of these stuffs but I just want to know if you have option in your trainings which aircraft is the best for that time-building you mentioned

thanks for your answer.
