Experience is always gained just after you needed it!
In the good old days of yor we used to fly through CBs all the time. Mainly because we did not understand them. My record was 6 lightning strikes on one trip and we still carried on! I have been in a very overpowered big jet, light, and going down with full power on all 4. I have also been in one going up with idle on all 4, gear down and full flap. Not so long ago I was in a small well overpowered light single about 25-30 miles from a CB and going down with full power on.
These days we know that discretion is the better part of valour. If in doubt there is no doubt.
I was recently called at home late one night by a captain as there were lots of horrible CBs all around the departure airfield and his radar was working. I told him to find a hotel and come home in the morning. Fortunately he was positioning home empty so it was an easier decision. Will not do anyone any favours by breaking the jet.
Being a new F/O is difficult these days for the reasons quoted above. However airmen has offered some good advice. Use it but do not abuse it. Come out with carefully thought out comments along the lines of Airmens comments and you will be respected.
