Aileron Control Effectiveness given Aileron Deflection Formula Elements

Variables
Flap Effectiveness Parameter
The Flap Effectiveness Parameter is a measure of how much flaps improve an aircraft's aerodynamic performance.
Symbol: τ
Measurement: NAUnit: Unitless
Note: Value can be positive or negative.
Lift Coefficient Roll Control
The Lift Coefficient Roll Control is a dimensionless quantity that shows how much lift a lifting body creates relative to the fluid density, velocity, and an associated reference area.
Symbol: Cl
Measurement: NAUnit: Unitless
