amos2, can I ask some advice?
While very new to jet aircraft I busted an altitude whilst leveling out at cruise altitude in a high speed climb. I had never encountered a climb with a level out into a 150kt jet stream and in my attempt to control the aircraft without throwing passengers around I went 250 foot above assigned cruising level. I have studied our SOP's and couldn't find a reference to leveling out into a jet stream in them. Nor could I find one in the aircraft manual. The endorsement didn't cover that scenario and it hadn't come up in conversation, so unfortunately I found out by making an error, which in turn has given me valuable knowledge.
In your almighty opinion should I have just handed in my notice, packed my bags and set up a fruit and veg stand, or should I continue to learn, including through both my and other peoples errors, making a concerted effort to avoid them and continue to learn every day of my career?
