All very interesting guys but surely
Vb is a design limitation speed.
If so, is there a definitive answer as to when this speed should be applied?
I have read that : "
Vb - the design speed for maximum gust intensity.
Vb is developed by the designer as a recommended turbulence penetration speed for an aircraft in severe turbulence with varying vertical gust components – up to 50 feet/second for a light aircraft."
So if this is correct does it only apply in severe turbulence?
If we are in moderate turbulence do we have to slow down - comfort excluded.
Everyone seems to have differing opinions and it appears that when to fly at
Vb is not taught.
