I had exactly 200 hrs TT out of flying school, joined airline on 737 flying 150 people everyday during training, and adjusted just fine, hundreds/thusands more are like me.
SQ puts their cadets on learjet for training, then straight for 777 flying 300 people.
So why feel so insecure having very low time fo on your right? afraid if u cant monitor him/her? with so high hours i m sure thats not even a prob.
