Turbulence penetration speed
This is a question I thought I knew the answer too….
During a training detail, in the the decent I was around 270kts. I was quite happy since the turbulence limitation on type was 290-310KIAS /.82 -.85M.
I was told that I had to speed up to the turbulence penetration speed….ie 290-310kts.
This didn’t make sense to me and when I queried it later on the ground I was told that that is the penetration speed. I had never though about turbulence speed being an issue if you were below it and had a large margin on minimum stall speed. I have always though of it as a structural maximum speed. It still doesn't seem correct to me but I am often wrong……could someone please explain this to me and point me in the direction of a reference to an explanation of this situation.
Many thanks
