AESURF
Bulk Data Entry Specifies an aerodynamic control surface as a member of the set of aerodynamic extra points. The forces associated with this controller will be derived from rigid rotation of the aerodynamic model about the hinge line(s).

| CIDi | Rectangular coordinate system with a Y-axis identification number
that defines the hinge line of the control surface
component. (Integer > 0) |

which identifies all aerodynamic elements which make up the control
surface component. (Integer > 0) |
|
| EFF | Control surface effectiveness. 4 Default = 1.0 (Real ≠0.0) |
|
| CREFC | Reference chord length for the control surface. Default = 1.0 (Real > 0.0) |

| CREFS | Reference surface area for the control surface. Default = 1.0 (Real > 0.0) |
Comments
- The ID on AESURF and AESTAT entries are ignored.
- The degrees-of-freedom defined on this entry represent a rigid body rotation of the control surface components about their hinge lines.
- Either one or two control surface components may be defined.
- If EFF is specified, then the forces produced by this surface are modified by EFF (as in, to achieve a 40% reduction, specify EFF=0.60).
- The continuation line is not mandatory.
- The CREFC and CREFS values are only used in computing the non-dimensional hinge moment coefficients.
