The descriptions are a little confusing to me. Maybe my lack of aerodynamic

engineering. **StallDef_StartRatio and StallDef_EndRatio (and others)** Stall

AoA - I assume is Critical Angle of Attack? When you say ratio - to me a ratio

is a fraction - comparing two values - so Ratio of the stall AoA at which …

should be Ratio of the current AoA and stall AoA (critical AoA) at which …

thius gives the 0.9 some meaning that at 90% of the critical AoA the airflow

detaches **StallDef_CurvePower** What is a StallDef_Curve? what is Power -

assume scale factor? **StallDef_minTransition** How does this relate to the

above start and endratios? Default is 0.025 or 1.5 degrees, but .9 to 1.1

start and end in a 16 degree critical AoA is 14.4 to 17.6 - so close to 3

degrees. **StallDef_airflowdetachspeed and StallDef_airflowattachspeed** What

is a ratios per second? efault is 1.0 but I see default 172 aircraft with 10.0

**Stall_TipAddIncidence, Stall_TipAddTwist and Stall_TipTwistScaleRatio** What

is a Vitual? How does this relate to the geometry value set for the wingtwist?

wing_incidence = 1.5 ; Wing incidence (DEGREES) wing_twist = -3 ; Wing twist

epsilon (DEGREES)
