Thoughts on CB penatration...

Hi all, just after peoples thoughts on when our hands are tied and there is no other choice apart from the dreaded white knuckle flight through CB's. The main 2 schools of thought I've seen, are 1) to decend into nice thicker air say in the FL250 - 290 range and so giving a much better stall/buffet margin and reducing to turb penatation speed Or 2) Keep within opt cruise levels, only decending if safety of flight becomes in issue.

Upside of decending = much improved stall margin, big downside = Large hail stones FL250-290

Not decending = not as great stall margin, no or very little hail to contend with.

Six of one half a dozen of the other??

Over to you

Thanks
