V speed derivation
Nice answer.
I read how the SJ30 crashed due to uncontrolled turn to the left from a Vmo test.
Interesting note that many jets while structurely sound seem to be limited to aerodynamic forces that act on the aircraft well before design load limitations are reached.
In the SJ30 case, preliminary reports indicate the pilot put the nose over and the plane at a certain speed was using full scale aeleron deflection to keep the aircraft straight. Any faster and the plane keeps rolling left.
I guess most jets have the same problem. In the Citation SII that I fly, when I get lower(thicker air), in a decent, at Vmo, on the autopilot, once I take it off the autopilot I have to retrim the aelerons to the right.
Food for thought.
